# Texas heat wave 2026 > Live situation record from CLSTR: https://clstr.news/situations/texas-heat-wave-2026 > Updated: 2026-08-03T00:00:00.000Z. Sources: 14. Developments: 5. The July‑August 2026 Texas heat wave has persisted, with daily highs frequently reaching or exceeding 100 °F and heat‑index values topping 110 °F across the state. Early July brought a weakening cold front that sparked thunderstorms, localized flooding, hail and wind gusts up to 65 mph before humidity surged and temperatures climbed toward 100 °F. By July 21, ERCOT projected peak electricity demand of 80,000–90,000 MW, approaching the all‑time record of 85,508 MW set in August 2023, while a possible Gulf tropical storm added further humidity and strain on the grid. A persistent heat dome kept inland areas such as Corpus Christi at 106‑108 °F, with only a brief, weak cold front offering minimal rain and modest relief. In early August, the drying of grasses and fuels under triple‑digit heat prompted burn bans in 93 counties and heightened wildfire danger. An air‑quality alert warned of respiratory risks in North Texas, and isolated severe storms introduced hail, damaging winds and flash‑flood concerns. Authorities continue to urge residents to stay hydrated, limit outdoor activity during peak heat, pre‑cool homes, and keep emergency kits ready in case of power outages or fire incidents. ## Claims - Extreme heat and humidity in Texas can lead to heat exhaustion and heat stroke.
