Through
cooperative arrangements with South American institutions, the TOGA
program has maintained a network of nine tide stations and four
meteorological stations in Ecuador, Peru and Chile since the mid
1980's. The stations are maintained by NOAA/AOML and the University of
Hawaii. The hourly data are transmitted to down-link stations via the
GOES satellite in real time and processed. The five-day averages
(pentads) at critical stations give us an effective means of monitoring
coastal conditions with good time resolution and compact data volume.

Except for the sharp rises associated with intraseasonal
wind events, which are typical at this time of year, sea
levels and SSTs continue below normal. However, present
levels are not as anomalous as the low levels experienced
during the first La Niña phase in 2007.
