Average maximum hourly sea level relative to mean sea level for Apia.

Much of the population of Samoa lives on low lying coastal areas, and is vulnerable to extreme high tides, storm surges, and other coastal hazards.
A Climate Risk Profile (CRP, see reference) prepared for Samoa in 2007 describes a number of present and future climate risks to Samoa, among which are:

an observed average sea level rise of 5.2 mm/year, and
an observed average maximum hourly sea level rising ata rate of 8.2 mm/year.

Monthly SOI values (click to enlarge).

La Niña conditions have continued to weaken during May, and overall the tropical Pacific ENSO indicators are close to neutral, although some remnants of La Niña persist. A positive subsurface temperature anomaly persists west of the Date Line, and a new positive anomaly has developed near South America above 100 m. The SOI eased further in May and became slightly negative at –0.5, with a 3-month March to May mean of +0.4.
