Trinidad and Tobago has a maritime tropical climate. There are two seasons annually: the dry season for the first five months of the year, and the rainy season in the remaining seven of the year. Winds are predominantly from the northeast and are dominated by the northeast trade winds. Unlike many Caribbean islands Trinidad and Tobago lies outside the main hurricane alleys; nevertheless, the island of Tobago was struck by Hurricane Flora on 30 September 1963. In the Northern Range of Trinidad, the climate is often cooler than that of the sweltering heat of the plains below, due to constant cloud and mist cover, and heavy rains in the mountains.
