Saint Lucia enjoys a tropical climate with consistently warm temperatures year-round, ranging from highs of 84-87°F and lows of 73-77°F. The island experiences two distinct seasons: a drier period from January through May with rainfall between 3.0-4.9 inches monthly, and a wetter season from June through December when precipitation increases significantly, peaking at 10.2 inches in October. Humidity remains steady at 70% throughout the year, while trade winds provide natural cooling. The wettest months (July through November) coincide with the Atlantic hurricane season, though Saint Lucia's southern Caribbean location means it's less frequently affected than northern islands. The driest and most comfortable period occurs from February through April, making this the peak tourist season.
