San Antonio woke up to classic summer soup on Monday, June 22, with cloudy, muggy skies, temperatures around 80°F, and a dew point near 76°F making it feel sticky before breakfast. Low clouds drifting in from the coast are expected to break by late morning, setting up mostly sunny skies and a high near 94°F this afternoon, with the humidity pushing the apparent temperature into the low 100s.
The heat is forecast to peak through the afternoon and evening, with heat-index values up to about 105°F and a south-southeast breeze of 10 to 15 mph that could gust up to 25 mph. Overnight, the air will not offer much relief, with lows only slipping into the upper 70s. According to the National Weather Service, there are no watches or warnings in effect for the Austin–San Antonio area this morning.
Afternoon Heat And Gusty South Winds
Those south-southeast winds will strengthen into the afternoon and can make outdoor work and events feel hotter than the thermometer suggests. Forecasters expect the worst of the heat from about noon through 9 p.m. on Monday, June 22, so outdoor crews, volunteers, and anyone planning to be outside for long stretches should build in water breaks and seek shade when possible. The gusts may also turn unsecured patio umbrellas or lightweight pop-up canopies into awkward kites.
Where To Find Relief
For those who need a break from the heat, the city points to more than 60 public cooling locations, including libraries, community centers, and pools. Officials recommend using air-conditioned public spaces or calling 3-1-1 for assistance. See the City of San Antonio for a map and full list of cooling spots.
Week Ahead
Looking past Monday, dry and warm weather is expected to hold through the work week, with daytime highs mostly in the low to mid 90s and little chance of rain. By the weekend, those highs are expected to climb into the mid to upper 90s. Friday through Sunday, outdoor plans may need a bit of flexibility as peak temperatures tick up a few degrees and gusts may briefly strengthen on some days. Simple steps such as seeking shade, drinking water regularly, and shifting strenuous activity to the morning or evening hours will help cut most heat risk.
The bottom line is that it will not cool off much overnight for the next several days, so residents should treat this as a sustained warm, humid stretch and keep an eye on updates from the National Weather Service if conditions change. If someone you know is particularly vulnerable to heat, you can call 3-1-1 for help finding a nearby cooling location or shelter.
