League City has roughly 32,000 owner-occupied homes, or 74.4% of households. Homes here have a median value of $334,000 and households a median income of $119,870.

Between 2020 and 2025, NOAA's Storm Events Database logged 7 hail days and 17 days with damaging thunderstorm winds in Galveston County. The largest hail reported was 2.75 inches across.
