Galveston in August is one of the steamiest months on the island, with average temperatures often reaching highs of 90 and lows of around 80, accompanied by refreshing sea breezes. This is a great month for beach and water park days, as long as you stay hydrated, wear sunscreen, and take breaks in the shade.
