Many South Floridians know that our climate has two seasons: wet and dry. South Florida officially entered the dry season on October 17, 2021—four days later than the historical median date of October 13. Did you know that the 2021 wet season provided an average amount of rainfall in South Florida?

The South Florida Water Management District's water managers keep an eye on the weather 24/7. This is because the Everglades and urbanized South Florida are home to rain-driven systems—nearly all of the surface water we manage comes from rainfall that falls within the District's boundaries.
Weather forecasts and assessments are used by our water managers to help them determine where to move water in our system of canals and water control structures in order to prevent flooding, protect the environment, and meet the region's water needs.
