Season planner for Grenada (St. George's and Grand Anse)
Grenada is diveable year-round, but the trip style changes with the weather. The driest months usually run from December to May, which is best for mixing boat diving, beach time, and hilltop sightseeing. Rainier months from June into November keep the island lush and the water warm, but tropical systems and runoff can affect visibility and day-to-day planning. Because St. George's and Grand Anse sit on the leeward southwest coast, many of the easiest reef and snorkel options remain viable more often than exposed Atlantic sites.
