Austin, Texas – Temperatures surge into the 90s by Sunday afternoon, pushing early-season heat across South-Central Texas and raising concerns for dehydration and increased energy use during peak hours.
According to the National Weather Service in Austin/San Antonio, highs will climb to 93°F in Austin, 92°F in San Antonio, and as high as 98°F in Del Rio by Sunday afternoon, with dry air and clear skies holding steady through at least Friday evening. Rain chances remain near zero across the region.
Cities along the I-35 corridor, including New Braunfels and San Marcos, will see daily highs between 89°F and 92°F through midweek. Hill Country communities like Fredericksburg and Kerrville stay slightly cooler but still push upper 80s to near 90°F. Overnight lows remain mild, ranging from 55°F in rural valleys to mid-60s in urban areas.
Drivers should expect increased glare during evening commutes, while residents are urged to limit outdoor activity between 2 p.m. and 6 p.m., hydrate, and check on vulnerable neighbors. Energy demand may spike as cooling systems run longer each day.
This dry, pattern holds firm through Friday, with the next meaningful weather shift not expected until next weekend. Additional updates may follow if heat advisories are issued.
