Weather by month
Galveston
Texas
An island where the Gulf sets the thermostat — slow to warm in spring, slow to let go in fall, and never out of the wind.
The best time to come
May is the island's sweet spot: warm water, warm air, and as few wet days as the Gulf coast gives you, all before the summer crowds and storm season arrive. April is the calmer version and October the softer one — warm sea, thin beaches, and a weather eye still worth keeping.
