Climate overview
Haiti occupies the western third of Hispaniola between about 18° and 20°N in the Greater Antilles, covering approximately 27,750 km² and sharing the island with the Dominican Republic to the east. The terrain is dominated by a rugged mountain backbone including the Massif de la Selle rising to Pic la Selle at 2,680 m (the country's highest peak), the Massif de la Hotte with Pic Macaya at 2,347 m, the Chaîne des Matheux, the Massif du Nord, and the long Tiburon southern and Nord-Ouest peninsulas separated by the Gulf of Gonâve.
The Plaine du Cul-de-Sac, a low depression in the southeast, adjoins the capital Port-au-Prince, which lies near a major strike-slip fault. The climate is tropical maritime, wetter on the windward northern and eastern slopes, with subtropical highland Cwb in the high mountains.
Port-au-Prince sees January highs of about 31°C and July highs of about 34–35°C, with 1,350 mm of rainfall concentrated in two seasons from April to May and August to October. Cap-Haïtien on the north coast and Jacmel in the south share the tropical climate of the lowlands.
The high mountain interior is significantly cooler: Kenscoff, at about 1,500 m in the hills above Port-au-Prince, has a subtropical highland climate, constantly cooler than the capital and chilly in the winter months. The Cul-de-Sac valley is drier than the windward mountain slopes.
Haiti sits squarely in the Atlantic hurricane belt and has been struck repeatedly by severe storms and floods, including Hurricane Hazel in 1954, the May 2004 floods, Hurricane Jeanne in September 2004 that inundated Gonaïves, and the Category-4 Hurricane Matthew in October 2016 that made a direct hit on the Tiburon Peninsula, killing hundreds of people. Severe deforestation has worsened floods and landslides, while droughts and depleted coral reefs are central climate concerns.
