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 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.
