Monthly SOI values (click to enlarge).
A mature La Niña event continues in the tropical Pacific, and is very likely to persist through autumn 2008. Below normal sea surface temperatures (SSTs) extend across most of the equatorial Pacific, with anomalies of –2.0 °C or more over the central equatorial region (Date Line to 120° W, approximately).
