Never mind the fact that Ecuador is located on the Equator, the Ecuador weather is mostly affected by the altitude and the proximity to the Equator. The coastal regions and the Amazon Basin are hot and humid almost all year round. Especially the wet season from December through March can be very hot and wet at times. The highlands are mostly influenced by the altitude. The sun can be very strong and bright during the day but as the night falls temperatures will always drop quite a bit, creating the typical highland extreme weather. In general the whole of Ecuador knows two seasons the wet and the dry season. The wet season runs from December through April and the dry season from May through November.
