Summer convection drives Brownsville's precipitation: September logs 6.7 inches on 29.1 rainy days, against February's 1.8 inches on 16.5 — warm-season storms carry Brownsville's moisture. That puts Brownsville in a summer-convective cohort with places like Gladeview, FL, West Little River, FL and Miami Springs, FL.

Brownsville rarely sees a hard freeze — its coldest month sits near 69°F — so planting spans most of the calendar. Heat peaks in August around 83°F, which confines cool-season crops to the shoulders of summer. Brownsville's coastal lots stay 4-7°F milder overnight than Brownsville's inland parcels.
