San Antonio wakes up cloudy, muggy, and already sticking to the 70s on Wednesday, March 4, 2026, with temperatures near 72°F, high humidity, and a south-southeast breeze. It will be a warm one, with a high near 85°F and a modest shot at scattered showers or an isolated afternoon thunderstorm. In other words, it is an umbrella-optional, frizzy-hair-guaranteed kind of day, with a few gusty spells thrown in.
What To Expect Today
Some light morning drizzle is possible, followed by a slight chance of rain showers through midday and better thunderstorm odds by mid to late afternoon. The National Weather Service calls for south-southeast winds around 10-15 mph, with gusts up to 25 mph and a daytime high near 85°F. Many neighborhoods will stay dry for stretches, but any storm that bubbles up could deliver brief heavy rain and lightning. There are no watches or warnings in effect this morning, though that could change if storms manage to organize later on.
Weekend Rain Chances Rise
Rain chances climb into Friday and ramp up over the weekend (March 6-8, 2026), when forecasters say much of the area has a good chance of at least an inch of rain, with some spots potentially picking up multiple inches. The pattern turns unsettled as multiple disturbances move through the region, so outdoor plans may need a Plan B that involves a roof. For context, this is a noticeable shift from our recent stretch of sunshine - see the earlier Hoodline post on our T-shirt weather for comparison.
How To Plan
Keep a rain jacket or umbrella handy if you will be out late this week, and be ready for pockets of heavy rain that could slow commutes or leave standing water on low-lying streets. Tie down or move loose outdoor items ahead of the gustier afternoons, and keep an eye on updated forecasts and radar if you have weekend events on the books.
