Plan your stay: enjoy a dry climate, 24°C sea temperatures and whale watching for a memorable trip to Mauritius in September.
Mauritius in September marks the end of the austral winter, which is excellent news for your trip. The weather remains dry, daytime temperatures are mild at around 25°C, and the sea reaches 24°C. It is also the height of the whale-watching season off the west coast. Looking for sunshine without the tropical humidity? Here is everything you need to know about the weather, the top activities and our tips for making the most of your stay on the island from Legend Hill.
In September, Mauritius enjoys dry and mild weather, typical of the end of the austral winter.
Daytime temperatures range between 22 and 28°C, while morning lows can drop to around 18°C. The waters of the Indian Ocean remain pleasantly warm, averaging 24°C and making them ideal for swimming.
According to the Mauritius Meteorological Services, the island experiences a cool, dry winter from June to September, in contrast to the hot and humid austral summer. Rainfall decreases significantly, falling below 50 mm on the west coast, which is better sheltered from the trade winds.
These climate averages vary little from year to year. With more than 8 hours of sunshine per day, the skies remain bright, allowing you to make the most of your trip to the island!
September is considered one of the best times to visit Mauritius, and for good reason.
First, the dry weather reduces the risk of unexpected rain and leaves your days free for excursions. September also falls before the busy year-end holiday period, meaning visitor numbers remain relatively moderate and attractions can be enjoyed at a more relaxed pace.
In addition, the end of the austral winter brings excellent conditions both at sea and on the hiking trails. The soft seasonal light enhances the turquoise lagoons and the dramatic landscape of Le Morne Brabant, a UNESCO World Heritage Site.
For a trip to Mauritius in September, you therefore get a combination of pleasant weather, abundant nature and a peaceful atmosphere.
September also marks the return of some of the island’s major festive events. Wind enthusiasts are in for a treat, as the southeast trade winds provide some of the most reliable kitesurfing conditions of the year at Le Morne. Remember to book your sea excursions in advance, as whale-watching season attracts many enthusiasts to the Mauritian west coast.
In Mauritius in September, outdoor activities take centre stage thanks to the dry weather and inviting sea temperatures. There is plenty to choose from, from water-based activities to hiking trails, with the west coast around Tamarin and Le Morne offering some of the season’s most memorable experiences. Here is a quick guide to the highlights you can plan during your stay:
Culture enthusiasts can also visit Port Louis, the capital, which is less than an hour’s drive away.
The Mauritian west coast, home to Black River, is the region best suited to a September getaway. Better sheltered from the trade winds than the north or the higher inland areas, it enjoys a warmer and drier climate, perfect for making the most of the beaches and lagoon.
It is precisely here, on the hills of La Tourelle, that our Legend Hill property offers 180° views over the turquoise lagoon and Le Morne Brabant.
Just a few minutes from Tamarin, our location puts whale-watching excursions, kitesurfing and hiking trails within easy reach. The sustainable cuisine of three-Michelin-starred Chef Glenn Viel, based on locally sourced ingredients, extends the experience after a day at sea. For a trip to Mauritius in September, this west-coast location makes all the difference.
September is the perfect time to combine mornings at sea with evenings watching the sunset. Our guests often leave with the memory of spotting a whale from the boat off the coast of Black River.
