Swimming After Rain

Rainfall can wash bacteria, fertilizers, and other pollutants into the ocean through stormwater runoff. The Florida DOH recommends waiting at least 72 hours after heavy rain before swimming, especially near inlets, canals, and river mouths. If it has rained recently in the Miami-Dade County area, use extra caution.
