Port-au-Prince weather in September

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.

Forum posters describe January as sitting within Port-au-Prince's driest stretch of the year, with December and January each seeing around six inches of rainfall - genuinely the least rain of any two-month period. Posters note temperatures stay warm essentially year-round here, with average lows just below 70F and average highs just above 85F showing relatively little seasonal swing compared to many destinations. Posters generally frame January as a good pick from a pure weather standpoint, combining the year's driest conditions with consistently warm temperatures, though posters' broader discussion of Port-au-Prince tends to focus heavily on safety and logistics given the security situation.
