Best time of year to swim

The best time to swim in Mauritius is from November to April, when the waters are warm and the weather is sunny. During this time, the temperature of the ocean averages around 27-29°C, making it perfect for swimming and other water activities.

The sea around Mauritius is characterised by crystal-clear waters, vibrant coral reefs, and a diverse marine life. The island is surrounded by both lagoons and open seas, each of which offers a different swimming experience.

The lagoons around Mauritius are sheltered by coral reefs, which protect the waters from strong ocean currents. As a result, the waters in the lagoons are mostly calm and clear, making them ideal for swimming, snorkeling, and other water activities. These lagoons are also home to an abundance of colourful marine life, including fish, coral, and sea turtles, making them popular with visitors who want to explore the underwater world.

In contrast, the open seas around Mauritius can be more challenging for swimmers. The strong currents, combined with the deeper waters, can make swimming in the open seas quite risky. However, these areas are also home to a variety of marine life, including dolphins, whales, and sharks, making them popular with divers.

Dangers to avoid

Although the waters in Mauritius are generally calm and safe, there are a few dangers to be aware of. There were 43 reported deaths from drowning in Mauritius in 2020 and reports of Stonefish or Jellyfish stings are not rare.

There are no lifeguards on public beaches in Mauritius.

Strong currents

Although the sea may look calm, there are strong, invisible currents in the lagoons and open seas around Mauritius. It’s important to always swim within designated areas and to never swim alone or unsupervised. The Mauritius Beach Authority usually displays a sign indicating the dangers in an area, such as strong currents, heavy swells, boat traffic or open sea.

Swimming conditions in Mauritius can change rapidly and unexpectedly with sudden change in weather and tides. It's a good idea to ask for locals about the safety and characteristics of the particular area where you intend to swim.


The Stonefish is a venomous fish species that can be found in the sea around Mauritius. With its camouflage, resembling a bumpy rock or sand, it blends in with its surroundings. It often lies still and motionless on the sand, rocks or corals making it hard to spot.

Stonefish are highly venomous, and their venom can cause severe pain, tissue damage, and sometimes even death if not treated promptly.

When swimming or walking in coastal areas, wear footwear and avoid stepping on anything resembling rocks or coral.

If stung by a stonefish you must seek immediate medical assistance. Call 112 for SAMU ambulance. Note the time of the sting.

The stonefish is locally called "laffe la boue" in Creole, and "Poisson-pierre" in French.


During certain times of the year, jellyfish can be found in the waters around Mauritius, and they can cause painful stings.

The Box jellyfish is also found in the waters of Mauritius. It is known for its highly venomous nature and painful sting.

If you are stung by a jellyfish in Mauritius, seek medical attention immediately. Call 112 for SAMU ambulance.

The National Coast Guard informs the public through the media whenever there are jellyfish sightings in lagoons. The French-language Defimedia.info website is one among many news websites that inform the public.

How to check for Jellyfish alerts

To see the latest jellyfish alert:

  • Visit www.defimedia.info
  • Search for the term "méduses" (the French word for jellyfish)
  • Refer to the latest articles and check the date and location of the most recent sightings.
  • If you don't understand French, use a translator like Google Translate.

Sea urchins are also quite common in Mauritius and you should avoid stepping on them.

Protecting yourself

It's generally a good idea to wear footwear such as extra sturdy and thick-soled reef shoes/sandals for protection against stonefish and sea urchins. (Thin reef shoes don't provide sufficient protection as stonefish spines pierce through them. Watch a YouTube Video.)
Wetsuits, rashguards, swimming gloves and shoes can reduce chances or severity of jellyfish stings.

Before going for a swim in Mauritius, it is important to check a few key things to ensure a safe and enjoyable experience:

  1. Weather conditions:
    Check for any weather warnings, such as high winds or storms that could make the water conditions dangerous.
    See the Mauritius Meteorological Services website for general weather forecast and look out for High Waves warnings. Ask your hotel if there have been any weather warnings related to the sea.

  2. Tides and currents:
    Check for any strong tides or currents in the area where you plan to swim. Avoid swimming in areas with strong currents or in areas that are designated as off-limits. Ask your hotel or locals about tides and currents in the area.

  3. Check the news for Jellyfish alerts. Ask your hotel or locals if there has been a jellyfish alert in the region where you plan to swim.

  4. Beach conditions:
    Check the beach conditions, such as the presence of rocks or underwater hazards or anything that does not look right, including a lack of bathers where you'd expect. Make sure that you are aware of any signs indicating safe and dangerous areas.
