The Republic of Palau (Belau)

Climate

Palau’s climate is tropical, with a hot and humid rainy season extending from May through November.  The mean annual temperature is 82oF (27°C).  Rainfall averages 150 inches (3,800 mm) a year, with June through August being the wettest months.  There is a drier period between January and April when the average monthly rainfall is 9 inches (229 mm), although at times it can be as low as 6 inches (147 mm).  Additionally, Palau's surface waters average in the low 80°s F (20°s C).

The maximum rainfall is in July. Most rainfall occurs as short heavy showers. Over the land, these showers are most frequent in the afternoon, but over the surrounding ocean area, showers occur most often during the early morning hours. Spells of rainy weather lasting several days occur when typhoon storm centers pass to the north. Typhoons are uncommon in Palau, as the islands lie outside the main typhoon path; nevertheless, during the typhoon season (June through December), it is hit by occasional storms with high winds. Typhoons may occur in any month but are least common from February through April.
