This San Antonio in October travel guide starts with the weather, because October is when San Antonio finally lets you outside. The normal high drops from about 87°F on October 1 to 77°F by Halloween, the 90-degree days that run all summer mostly end in the first half of the month, and the missions, the Mission Reach and the Hill Country come back into play. The calendar fills up at the same time: Halloween nights at Six Flags Fiesta Texas and SeaWorld, the Spurs’ season opener on October 20, the Pearl’s Wednesday night markets and the city’s biggest weekend of the fall, Día de los Muertos, from October 23 to 25, 2026.
This guide is for anyone deciding when in October to come and what to do once here, from families weighing the theme parks to couples planning a Hill Country day. The one caveat is rain. October is one of San Antonio’s wetter months, and its rain tends to come in heavy bursts that can flood low roads and the Mission Reach. Everything here was checked October 1, 2026 against NOAA’s climate normals, the parks’ and event organizers’ own pages, and Texas Parks and Wildlife. For the rest of the year’s calendar, see our San Antonio events and seasonal planning guide.

What is the weather like in San Antonio in October?
October is a month of two halves. NOAA’s 1991 to 2020 normals for San Antonio’s airport put the average high at 82°F and the average low at 60°F for the month as a whole, but those averages hide a steady slide from late summer to early fall. September averages almost 20 days at 90°F or more; October averages 5.6, mostly in its first week or two, and November barely any.
| Date | Normal high | Normal low | What it means for you |
|---|---|---|---|
| October 1 | 86.6°F | 65.3°F | Still summer at midday: outdoor sights in the morning, indoor ones after lunch |
| October 15 | 82.8°F | 60.8°F | The sweet spot: warm afternoons, pleasant evenings, good walking weather |
| October 31 | 77.0°F | 55.1°F | Comfortable all day; a jacket for evenings, especially on the river |
Nights cool off more than days. The month averages five nights below 50°F, nearly all of them late in the month, against almost none in September. If you’re watching a river parade or a Muertos Fest procession after dark at the end of October, bring a layer.
How much does it rain in October?
More than you’d guess from all that sunshine. October averages 3.75 inches of rain, which makes it one of San Antonio’s three wettest months, behind May and September. But it doesn’t drizzle for days. On NOAA’s numbers, any given October day has roughly a 20 to 22 percent chance of measurable rain and only about a 12 percent chance of a tenth of an inch or more. The month averages about four days with real rain, two with half an inch or more, and one day with an inch or more.
That last number is the one to plan around. Heavy Texas rain comes fast, and it floods low-water crossings, creeks and the Mission Reach, the restored stretch of the river south of downtown. The River Walk’s own advice is to stay off the Mission Reach when its sidewalks aren’t visible. If a storm hits, switch to museums for the day; our San Antonio museums guide has plenty to fill a wet afternoon. On the road, never drive into a flooded crossing.
Is October still hurricane season?
Technically, yes: the Atlantic hurricane season runs through November 30. San Antonio sits about 140 miles inland from the Gulf at Corpus Christi, so it doesn’t take a direct hit the way the coast does, but the remnants of tropical systems can still drop heavy rain on the city and the Hill Country. In practice, that means watching the forecast the week before you travel, not avoiding the month.
Early October or late October?
Early October suits theme parks, water and anyone who doesn’t mind heat. Hemisfair’s splash pads run until the end of the month, Aquatica’s season ends in October, and the theme parks’ Halloween events are already running. Mid-October is the best all-round window, with the summer heat gone and the big festival weekend still ahead. Late October brings the best walking weather, Halloween and the Día de los Muertos weekend, along with the month’s biggest crowds and hotel demand.
What to pack
Pack for warm days and cool evenings. Shorts and T-shirts work for most afternoons, but bring long pants or a light jacket for late-month evenings and air-conditioned museums. Add a compact rain jacket rather than an umbrella, since the rain tends to come with wind, plus sunscreen, a hat and a refillable water bottle: an 85°F afternoon in the sun at a mission is still hot. Comfortable walking shoes matter more than anything; the River Walk, the missions and the Pearl are all best on foot.
What’s on in San Antonio in October?
October 2026 stacks a lot into a short stretch. Here’s what’s running, with dates and our verdict on each.
| Event | 2026 dates | Where | Cost | Verdict |
|---|---|---|---|---|
| Día de los Muertos Tradition Trail | October 3 to November 2 | Downtown River Walk | Free | An easy evening walk any day of the month |
| Fright Fest | Select nights, September 11 to November 1 | Six Flags Fiesta Texas | Park admission | For teens and adults who want scares |
| Tricks and Treats | Weekends, September 12 to November 1 | Six Flags Fiesta Texas | Park admission | The gentler Halloween option for younger kids |
| Oktoberfest | Select dates, September 5 to October 31 | Six Flags Fiesta Texas | Park admission | A bonus if you’re already at the park |
| Howl-O-Scream | Select Friday to Sunday nights, 7 p.m. to close, through November 1 | SeaWorld San Antonio | Included with admission | Aimed at mature audiences |
| Halloween-themed days | Every day in October | The DoSeum children’s museum | $18 per person, ages 1 and up | Easy rainy-day fun for little kids |
| Pearl Wednesday Night Market | Wednesdays, 5 to 9 p.m., through November 25 | The Pearl | Free to browse | A relaxed weeknight with dinner |
| Pearl Saturday Farmers Market | Saturdays, 9 a.m. to 1 p.m. | The Pearl | Free to browse | The best Saturday morning in town |
| Spurs season opener | Tuesday, October 20, against Oklahoma City | Frost Bank Center | Ticketed | Book early if you want in |
| Day of the Dead River Parade | Friday, October 23 | Downtown River Walk | Ticketed seats, or free standing room | The month’s most spectacular night |
| Muertos Fest | October 23 to 25 | Hemisfair | Free | Worth planning a trip around |
| Día de los Muertos at Historic Market Square | October 24 and 25 | Market Square | Free to walk in | A daytime complement to Muertos Fest |
The Día de los Muertos weekend
The last full weekend of October is the city’s big one. Muertos Fest fills Hemisfair with more than 80 handmade altars, music and art vendors, free, from Friday, October 23 to Sunday, October 25. The Day of the Dead River Parade sends illuminated barges down the River Walk on the Friday night, and Historic Market Square adds its own altars, mariachi and a dance procession on Saturday and Sunday. It’s moving, colorful and crowded: the festival alone expects more than 135,000 people. Our Día de los Muertos visitor guide has the full schedule, what the altars mean and how to visit respectfully.
Plan it: Muertos Fest free, October 23 (5 to 11 p.m.), 24 (10 a.m. to 11 p.m.) and 25 (noon to 9 p.m.); parade tickets non-refundable; book downtown hotels early for that weekend.
Halloween at the theme parks
Both big parks go dark and spooky in October, and they aim at different crowds. Six Flags Fiesta Texas runs Fright Fest on select nights from September 11 to November 1, 2026, with Tricks and Treats on weekends from September 12 for younger kids and Oktoberfest on select dates through October 31. SeaWorld San Antonio, open on select dates through November 1 this time of year, runs Howl-O-Scream on select Friday to Sunday nights from 7 p.m. to close. It’s included with admission, and SeaWorld itself says it’s aimed at mature audiences.
The honest verdict: with kids under 10, go to Fiesta Texas on a Tricks and Treats weekend in daylight and leave before the scare zones start. With teenagers, Fright Fest is the bigger night out. SeaWorld’s Howl-O-Scream is the better value if you were going to SeaWorld anyway, since it’s included with your daytime ticket. Check each park’s calendar for your exact dates, because both run select days only in the fall. Our San Antonio theme parks guide compares the parks in detail.
Plan it: Fiesta Texas one-day tickets from $45 online plus fees, parking from $39; SeaWorld single-day from $53.99 online, general parking $36 plus tax; Fiesta Texas is about 27 minutes’ drive from downtown and SeaWorld about 30, before traffic.
October with kids
October is an easy month to travel with children. The DoSeum, San Antonio’s children’s museum at 2800 Broadway, is celebrating its 10th birthday in 2026 and makes every day in October Halloween-themed; general admission is $18 for everyone 1 and older, with reduced Museums for All admission available. Hemisfair’s free splash pads run until the end of the month, Fiesta Texas’s Tricks and Treats weekends suit younger kids, and Muertos Fest’s sensory-friendly hours, from 5 to 7 p.m. on Friday, October 23, are a gentler way into the big festival. Halloween falls on a Saturday in 2026, so expect the theme parks and downtown to be at their busiest that weekend. Our San Antonio with kids guide has more ideas by age.
The Spurs’ home opener
The 2026-27 NBA season opens for the Spurs on Tuesday, October 20, against the Oklahoma City Thunder at the Frost Bank Center on the East Side. A season opener is one of the hotter tickets of the year in a basketball city like this one, so if it’s on your list, buy as early as you can and plan your ride: the arena is a short drive from downtown, not a walk.
The Pearl’s markets
The Pearl, the redeveloped brewery north of downtown, is at its best in October. The Saturday Farmers Market runs from 9 a.m. to 1 p.m., rain or shine, and the Wednesday Night Markets run from 5 to 9 p.m. through November 25, 2026. On Sundays, the makers market keeps fall hours of 10 a.m. to 2 p.m., according to the Pearl’s FAQ. The Saturday market is the one to build a morning around: arrive early, eat your way through it, and walk down the Museum Reach of the River Walk afterward, which is a pleasure now that the heat has broken.
Plan it: free to browse; Saturday 9 a.m. to 1 p.m., Wednesday nights 5 to 9 p.m. through November 25; Pearl surface lots charge $13 all day on weekends, so a rideshare or a $1.30 VIA bus can be the cheaper way in.
Oktoberfest, San Antonio style
San Antonio’s German roots run deep, especially in the King William district, and the Beethoven Männerchor, a German singing society with its own hall and biergarten at 422 Pereida St., traditionally holds an Oktoberfest on early-October weekend evenings with German beer, bands and dancing. We couldn’t confirm its 2026 dates and prices, so check the Beethoven’s own site before you go. If you miss it, Fiesta Texas runs its own Oktoberfest dates through October 31.
First Friday
Every first Friday of the month, the Blue Star Arts Complex in Southtown anchors a free art walk from 6 p.m. In 2026 the October edition fell on October 2, and the next is November 6. If your dates line up, it’s a lively, free evening in a part of town many visitors miss.
Which outdoor trips are best in October?
This is the month the outdoor list reopens. In summer, anything without shade is a before-10-a.m. job; by mid-October, you can stay out all day.
The missions and the Mission Reach
The four Spanish missions of San Antonio Missions National Historical Park are free, open daily from 9 a.m. to 5 p.m., and their grounds stay open from sunrise to sunset. They’re also active Catholic parishes, so expect Masses at weekends. In summer, the paved Mission Reach hike-and-bike trail that links them is a punishing, shadeless ride; in October, it’s one of the best things to do in the city. Bring or rent a bike, start at Mission Concepción, about 7 minutes’ drive from downtown, and ride south to Espada, stopping at each church. The Mission Reach is open from dawn to dusk, and after heavy rain it can flood, so skip it if the forecast is bad. Our guide to the San Antonio missions covers each one.
October also opens the season for Rancho de las Cabras, the missions’ old ranch near Floresville, about 23 miles from the park’s visitor center. It can only be visited on free monthly guided tours that run from October to March and last about two hours. Reserve by emailing the park at [email protected].
Plan it: missions free, 9 a.m. to 5 p.m. daily; Mission Reach trail dawn to dusk; Rancho de las Cabras by reservation only, October to March.
Lost Maples State Natural Area
Lost Maples is the Hill Country’s fall color destination: a canyon of bigtooth maples near Vanderpool that turn red and orange in autumn, rare this far south. Texas Parks and Wildlife says October and November are its busiest months and the park reaches capacity daily, so reserve a day pass to guarantee entry. TPWD starts its fall foliage report in mid-October, and the color varies with the weather from year to year, so check the report before you commit to the drive. There’s no cell service in the park, so download your pass and a map before you lose signal.
Plan it: $6 per adult, 12 and under free; open daily 8:30 a.m. to 4:30 p.m.; reserve passes; about 86 miles and just under two hours from downtown each way.
Enchanted Rock State Natural Area
Enchanted Rock is a 425-foot dome of pink granite north of Fredericksburg, with 22 miles of trails, including the short, steep Summit Trail. Its busy season runs from September through May, and October is one of its best months, with cool mornings and warm, dry afternoons when the weather holds. Reserve a day pass to guarantee entry, bring your own drinking water, and know that the Summit Trail can close in wet weather, which matters in a rainy October. Pair it with lunch in Fredericksburg, about 80 minutes from San Antonio, for a full Hill Country day.
Plan it: $8 per adult, 12 and under free; park open 6:30 a.m. to 10 p.m., gate 6:30 a.m. to 8 p.m.; reserve day passes online or at (512) 389-8900; about 87 miles and 1 hour 50 minutes from downtown.
Closer to town
- Guadalupe River State Park. Four miles of river frontage and 13 miles of trails, about an hour north of downtown. October suits the trails more than the water. $7 per adult, 12 and under free, with day passes reservable online.
- Cave Without a Name. Hour-long guided tours of a cave that stays at 66°F, near Boerne, about 67 minutes from downtown. It’s a good rainy-day plan. Adults $23, children 6 to 12 $11.50, plus tax; open 10 a.m. to 5 p.m. from Labor Day to Memorial Day, with reservations requested.
- Gruene and New Braunfels. Gruene Hall, built in 1878 and billed as Texas’s oldest continually operating dance hall, has live music every day, about 46 minutes from downtown. October evenings are ideal for its open-sided hall.
For the full list of Hill Country and Gulf trips, see our day trips from San Antonio guide. If you’ll be visiting several state parks, the $70 Texas State Parks Pass covers entrance fees for the holder and guests at more than 80 parks for a year.
How should you plan an October trip?
Pick your week first, then your plans. Here’s how the month breaks down in 2026.
| Week | Weather | What’s on | Best for |
|---|---|---|---|
| October 1 to 11 | Warm, highs in the mid-80s, a few 90-degree days | First Friday (October 2), the start of the Tradition Trail, theme-park Halloween, Pearl markets | Families, theme parks, the last of the water season |
| October 12 to 22 | Highs in the low 80s, cooler nights | Spurs opener (October 20), Pearl markets, the Tradition Trail | Missions by bike, Hill Country hikes, the best value |
| October 23 to 25 | Highs around 80°F, cool evenings | Muertos Fest, the river parade, Market Square | Culture and spectacle, if you book early |
| October 26 to 31 | Highs in the upper 70s | Halloween, the last Fright Fest and Howl-O-Scream nights, Lost Maples color reports | Fall color, cooler outdoor days |
A long October weekend
If you have three days, here’s a balanced plan. Day one: the missions by bike in the morning, an afternoon at the Alamo and an evening on the River Walk, with the Tradition Trail’s alebrijes lit up after dark. Day two: the Hill Country, either Enchanted Rock and Fredericksburg or Lost Maples if the foliage report looks good. Day three: the Pearl’s Saturday market in the morning, the Museum Reach walk back toward downtown, and either a theme-park Halloween night or, on the last weekend, Muertos Fest. Our San Antonio itineraries have more ways to fill the days.
Hotels and crowds
October is a popular month, and hotel prices follow demand: the Día de los Muertos weekend, big downtown conventions and home games all push them up, while midweek nights are often easier. Book early if your dates fall on October 23 to 25. Staying downtown near the River Walk puts the parade, Hemisfair and Market Square within walking distance; for theme parks, the northwest and west sides put you closer to Fiesta Texas and SeaWorld. Our guide to where to stay in San Antonio compares the areas.
Looking further ahead? The River Walk’s holiday lights switch on with the Ford Holiday River Parade on November 27, 2026, and November brings Luminaria and cooler, quieter days. For the full year at a glance, our month-by-month events planner lays it all out.
San Antonio in October FAQ
Is October a good time to visit San Antonio?
Yes, it’s one of the best. The summer heat breaks, with normal highs falling from about 87°F to 77°F over the month, and the event calendar is full, from theme-park Halloween nights to the Día de los Muertos weekend. The trade-offs are occasional heavy rain and higher hotel demand during the last full weekend of the month.
How hot is San Antonio in October?
Warm, then mild. NOAA’s normals give an average high of 82°F and low of 60°F, but early October can still reach 90°F, with about five or six such days in an average year, almost all early in the month. By Halloween, the normal high is 77°F and nights dip into the mid-50s.
Does it rain a lot in San Antonio in October?
It rains less often than the 3.75-inch average suggests, but harder. Any given day has about a 1-in-5 chance of measurable rain, and the month averages one day with an inch or more. Those heavy days can flood low-water crossings and the Mission Reach, so have an indoor backup plan.
Can you still swim in San Antonio in October?
In places. Hemisfair’s splash pads run through October, and Aquatica operates on select days until the end of the month. River swimming is chillier and unsupervised after summer: New Braunfels’ lifeguards at the Comal River tube chute stop after Labor Day, and the river closes in high water.
Is Fright Fest too scary for kids?
For young children, usually yes. Fiesta Texas pairs Fright Fest with Tricks and Treats, a gentler weekend event for younger kids, so visit by day and leave before the evening scares. SeaWorld’s Howl-O-Scream runs on select weekend nights from 7 p.m. and is aimed at mature audiences.
What should you wear in San Antonio in October?
Layers. Shorts and T-shirts work for most afternoons, especially early in the month, but bring long pants or a light jacket for evenings, which drop toward 55°F by late October. Add a compact rain jacket, a hat and sunscreen, and wear comfortable walking shoes for the River Walk and the missions.
