Flic en Flac or Belle Mare?

Flic en Flac has the stronger January weather balance if you want heat with fewer rainy days. Its daytime average is 30°C, compared with 28°C in Belle Mare, and it has 17 rainy days against Belle Mare's 25. That makes Flic en Flac the better bet for plans that depend on dry weather, though it is not a reliably dry option. Belle Mare's lower daytime temperature may appeal if you find heat tiring, but the catch is more frequent rain. Neither offers cooler nights: both average 25°C after dark, and both have a sea temperature of 28°C, so there is little to separate them for water warmth.

Expect warm evenings and flexible outdoor plans

Pack for warmth that continues into the evening rather than a marked cool-down after sunset. With nights averaging 25°C, light clothing is likely to be more useful than heavy layers, while a lightweight waterproof is a practical addition for wet spells. Average sunshine of 5.2 hours means January is not simply a choice between heat and rain: there is sunshine too, but do not build every day around clear skies. Keep outdoor plans easy to rearrange and allow yourself shade breaks in the midday heat. The 28°C sea should feel warm rather than brisk, which suits travellers who dislike a chilly swim.
