Austin is waking up to near-79-degree temperatures Saturday, but the brief morning calm will give way to another day of punishing heat. The high is expected to reach 105 degrees, with the heat index climbing as high as 109.
A Heat Advisory is in effect for Austin and the broader I-35 Corridor through 7 p.m. Sunday, with heat-index values potentially reaching 111 degrees. The National Weather Service warns that the combination of high temperatures and humidity may cause heat illnesses.
A Brief Storm Chance Won’t Break The Heat
There is a slight chance of showers and thunderstorms after 4 p.m. Saturday, but the odds are only around 13%. Any storm that develops should be brief, though a quick downpour or gusty winds could offer temporary relief before the heat settles back in.
Saturday night will remain warm, with a low near 79 and partly cloudy skies after the evening storm chance fades. Sunday looks sunnier and just as hot, with a high near 105 and only a 3% chance of rain.
Triple Digits Continue Into Next Week
Austin’s heat wave is not packing its bags after the weekend. Forecast highs reach 104 degrees Monday and Tuesday, 105 Wednesday, 104 Thursday and 103 Friday, while overnight lows stay mostly between 79 and 80.
Winds will generally remain light from the south or southwest, offering little help during the afternoon. The extended forecast also shows mostly sunny or clear conditions, with no meaningful rain or cooldown currently expected.
Plan Around The Hottest Hours
Residents should drink plenty of fluids, stay in air conditioning when possible and avoid strenuous outdoor activity during the hottest part of the day. Lightweight clothing, shade and frequent breaks are especially important for outdoor workers, runners and anyone attending weekend events.
Heat exhaustion symptoms can include heavy sweating, weakness, dizziness and nausea. Confusion, fainting or hot, dry skin can signal heat stroke, which is an emergency requiring a 911 call.
