Rain season
Houston is one of the wettest US cities, averaging 1,270mm annually, with rain possible in every month. Summer produces powerful afternoon convective thunderstorms, while Gulf tropical systems August–October can bring catastrophic multi-day rainfall. The city's flat terrain and clay soil make flooding the primary hazard — even moderate rain can overwhelm drainage.
