Austin tied its daily heat record on Saturday, reaching 107 degrees at Camp Mabry and capping an intense late-summer heat wave that weather officials warn will persist through the middle of next week, according to the National Weather Service.
The scorching temperature matched the Aug. 22 record set in 2024, making Saturday the city’s hottest day of the year so far and surpassing the previous 2026 high of 104 degrees. The extreme conditions arrived as thousands of new University of Texas students moved onto campus for the annual Longhorn Welcome events, while crowds gathered across town for the Austin Pride Festival at Fiesta Gardens.
According to the National Weather Service, an Extreme Heat Warning remained in effect for Travis County until 7 p.m. Sunday. Forecasters stated that a Heat Advisory will take effect immediately afterward and remain in place through 7 p.m.
Meteorological Drivers Behind the Texas Heat Wave
According to National Weather Service meteorologist Bob Fogarty, a powerful high-pressure system centered over West Texas and New Mexico is driving the prolonged heat wave across the region. The ridge covers the entire state and much of the south-central United States, locking in stagnant atmospheric conditions.
“It lets us warm up almost as much as we possibly can at any given day in the summer like this.”
Fogarty noted that clear skies and a lack of wind prevent atmospheric mixing, allowing temperatures to climb steadily each afternoon. “All sunshine, not much clouds, not much wind to mix things up, so it just tends to be sort of stagnant, and that lets it get hotter,” he said. “It’s not showing signs of changing over the next few days, so we’re going to stay pretty hot.”
Impact on Major Austin Events and Students
The record-breaking temperatures coincided with major outdoor gatherings in the city, forcing organizers to implement safety precautions. UT Austin scheduled outdoor events from midday through sunset for incoming students participating in Longhorn Welcome.
Simultaneously, the Austin Pride Festival ran from 11 a.m. to 6 p.m. at Fiesta Gardens. Festival organizers provided free water stations and permitted attendees to bring reusable water bottles onto the grounds. While temperatures cooled slightly by the time the Austin Pride Parade began at 8 p.m., readings remained in the 90s past 10 p.m., according to local reporting.
Forecast and Outlook for Central Texas
Camp Mabry was forecast to reach 106 degrees on Sunday, which would tie the daily record for Aug. 23 set in 2010, with some locations across South Central Texas potentially hitting 107 degrees, according to the National Weather Service. Forecasters indicate that relief will not arrive quickly.
