Houston Climate

Humid subtropical climate. Hot, humid, and wet for much of the year. Summers are brutal (33–38°C) with high humidity and near-daily afternoon thunderstorms. Severe storms with hail and high winds regularly cause ground stops from April through September. Houston's flooding risk is significant. Heavy rain events, including tropical system remnants, have flooded airport roads, cutting off surface access even when the airport itself remains operational.

Winters are mild (5–18°C) with occasional ice storms. These are rare but highly disruptive when they occur. Hurricane season (June–November) requires monitoring for Gulf storms. October through March has the best flying weather.
