Houston, Texas – Thunderstorm chances are climbing across Southeast Texas, with rain probabilities peaking at 75% in Houston and Galveston by Tuesday. Coastal boaters face rougher seas and gusts up to 25 knots near the Matagorda Entrance through Thursday, making caution essential for marine travel.
According to the National Weather Service in Houston/Galveston, a pattern of light to moderate onshore winds will bring isolated to scattered storms daily through June 24. Offshore, wave heights of 4 to 5 feet are expected, especially near the 20-mile and 60-mile marine zones.
Galveston and Freeport are likely to see 1 to 2 feet of wave height with increasing storm activity beginning late Sunday. Inland, temperatures will remain seasonally hot, topping out near 92°F in Houston and 95°F in Livingston. Overnight lows will stay muggy in the mid to upper 70s.
Anglers and mariners should monitor conditions closely, particularly around Matagorda Bay and the Freeport channel, where gusts between 20–25 knots and 4 ft surf could pose navigation risks. Use caution when planning offshore trips and delay small craft launches during peak gust periods.
Daily rain chances will persist through early next week, with the highest precipitation threat on Monday and Tuesday. Further advisories may be issued if rainfall intensifies or local flooding becomes a concern.
