Haiti’s dry season is from November to March, which with lower humidity and less rainy days, is the best time for snorkeling, hiking, and other outdoor activities. Dry season is also peak travel season, so keep that in mind. It just depends on your itinerary and budget. I traveled to Haiti in the summer, and it was very hot. You get used to sweating with the temperatures, hot summer sun, and the humidity. It’s vital to stay hydrated and bring as much quick-dry clothing as possible.
