Saint Lucia in December

December through May delivers the sweet spot — dry weather, trade winds, and temperatures in the low 80s. But everyone knows this, so expect crowds and peak prices. January and February are particularly busy with snowbirds. Hurricane season runs June through November, with September and October seeing the most action. But here's the thing — Saint Lucia sits south of the main hurricane belt, so direct hits are rare. The shoulder months of May and November offer the best deals. You might catch a shower, but it usually passes in 20 minutes. Avoid September if possible — that's when humidity peaks and some restaurants close for maintenance. The Christmas weeks book solid by October, so plan ahead if you're coming for the holidays.
