Saturday Night’s Outlook: Warm and muggy conditions persist for the Houston/Galveston area. Overnight low temperatures are forecast to be 74-79°F inland and 75-83°F at the beaches. Patchy fog is possible around sunrise, accompanied by light and variable winds. Data updated on August 29, 2026.
Sunday’s Outlook: Hot and humid conditions are expected to continue. The forecast includes a slight chance for isolated showers and thunderstorms in the afternoon, with variable winds at 4-8 mph. High temperatures will range from 95-99°F inland and 92-95°F along the beaches, with heat index values reaching 102-107°F. Data updated on August 29, 2026.
We are monitoring two disturbances, one in the Gulf and the other east of the Caribbean (Remnants of Dolly). Both have a low chance of development. The Gulf system may enhance shower and thunderstorm activity over southeast Texas by Tuesday.
Atmospheric conditions are expected to be favorable for producing high levels of ozone pollution across the Houston, Galveston, and surrounding areas through Sunday evening, creating conditions that are considered unhealthy for sensitive groups. To help mitigate these levels, residents are encouraged to limit driving or carpool when possible. Furthermore, those planning outdoor activities are advised to restrict them to the early morning or late evening hours to avoid peak pollution times.
