Houston, TX, July 26, 2026 —
Houston residents are preparing for a significant and potentially dangerous heatwave set to grip the region starting next week. Forecasters are predicting daily high temperatures to reach or exceed 100°F beginning Monday and persist through Friday.
The mercury is expected to hit 100°F on Monday, with temperatures climbing further into the week. Highs are forecast to remain between 100°F and 102°F from Tuesday through Friday. These extreme daytime temperatures are accompanied by a dangerous heat index, which measures how hot it feels to the human body when relative humidity is factored in. The heat index is anticipated to reach between 107°F and 110°F, prompting the issuance of heat advisories for the area.
Adding to the discomfort and risk, overnight temperatures are not expected to provide significant respite. Lows are predicted to hover around 80°F, offering minimal cooling relief after the intense daytime heat. This lack of substantial overnight cooling can exacerbate the health risks associated with prolonged exposure to high temperatures.
Officials are urging residents to take precautions to prevent heat-related illnesses. These precautions typically include staying hydrated, limiting outdoor activities during the hottest parts of the day, seeking air-conditioned environments, and checking on vulnerable individuals such as the elderly and young children.
