Weather in September
September flags a minute going back in the sea temperature, as it slightly drops to 28.7°C (83.7°F). However, this decrement does not really put a dent on the lingering high temperatures in
Rosignol. The remaining tropical warmth sustains, and the degree of sunlight continues to deterges little by little. The projection for
October suggests the arrival of cooler temperatures and a gradual reduction in daylight hours. September, thus, offers a soft prelude to the ensuing cooler months.
