San Antonio woke up mostly cloudy and muggy early today with temperatures parked in the mid 70s and sticky dew points hanging in the air. Skies are expected to clear, and the afternoon should turn sunny with a high near 96°F and heat index readings climbing as high as 104°F, so anyone with outdoor plans should bring plenty of water. Light south winds around 5 mph are in the mix but will not do much to take the edge off the heat.
This Week's Forecast
The heat is not going anywhere through the end of July. Tomorrow's forecast to reach about 98°F. Tuesday, July 28, and Wednesday, July 29, are expected to top out near 99°F. Thursday, July 30, into Friday, July 31, could push into the 100 to 101°F range. Overnight lows will stay muggy in the mid to upper 70s, and Monday night may bring south southeast winds of 5 to 15 mph, with gusts up to around 25 mph. These numbers, along with the lack of any current watches or warnings, appear in the local forecast from NWS Austin/San Antonio.
Heat Safety And City Resources
The San Antonio Metropolitan Health District has issued a Level II heat advisory, flagging sustained heat index values of 105°F or greater along with warm overnight lows. City officials are urging residents to use libraries, community centers and pools as cooling options during the hottest hours of the day. For a list of cooling sites, fan assistance and other resources, residents can follow guidance from San Antonio Metro Health or call 311 for help.

Planning Ahead
From Monday, July 27, through Friday, July 31, residents should plan to move strenuous outdoor activity into the cooler morning or evening hours and make hydration and shade a priority for children, older adults and outdoor workers. Expect very little relief overnight; hot nights can worsen heat stress, so it is worth checking on neighbors and keeping pets in shaded, well ventilated areas. If you lose power or need help finding a cooling site, call 311 for non emergency assistance, and call 911 for immediate medical emergencies.
