The Best Time to Visit the Tobago Cays
Just like most Caribbean islands, the best time to visit the Tobago Cays is during the shoulder months for the less expensive prices and considerably fewer crowds. The best time to visit St. Vincent des Grenadines is between May and June for just that reason.
Between July and October is the off-season in the Cays that corresponds with hurricane season in this area. Tropical storms are at their height in July and they'll last until October but the landscape of these islands is majestic and your trip will be considerably less expensive.
November, at the tail end of hurricane season, is an excellent time to visit for those wanting to save some money but not sacrifice the sunny experience. This is a shoulder season as the Cays begin preparing for the upcoming busy high season.
Between December and April is the peak tourism season on these islands and can be a good time to go. Hotel rates and crowds will be at their height but the weather is perfect and this can be a nice break from the winter season depending on where you're coming from
