Increases hurricane risk near Hawaiʻi
Potential Super El Niño, elevated risk
ENSO-neutral conditions returned in May 2026 and NOAA has issued an El Niño Watch. The subsurface Pacific is running warmer than the same point in the 1997-98 or 2015-16 events, and ECMWF's May ensemble has converged near a peak Niño-3.4 anomaly of +3°C by November, which would rival or exceed the strongest events on record. NOAA gives a 96% chance El Niño persists through December–February.
What this means for Hawaiʻi: El Niño weakens trade winds and warms the central Pacific, favoring more tropical storms and hurricanes near the Hawaiian Islands. The 2015-16 super El Niño brought a record 16 Central Pacific storms (about three times the long-term average), and the first time any ocean basin held three Category 4 hurricanes at once.
Don't wait for a hurricane, stock up, plan, and know your zone
