Regional Climate Variations
Port-au-Prince Lowlands
The capital region embodies Haiti's classic tropical savanna climate (Aw), with average temperatures around 28°C year-round. Summer highs reach 35°C from June to August, while winter averages 27°C with lows rarely below 24°C. Annual rainfall totals 1353mm, concentrated in the wet season (May-November), leaving a pronounced dry period ideal for beach activities. High humidity and hyperoceanic conditions mean consistent warmth, but heat index can feel oppressive. Expats appreciate the reliable sunshine (over 2500 hours annually) for coastal living, though urban heat islands amplify discomfort.
Consistently warm and sunny with steamy wet seasons and comfortable dry winters, perfect for year-round outdoor lifestyles but demanding acclimation to humidity.
Northern Plains and Mountains
Northern regions receive heavier rainfall on mountain slopes, transitioning from tropical savanna to wetter conditions. Temperatures mirror lowlands at 25-32°C but cool slightly with elevation. Wet seasons bring high precipitation, supporting lush vegetation, while dry periods affect agriculture. Heavier rains from April-June and August-October foster fertile plains but increase flood risks. Ideal for nature enthusiasts seeking greener escapes from coastal heat, with trade winds providing some relief.

Southern Peninsula
The southern peninsula, including areas near Les Cayes, experiences abundant rainfall and humid tropical conditions. Temperatures range 25-34°C, with wet seasons delivering moderate to high precipitation. Elevation in Massif de la Selle creates subtropical highland pockets with averages around 16°C at 1400m, where frost occurs in winter. Rich biodiversity thrives in evergreen forests, appealing to eco-tourists. Residents enjoy warm days but must prepare for intense rains and potential hurricanes.

Northwest Peninsula and Gonâve Island
These leeward, drier zones receive low rainfall under 700mm annually due to mountain rain shadows. Temperatures stay warm at 26-33°C with less humidity than wetter areas. Extended dry seasons support semi-arid scrub vegetation like cacti and acacias. Ideal for sun-seekers avoiding frequent rains, though droughts pose water challenges. Gonâve's isolation enhances its arid, breezy appeal for expats seeking quieter island life.
Sunny and arid with gentle trade winds, providing dry, comfortable escapes from mainland rains and a Mediterranean-like dryness.
Haiti's tropical savanna climate offers year-round warmth with temperatures rarely below 24°C, varying by elevation and rainfall from dry northwest zones to wetter southern and northern regions. Expats enjoy abundant sunshine and coastal vibes but should prepare for hurricane season, high humidity, and water scarcity in arid areas. Highland retreats provide refreshing cooler options amid the tropical heat.
