Situated in the Caribbean Sea, Grenada has a tropical climate with northeast trade winds that have a cooling effect. Notably the temperature changes with altitude and as you get to the center and the mountains, you will feel a significant drop. The average year round weather in Grenada is around 80°F, with daytime highs reaching 86°F and getting down to 75° at night. The warmest period is between June and August; while November to February sees the trade winds come into effect.
The rainy season falls between June and November, where the air can feel muggy and heavy rainfall is imminent along with heavy winds.
