Texas is facing an unprecedented spring heat wave, with temperatures soaring far above seasonal norms across the central and southern parts of the state. In cities like Austin, San Antonio, and Waco, daytime highs have exceeded 100°F (38°C), with some areas approaching 111°F (44°C), according to the National Weather Service.
The scorching temperatures are occurring nearly a month ahead of the official start of summer, setting new local records and straining power grids and emergency services. Meteorologists say the current heat wave is driven by a persistent high-pressure system stalled over the southern United States, preventing cloud cover and trapping hot air near the surface.
In Austin, officials recorded the earliest 100°F day in city history, surpassing a mark previously set in late May. Hospitals across the region have reported an uptick in heat-related illnesses, including dehydration and heat stroke, particularly among outdoor workers and the elderly.
The Electric Reliability Council of Texas (ERCOT), which manages most of the state’s power grid, issued a public conservation notice urging residents to reduce electricity usage during peak hours. While no rolling blackouts have been reported, grid stress remains a concern as temperatures show little sign of easing.
Environmental experts warn that extreme weather events like this are becoming more frequent due to climate change, with Texas especially vulnerable to prolonged periods of heat and drought. Spring wildflowers in parts of Hill Country have wilted early, and fire departments are on alert as dry vegetation increases the risk of wildfires.
The National Weather Service has extended excessive heat warnings across much of Texas through the weekend, with heat indices projected to remain dangerously high. Residents are being advised to limit outdoor activity, stay hydrated, and check on neighbors and vulnerable populations.
