By 5:35 a.m. CDT on Tuesday, June 23, 2026, Houston was already off to a sticky start, with clear, muggy air sitting near 81°F and a dew point hovering around 77°F (25°C). Patchy smoke is expected to linger through the morning before skies open up to a blazing afternoon, with a forecast high near 94°F and heat-index values that could push up toward 106°F later today.
Afternoon Heat
The worst of the heat is likely between about 2 and 6 p.m., when south winds should run around 5 to 10 mph and rain chances stay very low. Heat-index readings across many neighborhoods are expected to climb into the low to mid-100s, posing a serious risk of heat stress for outdoor workers and vulnerable residents, according to the National Weather Service.
Patchy Smoke
Forecasters expect patchy smoke to hang over parts of the city into the late morning, leading to hazy skies and, at times, reduced visibility on some roadways. People with asthma or other breathing issues may want to ease up on strenuous outdoor plans until the smoke thins out.
Beach And Surf
Along Gulf-facing beaches, a high rip-current risk is on tap through the evening. The water may look perfect for a swim, but currents can yank swimmers offshore in a hurry. Lifeguards and beach patrols are urging people to follow flag warnings and avoid venturing into the surf, and small-craft operators are being advised to use extra caution.
Heat Safety And Cooling Centers
City and county partners have opened a network of cooling sites across the region. Local options include Moody Community Center (3725 Fulton St) and Bayland Community Center (6400 Bissonnet St). For a full list of locations and daytime hours, local reporting has pulled together participating sites and schedules; you can also call 3-1-1 if you need help finding a place to cool off (Click2Houston).
