Port-au-Prince Weather in May

May's heat and rain

May feels hot and close in Port-au-Prince. Days reach 32°C, nights stay warm, and humidity makes walks feel tiring. Rain falls on 11 days, though there's still some sunshine between cloudy spells.

Plan shorter outings around the shaded galleries of MUPANAH, the Haitian National Pantheon Museum, or a visit to the Iron Market. Long walks across exposed Champ de Mars can feel punishing in the heat. Heavy rain can also make road trips slower, so leave extra time if you're crossing the city.

Flag Day and local life

May 18 is Haitian Flag Day, a national holiday. You may see flags and public celebrations, though events and access can vary from year to year. May 1 is Agriculture and Labor Day, another public holiday.

For families, a museum visit can be easier than a long, hot day outdoors. Keep plans flexible around rain and holiday closures, especially near Champ de Mars, where MUPANAH stands.

Crowds, costs and a local tip

May is quieter than the peak travel months from December to April. You'll generally find fewer visitors and may see lower hotel rates, though local conditions can affect what's open. It's a useful time for a city-focused visit if you're comfortable with heat and some wet days.

At MUPANAH, check locally that the museum and surrounding area are accessible before setting out. Security conditions and opening arrangements can change. The museum is beside Champ de Mars, so avoid assuming that a nearby landmark means every route is clear.
