The [[climate]] is [[tropical]]; although it could be classified as a [[tropical monsoon climate]], it could also be described as a climate that is transitional between a continually wet [[tropical rainforest climate]] and a [[tropical savanna climate]].{{sfn|Gabler|Petersen|Trapasso|Sack|2008|p=238}}

There are two seasons; dry season (November{{snd}}May) and rainy season (June{{snd}}October).

December to January are the coolest months of the year, although temperatures can still exceed {{convert|40|°C|disp=or}}, lower to moderate humidity makes the heat around this time of the year more tolerable. Unlike March and April, the months that it gets hot and humid with temperatures around {{convert|33|to|36|°C|°F|disp=or}} and a solid 50% humidity, making the heat index higher than the actual temperature. The average sea temperature is {{convert|30|°C|°F|disp=or}}.<ref name="WFact" />{{sfn|Blinker|2006|p=12}}{{sfn|LeVert|2007|p=8}}

Average rainfall is highest at the coast, {{convert|3000|to|5000|mm|in|-1|disp=or}} per year; moving inland this decreases and at the eastern border of the country, the average rainfall is {{convert|2000|to|2500|mm|in|-1|disp=or}}.{{sfn|Hughes|Hughes|1992|p=435}}
