Houston rolled out of bed into a steam bath Sunday morning, June 28, 2026. Skies are clear and temperatures were already hovering near 80°F at dawn, with thick humidity wrapped around the city. Dew points are stuck in the mid-70s, and there is little overnight relief in the forecast. Mostly sunny afternoons and stubbornly warm nights are expected through early next week, so outdoor events and even casual evening walks will stay hot and sticky. If you are headed outside this afternoon, take frequent water breaks and check on older neighbors and pets.
Afternoon Heat And Gusty South Winds
Afternoon highs will climb into the mid-90s, with around 94°F expected Sunday and close to 95°F on Monday. Factor in the humidity and heat index values jump into the low to mid-100s, roughly 103-107°F during the hottest part of the day. Southerly winds of 5-15 mph will pick up and turn gusty in the afternoon, with gusts up to 25 mph possible, which can make outdoor labor and long stretches in the sun more dangerous for vulnerable people. Nights will only dip into the upper 70s to around 80°F, so there will not be much cooling even after dark. According to the National Weather Service Houston/Galveston, the region faces a moderate to major heat risk through at least Tuesday.
Coast, Dust, And What To Do
Conditions along the coast are not exactly inviting either. Beaches will carry a high rip-current risk through Monday, and 3-5 foot seas combined with steady southerly winds will make swimming and small-boat operations hazardous. Late Sunday into Monday, Saharan dust is expected to float in, creating hazier skies and a possible short-term hit to air quality for people with breathing issues.
If you need a break from the heat, the city maintains cooling-center listings and local resources; check cooling centers and neighborhood options for details. Plan beach trips with caution and avoid entering the surf when rip currents are flagged.
When Relief Might Arrive
Rain chances stay low through the start of the week but tick up a bit by midweek as the ridge shifts. Forecasters expect isolated, sea-breeze triggered storms, with probabilities of precipitation generally in the 15-30% range from Wednesday into Friday. That means widespread relief from the heat is unlikely until later in the week, so keep a close eye on hourly forecasts if you have outdoor plans beyond Tuesday. Officials are urging people to take heat precautions and to check official updates before heading to the coast or scheduling strenuous outdoor work.
