Pacific Island Sea Level Forecasts

This experimental product provides an outlook of monthly sea level anomalies for the next one to two seasons. Users click tide gauge locations around the Pacific to view forecasts, tide charts, and potential impacts. The site combines sea level forecasts with astronomical tide predictions to provide more accurate predictions of coastal water level compared to tide predictions alone.

The tool shows a discussion of current conditions, outlooks for sea levels over the next six months, and an analysis of sea levels over the past six months. 

NOTE: This seasonal forecast product is experimental. For Six-Day High Sea Level Forecasts, please see the High Sea Level Forecast for your region. Neither the seasonal nor the weekly product is accurate when a tsunami or tropical cyclone threatens your coastline.
