Brenham's location near the Gulf of Mexico means it gets humid air from the southeast, which increases air pressure. The city's flat terrain doesn't block winds, so air pressure can change quickly. In spring and summer, warm air rises, lowering pressure and bringing thunderstorms. In fall and winter, cool air sinks, increasing pressure and making the weather calmer. Brenham has a humid subtropical climate, which means it experiences extreme pressure changes between seasons, leading to varied weather.
