San Antonio residents are preparing for a hot week ahead, as temperatures climb steadily into the upper 90s. The weekend begins with mostly sunny skies, highs near 94 degrees, and gentle winds that offer only slight relief. Overnight conditions remain warm, with lows settling near 75 degrees.

Heat Index and Sunday Forecast

Sunday is expected to turn up the heat even further, reaching 96 degrees with a heat index that could feel closer to 100.
