This website provides access to a broad range of information related to seasonal climate variability in the Republic of the Marshall Isalnds. It includes a quick-look at current and future conditions for a range of climate indicators, direct access to more detailed outlook-related information from stations and statellites, and products that place this information in a histrorical context. It also includes links to addtional sources of information.

NOAA State of the Ocean

Surface ocean indices (updated week of 21-APR-2024)

dx = slope of linear fit to values over the period of time indicated,
ending at latest value of the index
stdx = standard deviation of dx over the period of the climatology

The above plot is based on the National Center for Environmental Prediction (NCEP) coupled forecast system model version 2
(CFSv2).
Forecasts are from initial conditions of the last 30 days, with 4 runs from each day. Forecast ensembles consist of 40 members from
initial a period of 10 days. The figure shows "normal" conditions as approximated by the mean seasonal cycle, past conditions based on
CFSv2 reanalysis, and future projections from the model forecast. The climatology and anomalies are created using values from 1999-2010.

We remove the recent long-term trend (i.e., model drift or bias) from the prediction (e.g., for forecasts issued in 2017 the 1999–2015 trend is removed).
