Traveller notes on Port-au-Prince in May

Other months in Port-au-Prince

Forum posters describe Port-au-Prince as staying fairly consistent year-round, with average lows just below 70F and average highs just above 85F, though posters flag real seasonal rainfall and hurricane risk that visitors should weigh alongside those steady temperatures. Posters discussing summer travel to Haiti specifically warn that a week-long July visit will likely include a few severe rainstorms on top of genuinely overwhelming heat and humidity. Posters generally recommend monitoring hurricane season developments for any Haiti trip planned for this time of year, given the real, if not guaranteed, storm risk. Posters generally rate July as hot and storm-prone, workable for a visit but requiring real weather-contingency awareness.
