San Antonio woke up sticky Friday, May 15, under low clouds and muggy early‑morning air with temperatures in the low 70s. By afternoon, readings climb into the low 90s, with a high near 93°F, while southerly winds ramp up and make it feel even warmer than the thermometer suggests.
Afternoon Winds Pick Up
South winds this afternoon are expected to run about 5 to 15 mph, with gusts as high as 25 mph, and that breeze should stay gusty into the evening. Tonight, the low drops to around 71°F with south‑southeast winds of 10–15 mph and occasional stronger gusts. According to NWS Austin/San Antonio, some neighborhoods could see gusts up to about 25–30 mph through the weekend.
Weekend Outlook
The weekend stays mostly dry, with partly to mostly sunny afternoons and highs around 92°F on both Saturday and Sunday. Overnight lows will hang in the low to mid 70s, so evenings outdoors will stay warm and muggy. Rain chances remain small, so most outdoor plans should be fine, but expect sticky air and peak afternoon heat to make things feel a bit oppressive.
Stormy Turn Next Week
Forecast guidance points to a pattern shift early next week, when scattered showers and thunderstorms become more likely Monday, then ramp up Tuesday and Wednesday. Locally heavy rainfall is possible in that Tuesday to Wednesday window. Humidity will climb, and in some spots heat indices could feel like 100–105°F Sunday through Tuesday, which raises heat‑safety concerns for outdoor workers and vulnerable residents. Stronger storms may bring brief heavy downpours and gusty winds that increase the risk of localized flooding. As noted by NWS Austin/San Antonio, midweek currently looks like the wettest stretch, when both storm coverage and rainfall totals are expected to increase.
Plan Ahead
If you are heading outside this weekend, try to schedule the toughest chores or workouts for morning or evening, keep water close, and secure loose patio furniture or decorations so they do not go flying in the gusts. The City of San Antonio keeps a list of cooling centers, heat‑safety tips, and resources for residents without air conditioning. Call 311 or check local listings for hours and locations. For details and a map of places to stay cool, see the City of San Antonio.
Bottom line: expect a hot, windy Friday and a mostly dry but muggy weekend, followed by a wetter, stormier stretch early next week that could take the edge off the heat while briefly increasing flood and lightning risks. Keep an eye on updates from local forecasters so you can tweak outdoor plans as the storms move in.
