The climate in the archipelago of Palau (or Belau) is equatorial, that is, hot, humid and rainy throughout the year. In fact there is no real dry season, but only a relative decrease in the frequency of showers and thunderstorms between February and April.
In the capital Ngerulmud (or Melekeok), the daytime temperature is around 30/31 °C (86/88 °F) all year round, while at night it's around 23/24 °C (73/75 °F).
Here are the average temperatures.

The rains are plentiful, and amount to around 3,600 millimetres (140 inches) per year; the rainiest months are those of summer (June, July and August), even though we cannot speak properly of summer, because the temperature is stable throughout the year.
Here is the average precipitation in the Airai airport.

The amount of sunshine is acceptable from February to May, and lessens a bit from June to December, when showers occur almost daily, however, the sun almost always shines for a few hours a day, except during the passage of typhoons (see below).

Palau can be hit by typhoons, ie tropical cyclones of south-east Asia, which pass over the country, and then make their way to the Philippines. Typhoons, along with the less intense tropical storms, bring rains and strong winds, and normally occur between May and December, though they are more frequent between August and November. The south-western islands (states of Sonsorol and Hatohobei), being near the equator, are protected from typhoons, or at most they may be affected marginally.


The best time to visit Palau runs from February to April, being the least rainy and the sunniest of the year. Even in this period, however, showers and thunderstorms must be put into account, but they they do not last long, so they soon give way to the sun.


All year round, tropics-friendly, loose fitting clothing, sun hat, a scarf for the breeze, a light sweatshirt for the evening, light raincoat or umbrella.
For the reef, equipment for snorkeling, water shoes or rubber soled shoes.
