Guyana's climate is typical of most tropical countries. Humidity ranges from an average low of 68% in October to 77% in May, and an average high of 79% in October to 86% in May through August. The average annual mean (AAM) is 73% in the afternoons and 83% in the mornings. Minimum temperatures in Georgetown, on the coast, range between 22-26°C (71-80°F) year around, with an AAM low of 75. Maximum temperatures range between 28-32°C (83-90°F), year around, with an AAM high of 86. The sea breezes (east-northeast trade winds) significantly mitigate the heat on the coast. The coastal area typically has two wet seasons: May to mid-August, when about 40% of the total annual precipitation falls, and December to mid-January, which receive another 20%. However, occasional rain may fall at any time of the year. Georgetown and the coast average 90 inches of rainfall annually; in the interior, 60-150 inches occur.
