Houston woke up yesterday to a morning that already felt like late summer. Around 5:35 a.m. CDT, KHOU reported clear skies with temperatures hovering near 79°F and dew points in the mid-70s, the kind of humidity that makes the air feel heavier than the number on the thermometer. With light winds in place, patchy fog or mist could hang around some low-lying neighborhoods through mid-morning, and overnight lows are set to linger in the upper 70s to near 80°F.
Afternoon Heat And Spotty Storms
By Sunday afternoon, July 26, 2026, the heat really starts to flex. Highs are expected to climb to roughly 97°F, with heat-index values possibly topping out near 109°F in the hottest spots. There is a slight chance of inland showers or isolated thunderstorms after 4 p.m., although most of the city should stay dry. Southwest winds will stay on the weak side, around 0–5 mph, so any storms that do fire up will be very hit-or-miss, according to the National Weather Service Houston/Galveston.
This Week's Heat Risk
The heat only builds as the work week gets going. Monday and Tuesday (July 27–28, 2026) are expected to reach the upper 90s to around 100°F, with heat-index readings near or above 105–110°F possible, conditions that may trigger Heat Advisories later in the week. Overnight temperatures will offer little relief, remaining in the upper 70s, and the chance for meaningful, area-wide rain stays low through midweek. A broad area of high pressure will keep the pattern hot and humid into next week, so residents should stay alert for any advisory products from the National Weather Service Houston/Galveston.
Heat Safety And Cooling Centers
If you have outdoor plans, try to move strenuous activity to early morning or evening, keep water close at hand, and check on elderly neighbors and pets during the peak afternoon heat. The City of Houston maintains an online map of cooling centers and heat resources, and residents can call 3-1-1 for help locating a nearby site.
