Over the past two decades, coral bleaching has been occurring more intensely and frequently on Florida’s Coral Reef. During summer 2023, extreme ocean temperatures driven by El Niño–Southern Oscillation caused widespread coral bleaching and mortality on some coral species. Ocean temperatures remained globally elevated throughout 2024 and we experienced the 4th recorded global coral bleaching event, which likely ended mid-2025.
Since 2023, the FCRRP has collected lessons learned from practitioners, managers, researchers, and partners on effective and ineffective bleaching response strategies. These insights are being used to strengthen preparedness, coordination, and response planning across the region. In an effort to provide a more coordinated and proactive approach to thermal stress preparedness, communication, operational readiness, and response support ahead of anticipated El Niño conditions, the FCRRP is currently drafting a Thermal Stress Preparedness and Response Plan, soon to be linked below.
El Niño conditions are here, as shown by above-average sea surface temperatures (SSTs) across the central to eastern equatorial Pacific Ocean. Conditions are expected to strengthen into the Northern Hemisphere winter 2026-27, with peaks in October - January.
There is currently a Bleaching Warning in the Keys.
The current alert is expected to remain for the next one to four weeks (July).
A Bleaching Alert Level 1 is expected in five to 8 weeks (August).
A Bleaching Alert Level 1 is expected in nine to 12 weeks (August/September).
There is currently a Bleaching Warning in the Southeast Florida
The current alert is expected to remain for the next one to four weeks (July).
A Bleaching Alert Level 1 is expected in five to 8 weeks (August).
A Bleaching Alert Level 1 is expected in nine to 12 weeks (August/September).

To Learn More About Marine Environmental Monitoring
FWC's Disturbance Response Monitoring Program (DRM) - annual surveys conducted during peak bleaching months (Aug-Oct) on randomly selected sites along Florida’s Coral Reef. Collects data on coral density, diversity, size, and condition of stony corals, including capturing disease and bleaching prevalence. This is the predominant source of data for bleaching corals in Florida.
FWC's Coral Reef Evaluation and Monitoring Project (CREMP) and Nova Southeastern University's Southeast Coral Reef Evaluation and Monitoring Project (SECREMP) - SECREMP annually surveys 22 sites in Southeast Florida and CREMP surveys 51 permanent monitoring sites in the Florida Keys and Dry Tortugas. Collects data on coral population demographics and health, including diversity, size, and condition of stony corals.
NOAA's National Coral Reef Monitoring Program (NCRMP) - biennial surveys to monitor coral populations, benthic communities, and fish populations.
