Flic en Flac or Belle Mare?
Flic en Flac has the stronger weather case in May: it is slightly warmer and has substantially fewer rainy days than Belle Mare. Expect daytime averages of 27°C and 5 rainy days in Flic en Flac, compared with 26°C and 15 rainy days in Belle Mare. That makes Flic en Flac the more practical choice for a holiday built around swimming and spending time outdoors. Belle Mare still offers warm weather, but suits travellers who are happy to keep plans flexible around rain. Evenings are equally warm at 22°C, so the meaningful difference is the chance of wet weather rather than what you will need to wear after dark.
What to pack and how to plan your days
Pack mainly light clothing, swimwear and sun protection, with a light waterproof for wet spells. Mauritius averages 10 rainy days in May, so allow some flexibility rather than counting on dry weather throughout your stay. Average sunshine of 6.7 hours leaves room for time outdoors, but does not mean every day will be clear. Keep shade and breaks in mind around midday, especially if you find warm weather tiring. With nights averaging 22°C, heavy evening layers are unlikely to be useful; a light extra layer is a more practical option if you tend to feel cool. Plan around the weather on the day rather than assuming rain will arrive at a particular time.
