Austin is waking up warm and sticky this morning, with mostly cloudy skies, temperatures already around 75°F, and stubbornly high overnight dewpoints keeping things oppressive even before breakfast. Sunday, July 26, 2026, is expected to top out near 99°F, with heat index values pushing into the mid 100s. After sunset, do not expect much relief, as lows should only slip into the mid to upper 70s. Forecasters say this steamy pattern is locked in for the coming week, so outdoor plans may feel more like endurance events than summer fun.
What To Expect This Week
Highs near 99°F are on tap for Sunday and Monday (July 26–27), with heat index readings that could reach about 106–107°F. By Tuesday and Wednesday, temperatures are projected to climb into the low 101°F range, and Thursday and Friday could be even hotter, nearing 103°F. There is little to no rain in the forecast through the end of July, and as of this morning no watches or warnings are in effect. This outlook comes from the NWS Austin/San Antonio, which notes increasing heat risks as the week drags on.
Heat Safety And Cooling Resources
With warm overnight lows teaming up with daytime triple digits, the risk of heat exhaustion and related illness goes up, especially for anyone working or playing outside for long stretches. Shift strenuous activity to early morning or evening hours if you can, drink water consistently, and check in on older neighbors, infants, and anyone without reliable air conditioning. The City of Austin maintains a network of summer cooling resources, including many public libraries and Parks & Recreation facilities that double as cooling centers, and it posts current locations and hours online through the City of Austin. As always, never leave people or pets in parked cars, even for a short errand, and keep water handy any time you step outside this week.
