The Raja Ampat archipelago straddles the line of the Equator, so its climate is hot and humid. Temperatures are stable throughout the year. The seasons differ mainly according to the rains. The humidity is always very high and always above 80%. The climate is extremely variable among the many islands that make up the Raja Ampat archipelago. Let’s see on this page what is the best time of year to go to Raja Ampat.
Being at the equator, rain can fall at any time of the year. But there is a rainy season that runs from May to September, when the south-east monsoon blows. During this period, most of Raja Ampat’s rainfall occurs. Almost 3,000 mm of rain fall per year.
The wettest months are those of May, June and July, in these months the monthly average exceeds 300 mm. The driest month is February with an average precipitation of 180 mm. It should be noted, however, that, even in the rainy season, the rainfall is unlikely to be continuous. So even in that period there are some days of good weather, moreover the precipitations are sometimes short-lived and localized.
The central part of the rainy season (from mid-June to mid-September) also brings strong winds that cause rough seas. This makes it difficult to navigate between the islands and even to dive. The northern coasts of the islands are more protected at this time of year.
The least rainy period is when the northwest monsoon blows between October and April. But within this period there is another relatively rainy shorter period, which usually includes the months between mid-December and January.
Temperatures are constant throughout the year, the annual average is 27 ° C. The average maximum temperatures are around 30 ° C, while the average minimum night temperatures are 24 ° C. Very high is the humidity which contributes to making the temperatures seem higher than they actually are. The region’s average relative humidity is around 83%. In August it reaches 86%, while the months with the lowest humidity are January and February with 81%.
The surface temperature of the sea water is around 29 ° C all year round.
