Yes, if the weather does not put you off. September in Fort-de-France is Calm on the typical day, and not one of the 30 days in our window is crowded enough to call Busy. Expect around 31 °C by day, with rain on about 21 days. Public holidays in United States add to it. Cruise ships call on 4 of the 30 days. No week of September is meaningfully quieter — the typical day is Calm throughout; pick by day instead. The crush is at the market rows at group hours; the quiet is at the far shore's beaches. The calmest day is Wednesday 1 September, the busiest Friday 3 September.
In short, quiet and wide open, if the weather doesn't put you off.
