Residents and beachgoers may experience changes in the typical seasonal timing of shark presence in Florida waters due to global climate cycles.
Key Facts
- NOAA estimates a 95-percent probability that El Niño will become very strong this Fall.
- There is a 69-percent probability that this El Niño will be stronger than most observed since 1950.
- Marine experts are using the term 'Shark Niño' to describe potential shifts in shark migration patterns caused by El Niño.
- El Niño can influence ocean temperatures and food sources, which may delay or alter the timing of shark migrations.
- Hammerhead sharks typically appear in Southern California waters when temperatures reach the mid-70s or during El Niño years.
