Saturday morning, June 27, Houston rolled out of bed into clear, sticky air and temperatures already sitting in the upper 70s. Highs are set to climb into the low-to-mid 90s today, with heat index values expected to push roughly 100 to 106F each afternoon through Tuesday, so any midday outdoor plans are going to feel downright punishing. South winds will pick up and gust into the 20s later today, and Gulf-facing beaches should brace for rough surf and a stubborn rip-current threat through the weekend.
Afternoon Heat and Humidity
Saturday stays mostly sunny with a high near 94F and heat index readings that could reach around 106F. That level of heat and humidity will hang around through at least early next week. Light south winds near 5 mph will strengthen through the afternoon with gusts near 20 mph, and overnight lows will barely cool off, lingering in the upper 70s to around 80F. A ridge of high pressure is expected to keep rain chances low through Tuesday, cutting off any meaningful break from the mugginess, according to NWS Houston/Galveston.
Beaches and Boaters
Rough surf and a moderate-to-high rip-current risk are on tap at Gulf beaches through the weekend, and small craft should exercise caution in seas around 3 feet. If you are heading to Galveston or other Gulf-facing beaches, pay attention to flag warnings and follow lifeguard instructions. Rip currents can pull even strong swimmers offshore quickly. For the latest patrol information and flag colors, check with beach services before you go.
Beat the Heat
City and county partners have opened cooling sites across the area, including Moody Community Center and Bayland Community Center; call 3-1-1 for current hours and locations before heading out. If you have to be outside, try to avoid strenuous activity between 10 a.m. and 6 p.m., drink plenty of water, and keep an eye on elderly neighbors, young children, and pets who might struggle in the heat. Our earlier roundup has links and a fuller list of cooling options; see our Houston sauna report.
Next Week Outlook
A plume of Saharan dust is expected to slip in Sunday evening through early Tuesday, likely bringing hazy skies and slightly reduced air quality for sensitive groups. Rain chances stay low until midweek, when isolated afternoon storms could reappear Wednesday as gulf moisture increases. If you have outdoor plans later in the week, keep an eye on updated forecasts. Either way, afternoons will stay hot and humid.
