September weather forecast
Grenada

September in Grenada is characterized by its position deep within the rainy season. Rainfall levels during this month remain high, particularly on the windward mountainsides, which receive more precipitation than the lowlands. Despite this increased rainfall, the tropical warmth of the island persists. Daytime temperatures generally oscillate between 26 to 32°C (89.6°F), while nighttime temperatures range from 19 to 24°C (75.2°F). These stable temperatures provide a consistent, comfortable climate amidst the rainy season.

As in other months of the rainy season, rainfall in September often comes in the form of short, intense showers, followed by periods of sunshine. This pattern allows for a continued enjoyment of outdoor activities, albeit with some consideration for the frequent showers.

Variations in weather conditions across Grenada during September are minimal. Coastal regions, such as St. George's, generally experience slightly warmer temperatures due to the sea's influence, while the mountainous regions present slightly cooler temperatures due to elevation.

Importantly, September also falls within the Atlantic hurricane season. Although hurricanes and tropical storms are not common in Grenada, the risk of these events is heightened during this period.

As September transitions into October, the rainy season in Grenada continues, with high levels of rainfall expected. Despite the elevated precipitation, the temperature range remains consistent, preserving the island's characteristic tropical warmth.
