Mauritius : climate and when to go to Grand baie
If you like the beach, which is our main topic on TropicsBeach, avoid the winter season from June to September, which is a period at low temperatures between 61°F at night and 75°F the day at best, which is little to enjoy the sand and lagoon too cool to savor the fish tank and coral gardens. The month of October corresponds to the French school holidays and offers a good compromise, even if the lagoon is at 79°F / 81°F. The best holiday period in Mauritius is from early November to December 15, everything is perfect, until the temperature of the lagoon at 82°F, then the rains come with rare cyclones that can spoil everything from January to April. The rain is more important on the center of the island but few tourists stay there. It rains more on the east coast than on the west coast. Here are the best places to stay in Mauritius: Flic en Flac, Trou aux biches, Pointe aux canonniers, Grand Baie, Mont Choisy, Belle Mare, Mahebourg, Pointe d'Esny, Morne Brabant and Pereybere. Especially if you are in Mauritius, your mask and snorkel should not stay dry!

Weather uncertainties 2025 to go to Grand Baie ?
When traveling in the tropics as a seaside, rain is not welcome. If you see this indicator, with possible storms, that does not mean that it will rain all day long. When we observe the local rainfall, it is either really zero or very weak. Meteorologists prefer to be pessimistic. So observe below, the skies photographed during a week announced stormy in Asia. It did not rain once. I invite you to integrate this parameter before going to Grand Baie for a good trip to the sun!
