Average temperature across Mauritius in December.
Grand Baie, Trou aux Biches, Cap Malheureux
Late-summer energy peaks in December with balmy, humid days and frequent tropical downpours; beach parties and holiday crowds are in full swing along the north shore. Small-boat schedules are more changeable and hotels fill for the festive season; keep an ear on weather forecasts for any cyclone watches. Bring breathable clothing, a rainproof layer, and expect lively harbours and busy beach restaurants.
Flic en Flac, Tamarin, Le Morne
December brings hot, humid conditions with more frequent tropical showers and increasing storm watch concerns; Le Morne and the west coast are busy with holiday visitors. Boat tours to nearby reefs and dolphin spots run but will be postponed if seas roughen, so book arrangements with flexible terms. Bring insect repellent for evenings and prepare for lively beachfront scenes and higher prices during the festive month.
Belle Mare, Palmar, Île aux Cerfs
Warm, humid conditions dominate December with frequent showers and occasional storm watches; Île aux Cerfs and beach resorts are at their liveliest for holiday-makers. Ferry and water-sport operations remain busy but will be postponed when squalls pass through, so plan quick alternatives for rainy periods. Pack breathable clothes, a lightweight rain jacket, and prepare for crowded beaches and vibrant seaside restaurants.
Le Morne, Gris Gris, Souillac
Strong summer humidity dominates December with frequent showers and the occasional tropical system; the south coast sees vibrant holiday activity and many hotels book early. Le Morne is lively with kiteboarders when winds suit, though water excursions are often paused during heavy rain. Bring insect repellent for dusk and be ready for festive crowds and higher seasonal prices along the shoreline.
Curepipe, Moka, Black River Gorges
December in the central plateau is warm, humid and frequently cloud-covered; summery showers are common and thunder can form over the ridges in the afternoon. The mountains are lush but path conditions can be variable, so guided walks are recommended for safety. Pack breathable clothing, a waterproof shell, and be prepared for localised flooding on small tracks after heavy storms.
Port Mathurin and outer reefs
December is hot, humid and prone to heavy downpours or tropical disturbances; Rodrigues is lively with holiday visitors but services now begin to feel the pressure of peak season. Boat and diving operators remain active but will adjust itineraries around storms; book flexible tickets and allow time for weather-related plans to shift. Pack breathable clothing, a sturdy rain jacket and contingency time if flights are involved.
There are no major festivals or events in Mauritius during December to be aware of.
