Blue Hole in March

November through April offers the calmest seas and clearest visibility — sometimes reaching 200 feet. December and January are peak season, so book early and expect higher prices. The trade winds die down during these months, making the boat ride more comfortable and the diving conditions ideal. Avoid May through October if possible — it's hurricane season, seas are rougher, and many operators cancel trips due to weather. But here's a secret: late October can be spectacular if you get lucky with conditions. The crowds are gone and prices drop, but you're gambling with Mother Nature.
