PEAC’s Seasonal Rainfall and Sea Level Outlooks
Every month, the Pacific ENSO Applications Climate (PEAC) Center in Honolulu produces a Seasonal Rainfall Outlook and a Seasonal Sea Level Outlook for Hawai‘i and the U.S.-Affiliated Pacific Islands.

PEAC’s Seasonal Rainfall Outlook is an experimental consensus forecast. The PEAC Outlook uses data from 7 models (UKMO, NASA GMAO, ECMWF, IRICP, NCEP Constructed Analog, NCEP Coupled Model, UH/IPRC PRIDE and APCC MME) to produce a probabilistic forecast rainfall for the upcoming three months for 14 locations throughout Hawai‘i and the USAPI.
The Seasonal Sea Level Outlook gives a forecast for the average and maximum sea level anomaly for the current three-month period and the monthly anomaly observed in the previous period.
