Climate in the Philippines is mainly divided into two seasons: wet and dry. The dry, cooler season usually begins on November and ends on February. The dry, warmer period is from March through May. During the wet season, he summer monsoon brings heavy rains to most of the archipelago usually from June to October, whereas the winter monsoon brings cooler and drier air from December to February. Manila and most of the lowland areas are hot and dusty from February to May. Even at this time, however, temperatures rarely rise above 37 °C (99 °F). Mean annual sea-level temperatures rarely fall below 27 °C (81 °F). Annual average rainfall ranges from as much as 5,000 millimetres (200 in) in the mountainous east coast section of the country to less than 1,000 millimetres (39 in) in some of the sheltered valleys. Monsoon rains, although hard and drenching, are not normally associated with high winds and waves. But the Philippines sit astride the typhoon belt, and the country suffers an annual onslaught of dangerous storms from July through October. These are especially hazardous for northern and eastern Luzon and the Bicol and Eastern Visayas regions, but Manila gets devastated periodically as well (see Wikipedia – Climate of the Philippines for more information).
