Traveller notes on Nosy Be in January
Other months in Nosy Be
Nosy Be's forum calls June one of the cooler, drier months in Madagascar — regulars say the water is swimmable but comfort varies by how used you are to warmer seas, since it's noticeably less balmy than the peak of summer. It also marks the start of the island's high season, so booking ahead is worth it.
