Spring in San Antonio: A Blossoming Dream (Mostly)

Okay, spring (March-May) in San Antonio is pretty much the sweet spot for a lot of folks.

March: The Transition Month

March is a bit of a wildcard. You could get pleasantly warm days in the low 70s, or you might still need a light jacket in the evenings. Average highs are usually in the mid-70s, but lows can dip into the 50s, especially at night. It's basically spring training for summer heat!

Expect a little rain, too, but nothing too crazy usually.

April: Perfect Patio Weather

Ah, April. This is where San Antonio really starts to shine. Expect sunny days with highs in the low 80s – prime time for enjoying the Riverwalk, sipping margaritas on a patio, or exploring the missions. The evenings are still mild, making it perfect for evening strolls. Rainfall is usually minimal.

Seriously, if you can swing a trip in April, do it.

May: The Overture to Summer

May is gorgeous, but it’s the beginning of the climb towards summer’s heat. Highs are typically in the upper 80s, sometimes even creeping into the 90s. You'll start to notice the humidity picking up, too. While beautiful, be prepared to start drinking lots more water! Occasional thunderstorms are also more common in May, but they usually pass quickly.

Summer Heat: Embracing the San Antonio Sizzle (June-August)

Alright, let's be real: San Antonio summers are hot. Really hot. Like, "need-to-find-shade-and-an-ice-cold-drink-ASAP" hot.

June: Stepping Up the Heat

June is the official start of the "bake-off." Highs consistently reach the low to mid 90s, and the humidity really starts to kick in. It's a good idea to plan outdoor activities for early mornings or late evenings to avoid the worst of the heat. Air conditioning is your best friend.

July and August: The Peak of the Inferno

July and August are typically the hottest months, with average highs hovering around the mid-90s and often exceeding 100 degrees. Staying hydrated is absolutely crucial. Seriously, carry a water bottle everywhere. And pack light, breathable clothing. Think loose-fitting cotton. If you're not a fan of heat, you might want to consider visiting during a different time of year.

But hey, on the bright side, the pools are amazing! And the AC is always blasting indoors.

Fall: A Welcome Relief (September-November)

After the summer swelter, fall in San Antonio is like a breath of fresh (and cooler) air.

September: Holding On to Summer

September is still warm, with average highs in the low 90s. The humidity is still lingering, but it's starting to diminish. You'll still need your summer wardrobe, but you might start packing a light sweater for the evenings.

October: The Perfect Balance

October is another incredibly popular time to visit. The temperatures are milder, with highs in the mid-80s, and the humidity is significantly lower. It's perfect for outdoor activities, and you'll see more festivals and events happening around the city. Plus, the fall foliage, while not as dramatic as in New England, still adds a touch of beauty to the landscape.

November: A Touch of Chill

November can be unpredictable. You might still get some warm days in the low 70s, but you'll also start to feel the chill of winter approaching. Average highs are in the low 70s, and lows can dip into the 40s. Pack layers!
