Most of Cuba has a tropical savanna climate (Aw according to the Köppen climate classification), although areas on the windward slopes of the Sierra Maestra and Sierra del Rosario have either a tropical monsoon climate or a trade-wind tropical rainforest climate, whilst a hot semi-arid climate occurs in the Guantánamo Bay area because of a rain shadow from the Sierra Maestra. In most areas, the dry season lasts from November to April and the rainy season from May to October.
