Houston rolled into Saturday, July 25, already sweating, with a muggy, crystal-clear morning that started near 79°F and humidity climbing into the upper 80s at local reporting stations. Inland neighborhoods may see pockets of patchy fog before sunrise, and that thick humidity will make the afternoon sun feel even more brutal. Do not expect much relief overnight either, with lows stuck in the upper 70s.
Afternoon Heat And The Week Ahead
Mostly sunny skies are set to push Saturday highs to around 95°F, with heat index values climbing into the low 100s and potentially hitting about 104°F by midafternoon, especially away from Galveston Bay. Sunday and the start of the work week look even hotter, with daytime highs headed for the upper 90s to near 100°F and heat index readings often topping 105 to 110°F. Overnight lows lingering in the upper 70s will keep the city in a slow bake around the clock. According to the National Weather Service Houston/Galveston, heat advisories are likely if those heat index thresholds are reached.
Morning Fog And The Commute
Patchy fog is possible during the early to midmorning hours for the next few days, with reduced visibility on inland and low-lying routes before conditions improve by midmorning. Drivers should use low-beam headlights, ease off the gas, and leave extra stopping distance wherever the fog thickens. With light south winds in play, most commutes should be fairly calm, if a bit slower in the foggy spots.
Where To Cool Off
The city has opened cooling centers across Houston, with libraries, multi-service centers, and other air-conditioned public facilities available to anyone who needs a break from the heat. Residents can call 311 to find the nearest location, and the official map and full details are available through the City of Houston Office of Emergency Management. Locals are urged to check on older neighbors, limit outdoor activity from roughly noon to 5 p.m., and never leave children or pets unattended in vehicles.
