Decoding San Antonio Average Temps: A Guide for the Uninitiated (and Maybe Even Some Locals!)
Okay, so you're thinking about visiting or maybe even moving to San Antonio, Texas? Smart move! It's a city steeped in history, brimming with culture, and blessed with (mostly) amazing food. But let's be real, the weather can be a bit of a rollercoaster. That's why understanding San Antonio average temps is essential for planning your trip, packing your suitcase, or just mentally preparing yourself.
Don't worry, I'm here to break it all down for you. We'll go season by season, month by month, and even touch on those crazy weather anomalies that occasionally hit the Alamo City. Let's dive in!
The Sweltering Summer: June, July, and August
Alright, let's rip off the band-aid first. San Antonio summers are hot. Like, really hot. We're talking daily San Antonio average temps consistently in the 90s, sometimes creeping up into the triple digits. And the humidity? Oh, the humidity. It can feel like you're walking through soup some days.
June is usually a warm-up, with average highs hovering around 90°F (32°C). July and August are the peak heat months, often seeing average highs around 95°F (35°C), but don't be surprised if you experience multiple days exceeding 100°F (38°C). The lows? They're not much relief, usually staying in the low to mid-70s (around 22-24°C).
Basically, if you're visiting during the summer, pack light, breathable clothing, invest in some good sunscreen, and stay hydrated. Seriously, hydrate! And maybe plan your outdoor activities for early mornings or late evenings when the sun isn't quite so brutal. Think Riverwalk strolls at dusk, not midday sightseeing.
The (Usually) Mild Fall: September, October, and November
Ah, fall. My personal favorite time of year in San Antonio. The brutal heat starts to break, the humidity drops, and the evenings become wonderfully pleasant. It's the sweet spot between scorching summer and the occasional winter chill.
September can still be pretty warm, with average highs in the low 90s (around 32°C), but the evenings start to cool down, offering a welcome respite. October is when things really start to shine, with average highs in the low 80s (around 27°C) and lows dipping into the 60s (around 16°C). Think perfect patio weather!
November is a bit of a transitional month. You might get some days that feel like a warm extension of October, but you'll also start to experience some cooler days, with average highs in the low 70s (around 21°C) and lows in the 50s (around 10°C). You'll probably want to start layering your clothing at this point.
The (Sometimes) Chilly Winter: December, January, and February
Okay, so "winter" in San Antonio is a relative term. We're not talking about snowdrifts and frozen tundra here. In fact, snow is a pretty rare occurrence. But it can get chilly, especially at night.
December is usually mild, with average highs in the low 60s (around 16°C) and lows in the 40s (around 4-7°C). January and February are generally the coldest months, with average highs in the upper 50s (around 13-14°C) and lows dipping into the low 40s (sometimes even the 30s!).
Now, those are just averages. San Antonio is known for its unpredictable weather. We might have a week of warm, sunny days in the middle of January, followed by a sudden cold snap with freezing temperatures. It's always a good idea to be prepared for anything!
And don't be surprised if you hear about a "blue norther" sweeping through. These are fast-moving cold fronts that can drop temperatures dramatically in a short period of time. They're usually brief, but they can definitely catch you off guard if you're not expecting them.
The Breezy Spring: March, April, and May
Spring in San Antonio is a beautiful time to visit. The wildflowers are in bloom, the weather is generally pleasant, and the city is buzzing with activity.
March can be a bit unpredictable, with average highs in the low 70s (around 21°C) and lows in the 50s (around 10°C). You might get some warm days, but you'll also probably experience some cooler spells. April is usually much more stable, with average highs in the mid-70s (around 24°C) and lows in the 60s (around 16°C).
May is when things really start to heat up, with average highs in the low 80s (around 27°C) and lows in the upper 60s (around 20°C). You might even get a taste of that summer heat towards the end of the month.
A Few Words About Tornadoes and Other Weather Oddities
While San Antonio isn't exactly "tornado alley," we're not immune to severe weather. Tornadoes are relatively rare, but they do happen occasionally, especially during the spring months. It's a good idea to be aware of the warning signs and have a plan in place in case a tornado threatens.
Flooding can also be a concern, especially during periods of heavy rainfall. The San Antonio River can swell quickly, and low-lying areas can be prone to flooding. It's important to be aware of flood warnings and avoid driving through flooded streets.

San Antonio weather can be fickle, but with a little preparation, you can enjoy all that this amazing city has to offer, no matter the season. Now, go out there and explore!
