Austin began Thursday under mostly cloudy skies with temperatures near 79 degrees, but the morning cloud cover is a brief opening act. Sunshine will push the city toward 100 degrees by late afternoon, with heat index values as high as 107 in a forecast that stays hot and largely dry through next Wednesday.
Thursday Turns Sunny And Brutally Hot
Temperatures are expected to climb through the 80s and 90s before topping out around 100 degrees Thursday afternoon. South winds should stay light near 5 mph, and the rain chance in Austin is just 2%, so shade and air conditioning—not a passing shower—will be the main relief.
Thursday night will remain mostly clear with a low near 77, while the heat index may still reach 105 earlier in the evening. No heat advisory is posted for Austin in the current forecast, but those numbers can still be hazardous for people working or exercising outdoors.
Weekend Heat Offers Little Relief
Friday brings mostly sunny skies and a high near 98, followed by another mostly sunny Saturday and Sunday with highs near 98. Overnight lows will hover around 77, and light south winds will do little to erase the accumulated heat.
A Brief Storm Chance Monday
A slight chance of showers and thunderstorms arrives after 1 p.m. Monday, but the chance is only 20% and most of the day should remain mostly sunny near 98. Tuesday and Wednesday then climb back to around 100 under sunny or mostly sunny skies, keeping the seven-day outlook stubbornly hot.
Plan Around The Hottest Hours
The safest window for outdoor errands, exercise and yardwork will be early in the morning or after sunset, with frequent water breaks and extra attention to children, older adults, outdoor workers and pets. Residents looking for an air-conditioned break can check the City of Austin's heat guidance for cooling-center information and heat-illness resources.
