Being near the equator, and with two thirds of the country being rainforest (one of the oldest on the planet) when it rains here, it really rains. It's humid all year round and the average rainfall per year is 250cm !! In fact the wettest area can have over 400cm per year, with it raining 250 days of those days. It's too hot for raincoats, so umbrellas is the big business here, being used for both rain and sun shade.
