If you visit Mauritius in December or January, you get the tropical heat—lush, humid, and intense. But from June to August, the climate shifts. The temperatures settle between 20°C to 26°C (68°F to 79°F).
It is the kind of weather that doesn't require air conditioning. You can hike without melting, sleep under a light sheet, and spend all day in the sun without the oppressive heat of the tropics. The skies are often a piercing blue, broken only by the dramatic, fast-moving clouds that roll over the central plateau.
The humpback whales migrate to Mauritius during the austral winter (June to September). However, the resident sperm whales and spinner dolphins are actually easier to spot in the summer due to the calm sea conditions around the south coast. Operators in Tamarin Bay report that the flat mornings of December to March offer the most reliable sightings.
Summer in Mauritius means average daytime highs of 28–33°C (82–91°F) , with humidity often exceeding 80%. The west and north coasts (e.g., Grand Baie, Flic-en-Flac) are typically drier and sunnier, while the east and central plateau receive more rainfall.
The wildcard? Cyclone season (January to March). While direct hits are rare (roughly once every 3-5 years), the island frequently experiences heavy squalls and rough seas. The upside: these storms pass quickly, leaving behind spectacularly clear skies and dramatic surf.
This is the crown jewel of the Mauritian summer. Between November and March, the waters off the coast of Mauritius sometimes glow electric blue at night. This is caused by phytoplankton (dinoflagellates) that emit light when disturbed.
Where to see it: Le Morne or Poste Lafayette (conditions vary nightly). Why summer? The warmer water and specific nutrient flows trigger this bloom. You can swim at night and watch every kick create a galaxy of blue stars around your body. You cannot see this in July.
