Read the numbers correctly
Climate, not a promise.
These patterns help compare months. They cannot tell you the weather on a specific day of your trip.
Sources, method and limitsHow these numbers are made (what the highs, lows and rain days mean, the sources and the model cell used for Port-au-Prince) is explained once on the Port-au-Prince year overview and on the Sources, method and limits page.
Pétionville, Cité Soleil and Croix-des-Bouquets lie in the same rainfall cell, so their rainfall figures are identical to these; temperatures differ because they come from smaller 0.1° cells.
