Texas – A warm breeze is already sliding across San Antonio this morning, and temperatures are set to climb fast, signaling an early burst of summer heat across South Texas.
According to the National Weather Service, skies gradually clear through the day while light winds shift southeast, allowing highs to reach the low 80s today before a sharper jump arrives Monday.
That jump is noticeable. Highs surge to around 89°F Monday, then push into the low 90s by Tuesday and Wednesday. It will feel dry at first, with long sunny stretches and warm afternoons ideal for outdoor plans. Still, the steady south wind may gust near 25 mph at times, especially during the afternoon hours.
Hydration matters now. Limit prolonged outdoor work during peak heat and keep pets cool.
By midweek, the pattern begins to shift.
Moisture returns gradually, and isolated showers begin to develop late Wednesday, especially after sunset. Rain chances sit near 30%, but any storm could briefly intensify with lightning and gusty winds.
Drivers along I-35, Loop 410, and U.S. 281 should watch for slick spots if storms develop during the evening commute. Visibility could drop quickly in heavier bursts.
This is a classic spring setup. Dry warmth builds first, then instability follows.
Looking ahead into early April, above-normal temperatures remain locked in, with more scattered rain chances keeping the pattern active but warm.
Five Day Outlook for San Antonio, TX:
Sunday: Mostly sunny, high near 83°F
Monday: Mostly sunny, high near 89°F
Tuesday: Partly sunny, high near 91°F
