The Best Time to Visit Grenada
Between late November and December is the best time to visit Grenada. The temperature is warm with averages around 75-80 (24-27 Celsius) and there aren't too many crowds as the high season is just commencing. At the end of November you may experience a few rainy days; but they're infrequent and don't last long. Lodging and flight prices will also be less expensive during these months.
Between January and April is the most popular time to visit Grenada. The temperature is hot with averages in the mid 80's (around 29 Celsius). Everything on the island will be in full swing but this is the high season so hotels and activities will be at their most expensive. Additionally, there will be crowds throughout the popular destinations on the islands.
Between May and mid-November crowds go down and some hotels will be closed as the country begins preparing for hurricane season which lasts from July until September. That being said, some hotels in Grenada are still open with extremely reduced rates: but if you choose to travel during this time you should expect a lot of rain along with fauna in its prime. If you travel, especially during these months, it's highly recommended that you purchase travel insurance for any emergencies.
