Seasonal ocean and El Niño outlook
Loading the latest ENSO outlook from NOAA.
What this means for Hawaiʻi: El Niño weakens the 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. Comparable strong El Niño years: 1982-83, 1997-98, 2015-16.
