Climate in Mauritius
Mauritius is an island nation in the Indian Ocean, with the main island of Mauritius and a number of other smaller islands. The main island of Mauritius is roughly 1800km from the African mainland. Due to Mauritius’ location in the southern hemisphere, the seasons are opposite to ours. This means that in the months of November to April, it’s summer and from May to October, it’s winter time in Mauritius. Its location in the Indian Ocean ensures a tropical oceanic climate in Mauritius. For one thing, it means that there are only small temperature fluctuations from month to month. On the other hand, the trade winds blow all year round. The trade winds from the south cool the constantly high temperatures on the island and makes it pleasant for tourists. In summer, the average temperatures are between 25 and 30° C. During this time, there are more rain showers and the risk of tropical cyclones is extremely high. This is especially the case in January and February. So, for your own safety I recommend at this time you should not travel to Mauritius. If you’re wondering when is the best time to visit Mauritius, you’ll get the answer now.

In the Mauritian summer time, the months of November to April, it is much warmer and more humid. The temperatures are on average at 30° C and higher. Likewise, the water temperature in the Indian Ocean is higher. A water temperature between 26 and 28° C offers little chance to cool down. Furthermore, the number of monthly rainy days during this time is a lot higher. There are two to a maximum of five rainy days. In February, for example, there are nine possible rainy days. Compared to the winter time the sun shines longer, the sunshine hours are between seven and nine hours per day. The minimum temperatures at night are rarely below 20 degrees. So, a holiday in the months from November to April is still ideal. Although the rain probability and frequency is higher, the tropical rain means no continuous rain, so you will have a few days of a break. The rain comes in short, heavy showers and then there is another sunshine to look forward to. A special natural phenomenon like this ensures holidaymakers like to avoid the island during the months of November to April. It’s the season of cyclones. What that is and what it means, you will learn a little later.
Best time to visit Mauritius
To make a general suggestion on the best time to visit Mauritius is difficult. For Europeans, the winter time in the southern hemisphere is considered the best time to visit Mauritius . In the months of May to October there are pleasant temperatures, the number of rainy days is minimal and the humidity is lower than in other months. On average, the maximum temperatures are between 25 and 30° C. At night, the temperatures cool down and are between 17 and 21° C. The daytime temperatures are ideal for lying on the beach or visiting the sights of the island, and water temperatures are just as pleasant. Although the temperatures of the Indian Ocean are consistently high throughout the year, they do cool slightly during the Mauritian winter. From May to October the water temperatures range between 24 and 27° C. During their summer time you don’t have to be worried about a lot of rain. Compared to the other months, the least rain falls in June, July, August, September and November. You have to expect a maximum of two to four rainy days during the southern winter months. Due to the good weather conditions in the months of May to October, the winter season is considered the peak season in Mauritius . In these months, weddings, honeymoons and the prices for other trips are much more expensive than in the low season. If you want to avoid the expensive high season, you can choose the months of September to November and March to May. Many families use the Easter holidays for a trip to the island. In this way, you still get the hot temperatures, but you do also spend less money.
Cyclone season in Mauritius
Cyclones are tropical storms, and they can affect Mauritius from November to April. Their formation depends on the water temperature and the position of the sun. In the Indian Ocean, which surrounds Mauritius, a large body of water heats up to over 26° C. This is because in this part of the world, the sun is pretty much vertically above the sea. From 26° C, the upper water layer evaporates faster than the lower one. This leads to so-called cloud towers, which can become extremely high. The rotation of the earth causes these cloud towers to set in motion, and this forms a cyclone. The consequences of these cyclones? Power failures occur at high speed, and in some cases there can be torrential rain and floods. In the Mauritian summer time (from November to April) the cyclone risk is increased. But that doesn’t mean that a cyclone is formed when you are on the island during those months! Many of the cyclones don’t actually come to the island. Instead, they strip them, which can lead to increased waves and clouds, for example.
Weather in Mauritius – regional differences
The general rule for the weather in Mauritius is the temperatures are similar, constant and high over all months. There are some regions on the island deviating from the average though. In Mauritius there are heights of the summits of the Piton de la Petite Riviere Noire, Pieter Both and Le Pouce. At these altitudes, the weather in Mauritius differs from the coastal regions. In the mountains it is on average 5° C colder than on the coast. Instead of the average 23° C, you should instead expect temperatures of about 19° C in the mountain areas. In higher altitudes, the humidity is about 90-100%, and it rains much more often. On the coast there is a humidity of about 70%, which is still high, but much more bearable than in the mountains. The mountains of the island also affect the weather on the coasts. For example, the mountains protect the west coast from rain. On the east coast, on the other hand, the Passat has great influence and it falls more rain. Another difference is the slightly higher temperature of the west coast compared to the east coast year on year.
My opinion on the best time to visit Mauritius
For many travel destinations with a tropical climate, the best travel time has to be decided by everyone. The same applies to the best time to visit Mauritius. Basically, I recommend a holiday on the island in the Mauritian winter in the months of May to October. Then, you can look forward to temperatures we could dream of in our summer. The swimming and sports activities in the Indian Ocean such as surfing, diving and snorkelling are a delight thanks to the pleasant water temperatures. In addition, you run less risk that you’ll run into surprise tropical rain showers and cyclones. For those who can live with a higher rain probability, summer time on the island is a suitable and affordable alternative. For the seasons: The summer is hot and humid, the winter is dry and cooler. You can spend a beach holiday in Mauritius all year round. You’ll definitely have fun on your Mauritius holiday, whatever the season may be.
