Tuesday morning, March 24, 2026, Austin woke to clear skies and temperatures in the mid-60s, but that comfortable start is not sticking around for long. Patchy fog early may slow the commute before mid-morning, and afternoons are set to feel much hotter as highs climb into the upper 80s to near 90 over the next few days.
Midweek Heat Spike and Fire Concerns
Forecasters expect a rapid warm-up today, with highs near 88°F, then a bump to around 91°F on Wednesday and Thursday as steady southerly winds pick up, with gusts reaching about 20 to 25 mph. Low overnight humidities paired with those breezy south winds could push fire weather into the elevated to near-critical range on most workdays this week, according to NWS Austin/San Antonio.
Foggy Drives, Sun-Soaked Afternoons
Patchy fog is most likely before 10 a.m., especially in low-lying neighborhoods and along the I‑35 corridor, where visibility can drop on bridges and open highway stretches. By mid-morning, the fog should lift, leaving mostly sunny, dry afternoons that make outdoor plans feel hotter than the thermometer alone suggests.
Staying Cool and Cutting Risk
To stay comfortable, drink plenty of water, ease up on strenuous outdoor work during the warmest hours, and reach for sun protection if you will be outside in the afternoon. The city posts heat-awareness guidance and cooling options for residents; see the City of Austin for local cooling-center information and tips.
Keep an eye on local alerts before you head out, and be extra cautious with yard debris or outdoor equipment while the air stays dry and gusty. We will update this outlook if the National Weather Service or the city issues any warnings or advisories later this week.
