KSAT Weather San Antonio 10-Day Forecast: What to Expect This Week

The next 10 days in San Antonio will bring a mix of warm afternoons, mild evenings, and scattered chances of rain, according to the latest KSAT weather outlook. Residents should prepare for temperatures ranging from the mid-70s at night to the upper 90s during the day, with humidity levels staying moderate to high. While no severe weather is currently forecast, brief showers and thunderstorms could develop, especially in the late afternoon or evening hours.

Highs and Lows: Daily Temperature Trends

Expect daytime highs to peak between 95°F and 99°F through the weekend, with overnight lows dipping to the mid-70s. The warmest stretch appears to be Tuesday through Thursday, when temperatures may approach triple digits in some areas. If you’re planning outdoor activities, schedule them for early morning or late evening to avoid the peak heat.

Humidity will add to the discomfort, making it feel closer to 105°F during peak afternoon hours. Staying hydrated and taking breaks in air-conditioned spaces will be essential, particularly for sensitive groups like children, the elderly, and those with respiratory conditions.

Rainfall and Storm Chances: When to Expect Showers

Scattered thunderstorms are possible each afternoon and evening, with the highest chances on Wednesday and Friday. While rainfall amounts should remain light—typically under a quarter-inch per event—gusty winds and brief downpours could briefly disrupt outdoor plans. Keep an umbrella or light jacket handy if you’re heading out after 3 p.m.

For those tracking daily conditions, KSAT’s updated forecast will refine storm timing as the week progresses. A quick check of the radar before heading out can save time and frustration.

Air Quality and Outdoor Safety

With high temperatures and moderate humidity, air quality may dip into the “moderate” range on some days, particularly for ozone. If you notice haze or experience throat irritation, limit strenuous outdoor activities. Children playing sports or adults gardening should take extra precautions, such as wearing masks or scheduling workouts for cooler parts of the day.

Weekend Outlook: A Slight Cooldown Ahead

By Sunday, temperatures may ease slightly into the low 90s as a weak cold front approaches. While this won’t bring dramatic relief, it could reduce humidity levels and lower storm chances for the start of next week. Outdoor events planned for the weekend should still account for possible afternoon storms, but the overall pattern suggests a more comfortable stretch.
