Tuesday morning, July 28, 2026, started thick and soupy in Austin, with cloudy skies, muggy air, and temperatures sitting near 77°F at Camp Mabry. That steamy wake-up call is only the opening act. By mid to late afternoon, most of the metro is expected to flirt with 100°F under mostly sunny skies. Do not expect much overnight relief either, with lows forecast to linger in the upper 70s.
Today's Forecast
South winds around 5 to 10 mph will stir the air a bit this afternoon, but the setup stays dry with an official forecast high near 100°F. Heat index values could push up to 108°F in the Coastal Plains and Rio Grande Plains, while Austin itself hovers near advisory thresholds. A Heat Advisory is posted from noon to 7 p.m. CDT for those lower-lying coastal areas, according to the National Weather Service.
Heat Safety And Local Resources
Hot afternoons teamed with warm, humid nights stack the deck for heat-related illness. It is smart to dial back strenuous activity from late morning through early evening, stay on top of water intake, and check in on elderly neighbors or anyone with health conditions. If you need a break in the air conditioning during regular hours, the City of Austin notes that libraries and park facilities can be used as cooling centers. Local guidance, locations, and tips are available from Austin Emergency Management.
Looking Ahead
The heat is not packing up anytime soon. Through the rest of the week, daytime highs are expected to hover around 100 to 102°F on Wednesday and then slide into the low 100s heading into the weekend. By Saturday, the hottest spots could nudge into the low 104°F range. Overnight lows are projected to hold in the 77 to 82°F range in the more built-up parts of town, which means nights will offer only limited recovery. Keep an eye on local forecasts and any adjustments to advisories from the National Weather Service.
