San Antonio gets another sunny, warm day Wednesday, with temperatures climbing to 84 degrees after a clear morning. The city’s dry streak stays intact through the weekend, but a small rain chance finally appears Monday night and Tuesday.

Sunny Afternoons, Mild Nights Through Friday

According to the National Weather Service, Wednesday night will be mostly clear with a low around 63 and light east-northeast winds. Thursday should be mostly sunny near 85, followed by another sunny Friday near 84, with rain chances staying at or near zero.

The latest outlook is a modest update from Hoodline’s earlier forecast, keeping the rest of the week warm but trimming some of the hotter projections. In other words, patio plans still look good, but San Antonio is not quite ready to retire the air conditioner.

Weekend Clouds Arrive Before Early-Week Showers

Saturday will be mostly sunny with a high near 88 degrees, though east-southeast winds may gust to 25 mph. Sunday will be cloudy with a high near 81 and a 10% chance of rain.

Monday is partly sunny near 82, then a 30% chance of rain showers develops Monday night and continues into Tuesday. No watches, warnings or advisories are listed for the San Antonio point forecast, so the main takeaway is simple: enjoy the dry stretch now and keep a light rain backup plan for early next week.
