From June to August is the dry season in the mountains and altiplano (Andean plateau) while the wettest months are from December to March. It rains all the time in the hot and humid rainforest, but the driest months there are from June to September. However, even during the wettest months from December to May, it rarely rains for more than a few hours at a time. Along the arid coastal strip, the hot months are from December through March. Some parts of this area see rain rarely, if at all.
