San Antonio woke up on Saturday, May 2, 2026 to a refreshingly cool start, with mid‑50s temperatures, mostly clear skies, and a brisk north breeze. After several soggy days to kick off the month, the Alamo City is finally trading in the umbrellas for sunglasses this afternoon, with sunshine and comfortable air moving in.
Weekend Outlook
Saturday, May 2 stays mostly sunny, with highs landing near 74°F and north‑northeast winds around 10 mph, occasionally gusting up to 20 mph. Saturday night turns mostly clear with temperatures dipping to around 54°F. By Sunday, May 3, things warm up a bit, with highs near 79°F and lighter east winds.

Early Week Heat And A Return Of Humidity
By Monday, May 4, winds swing around from the south and start cranking up the warmth, sending highs into the mid‑80s. On Tuesday, May 5, temperatures could climb into the upper 80s to around 90°F as dew points rise into the 60s and approach 70°F, which will make it feel noticeably more humid. Daytime rain chances stay low Monday and Tuesday, but a low‑end shot at isolated showers or storms shows up late Tuesday night into Wednesday, May 6. Any storms that manage to pop up will be isolated but could pack some strong wind gusts.
What This Means For You
This is a solid weekend for outdoor plans, from yard work to park walks, though you may want to secure patio furniture and lighter tents since winds could gust near 20 mph on Saturday. If you are planning to be out and about from Tuesday evening into the overnight hours into Wednesday, it is smart to have a backup plan ready, since isolated, gusty storms can develop after sunset. Also keep in mind that some rivers and creeks that rose during recent heavy rain may still be hovering near action stage in a few spots, so avoid low‑water crossings and stay tuned to local updates if your route takes you near waterways.
Context
This dry stretch comes on the heels of earlier April storms. Our stormy sunrise and soggy Saturday coverage from April 2 detailed the wetter start to the month and heavier rain bands that moved through the area, which helps explain why some waterways remain swollen in spots.
