Year-round, average temperatures hover between 27°C and 29°C, with the hottest months being April and May, when daytime highs can reach 35–36°C. Even during the coolest months, temperatures rarely drop below 22°C at night, and the sea remains invitingly warm, ranging from 27°C to 30°C. The dry season brings abundant sunshine, calm seas, and humidity around 72–78%, making it ideal for outdoor activities and water sports. Days are long, with 7–8 hours of sunshine and up to 12–13 hours of daylight.
The rainy season is marked by frequent, sometimes heavy, downpours – especially from July to September – accompanied by high humidity (85–90%) and lush, green landscapes. Rain typically falls in short, intense bursts, often in the afternoon or evening, leaving mornings relatively clear. The wettest months can see over 500 mm of rain, and the island’s annual rainfall can reach 3,000–4,000 mm. Occasional typhoons may affect the island between October and December. Winds are generally gentle in the dry season (average 3–4 km/h), but stronger during the monsoon. Despite the rain, temperatures remain warm and the sea is swimmable year-round, though rougher waters and reduced visibility can limit some activities during the wettest months.
