Since it is just a little south from the equator, the climate is tropical. The temperature ranges around 30°C or mid-80's °F. Exposure to the sun directly can be hot for most westerners, particularly in the afternoon. The wet season is between October and March and at this time it can become very humid. However there are frequent downpours that can bring the heat down. The dry season which is from April and September is a better time to visit the island. The coast is hot, but the interiors, particularly the hills can become chilly. So it is best to carry light woolen clothing if you have plans to explore this part.
