when is red tide in florida

Red tide in Florida typically occurs most often in late summer through early fall , often starting offshore and persisting into winter or spring depending on conditions like wind, currents, nutrients, and salinity.

Peak Seasons

Red tide blooms, caused by the algae Karenia brevis , form frequently from August to October along Florida's Gulf Coast. They can last weeks to over a year, subside, then reoccur—such as the notable 2017-2019 event.

• Late summer/early fall: Most common initiation, 10-40 miles offshore before moving closer to shore.

• Winter to spring: Blooms often persist or intensify.

• Year-round potential: Less common outside warmer months, but recent monitoring shows activity in areas like Bay, Gulf, and Franklin counties as of late 2025.

Current Status (Feb 2026)

As of early 2026, FWC continues tracking scattered red tide, with forecasts like ECCO Scientific's model predicting severity up to four weeks ahead (up to 84% accuracy in tests). Check FWC's weekly map for real-time updates: myfwc.com/research/redtide.
