How the weather changes through the year
January to March combines hot days with warm nights and sea temperatures of 28°C. The catch is frequent rain: January averages 21 rain days, easing to 18 in March, so leave room to rearrange outdoor plans. April marks a shift towards cooler, less rainy conditions, which becomes clearer in May. June to September is the cooler, less rainy stretch, with daytime temperatures of 24°C to 25°C and nights around 20°C to 21°C. Pack a light layer for evenings rather than relying entirely on beach clothes. October starts the warming trend, while November and December bring increasing heat and more frequent rain.
Flic en Flac or Belle Mare?
Flic en Flac is the warmer choice across the year, averaging 27.4°C during the day compared with 26.2°C in Belle Mare. That is a modest difference, so the month you travel is likely to matter more than choosing between these destinations. If you like extra warmth for lounging outdoors, Flic en Flac has the edge; if you prefer slightly cooler daytime conditions, Belle Mare is the better fit. Do not take that temperature difference as a promise of fewer rainy days or warmer swimming water. The monthly pattern gives a useful broad guide, but it does not establish those differences between the destinations.
When to go for beaches or city time
For a beach-focused trip, May and June are good compromises: the sea remains at 26°C and 25°C respectively, while rain is less frequent than at the start of the year. November is another option if you want hotter days, with 28°C air temperatures and a 25°C sea, though rain becomes more frequent. For city walking and other time on foot, June to September offers a more comfortable temperature range than January to March. Treat that as a seasonal guide rather than a city-specific forecast. In the hotter months, favour mornings for active plans and keep midday flexible for shade or an indoor break.
