If you’re visiting the island right now, you’ll want to pay close attention to the large swells in Mauritius and the noticeably cooler temperatures expected on Monday, June 22, 2026. The Mauritius Meteorological Services has issued a high-swell warning, and as someone who lives here, I can say these conditions are taken very seriously on the island, especially for anyone thinking of venturing out to sea or spending time along the southern and western coasts.

What brings these large swells to Mauritius?
This weather pattern is caused by a strong anticyclone southwest of the Mascarenes, which is pushing moderate but cold trade winds across Mauritius. These winds don’t just mean lower temperatures; they also whip up the ocean, generating large swells of up to 4 meters. The roughest sea conditions will be found beyond the reefs, and that’s why the warning is particularly important for anyone planning boat trips, surfing, or fishing today.
How does this affect your holiday plans?
While June is usually an amazing time for beach weather in Mauritius, these occasional winter swells remind us the Indian Ocean is powerful and unpredictable. Personally, I’ve seen these storms change beach conditions fast, going from calm to unsafe in just a couple of hours. That’s why the current advice is clear: don’t swim, surf, or take a boat out from the west or south coasts today. Even a quick beach walk during high tide can be risky, as waves may overtop the coastal roads and paths.

The cool winds will also make it feel less humid than the island’s summer months. Expect maximum temperatures around 25 to 27 degrees Celsius along the coast (a very pleasant European springtime feeling), but if you’re heading inland to spots like Grand Bassin or Moka, pack a sweater, as it could dip to 14°C at night, chilly by Mauritian standards!
Practical safety advice for tourists
- Stay away from the sea and beaches: Especially in the west and south during high tide. Wait for the official all-clear before resuming water activities.
- Stick to inland attractions: Consider visiting nature parks, historic sites, or exploring vibrant towns such as Curepipe or Rose Hill instead of coastal activities today.
- Dress for cooler weather: Bring a light jacket or sweater, especially if touring in the highlands or after sundown.
- Check official updates: For the latest on sea conditions, visit the Mauritius Meteorological Services website before planning outdoor activities.
- Heed local advice: Hotel staff and tour operators are usually well-informed about closures and risks.
