Tropical Rainforest Climate Explained
Raja Ampat’s climate is classified as ‘Af’ under the Köppen system, a tropical rainforest climate. Temperatures stay between 27°C and 31°C all year. Humidity is always over 80%, making the islands lush and green.
The heat and humidity lead to a lot of rain, even in dry months. This climate is perfect for the region’s incredible biodiversity. It supports coral reefs and dense rainforests.
Monsoon Seasons and Their Impact
The monsoon is the main force shaping raja ampat seasonal weather. These wind patterns change with the seasons. They create two main periods in the annual raja ampat weather patterns.
The Northwest Monsoon, or wet season, runs from November to April. It brings more rain and rougher seas. Winds come from the northwest, carrying moisture from Asia.
The Southeast Monsoon, or dry season, lasts from May to October. It brings calmer seas, less rain, and more sunshine. Winds come from the southeast, over the Australian continent.
The transition between these monsoons is gradual. It affects diving, wildlife, and travel plans. The exact date of the shift varies.

|---|---|---|
| Primary Period | November to April | May to October |
| Prevailing Winds | From the northwest | From the southeast |
