Grenada is a small volcanic island in the Caribbean's Lesser Antilles, green with rainforest, spice plantations and waterfalls, with Carriacou and Petite Martinique to the north. Grand Anse beach, the nutmeg and cocoa estates behind the Spice Isle name, and the underwater sculpture park near St George's round out the island's best-known places. The dry season from December to May is the most reliable, while the wetter months are hotter and storm-prone.
Warmest month: September (28°C). Wettest: July (143 mm). Best overall score: February (7.4/10).
