Mauritius in December: festivities, weather and tips

Mauritius in December: Christmas magic in the tropics

December is the most singular month of the year in Mauritius. The island attempts a seemingly impossible synthesis between tropical summer — with its heat, humidity and first rains — and the fairy-tale atmosphere of the end-of-year holidays. Christmas trees in palm-fringed hotels, champagne on the beach to the sound of the waves, and fireworks over turquoise lagoons on New Year’s Eve: Mauritius in December is an experience like nowhere else in the tropical world.

It’s also the most expensive month of the year. Understanding this trade-off — exceptional atmosphere versus high prices and crowds — is essential to deciding whether December suits you. Our guide to the best time to visit Mauritius objectively compares every month according to your profile.

Weather and temperatures in December

Tropical heat settles in

December confirms the return of summer. Maximum temperatures settle between 28 and 32°C along the coasts, with peaks of 33°C on the hottest days at the end of the month. Nights are warm: 23 to 25°C on the coast. Air conditioning is no longer optional for most travelers — check that your accommodation has it before booking.

Humidity climbs progressively to 78-83% by the end of the month. The heat index can feel higher than the actual temperature, especially in poorly ventilated areas. The west coast — Flic-en-Flac, Tamarin, Le Morne — stays more comfortable than inland areas thanks to steady sea breezes.

Rainfall: the tropical rhythm sets in

The rainy season really takes hold in December. Rainfall increases to 100-130 mm on the northwest coast, over 10 to 12 days. The classic tropical pattern establishes itself: mornings generally sunny, clouds building up by late morning, brief but sometimes intense showers in the early afternoon, then often a return of clear skies in the evening.

This pattern is generally favorable for tourist activities: mornings are almost always usable for the beach and excursions, and rainy afternoons offer a welcome break or a chance to explore covered shops and restaurants. A light raincoat or compact poncho is still worth having with you.

Weather by coast in December

The climate difference between the coasts is even more pronounced in December than in November. The west coast — Flic-en-Flac, Tamarin, Le Morne — enjoys the driest, sunniest microclimate on the island thanks to the foehn effect of the central mountains. This is a considerable advantage during the onset of the rainy season.

The north coast around Grand Baie is intermediate but lively — ideal for those who want the festive atmosphere while still enjoying acceptable weather.

The east coast (Belle Mare) gets more rain in December and can have rainy afternoons. It remains pleasant early in the month before the rainy season truly settles in.

Warm sea and active marine life

The sea warms up quickly in December: 26 to 28°C. The lagoons are delightful for long swims. Underwater visibility is still acceptable early in the month (22 to 28 m) before dropping slightly toward the end of the month as plankton increases with the warmer waters.

It’s turtle nesting season: large females start approaching the white sand beaches to lay their eggs. At night, from mid-December through January, nestings can be observed from a distance and with discretion on certain isolated beaches in the south of the island. A rare and moving natural spectacle for the lucky few who witness it.

Cyclone risk: not to be overlooked

December is the third month of cyclone season. The risk is real but statistically moderate: one or two disturbances can affect the island in December, but direct, intense cyclones are less frequent than in January-February. The probability of a category 2+ alert during a 10-day stay in December is around 5-10%.

Our complete guide to cyclones in Mauritius explains the alert system and what to do. Taking out suitable travel insurance remains essential for any stay from December to April.

Crowds and prices in December

The busiest month of the year

December is, along with January, the most touristic month on the island. Christmas school holidays (generally starting December 20-22) trigger a massive influx of European tourists. Hotels are booked solid across all categories months in advance. Restaurants offer special festive menus, often at higher prices.

The atmosphere is extraordinary, but you have to accept the crowds, packed beaches and overwhelmed staff. In the main tourist areas (Grand Baie, Trou aux Biches, Flic-en-Flac), December feels like one big ongoing party — an experience in itself for those who enjoy the buzz of the holidays.

Peak prices: prepare your budget

Christmas and New Year prices in Mauritius are among the highest of any tropical destination in the Indian Ocean. Luxury hotels apply “event” rates with 5-7 night minimum stays, mandatory all-inclusive packages for the holidays, and prices that can triple compared to low season.

For New Year’s Eve, some 5-star hotels offer packages including the gala dinner, entertainment and champagne, which can exceed 500 to 1,000 euros per person. These packages are booked months in advance. Our Mauritius budget guide provides detailed benchmarks for each accommodation category.

If your budget is tight, the first week of December (before school holidays) is an interesting alternative: same weather, same tropical atmosphere, but still moderate rates — prices often double around December 20-22. Check our complete Mauritius accommodation guide to find the best options for your budget.

Things to do in December

The irresistible tropical Christmas atmosphere

The unique experience of December in Mauritius is simply living Christmas and New Year in a tropical setting. Grand hotels put up spectacular decorations: trees adorned with shells and peacock feathers, beach-attired Santas, tables set under the palms for lagoon-side Christmas Eve dinners.

On the evening of December 24, most hotels host Christmas parties with lavish buffets, sega shows and live music. In Mauritian villages, celebrations by the Catholic community bring moving midnight masses in small colonial churches — an authentic and touching cultural experience for travelers who take part respectfully.

Beach and water activities

The warm December sea (26-28°C) is ideal for long swims and water activities. The lagoons of the northwest coast are busy with boats and festive activities. Catamaran trips to the northern islets are beautiful in December, with the warm sea and often clear morning skies.

To find a little calm away from the high-season buzz, head away from the main tourist areas. The south coast (between Souillac and Bel Ombre) or the southeast coast around Mahebourg offer beaches that are less crowded even in December. Blue Bay and its protected lagoon are accessible and less busy than the northern beaches.

Swimming with dolphins and sea excursions

The spinner dolphins of Tamarin bay are present every morning, year-round. In December, sea conditions are good on the west coast. Our guide to swimming with dolphins details reliable, responsible operators. Book the swimming with dolphins in Tamarin excursion as soon as you arrive, as spots fill up fast in high season.

Ile aux Cerfs on the east coast is very popular in December. The catamaran excursion to Ile aux Cerfs with lunch on board should be booked several days ahead. The island’s turquoise lagoon and white sand beaches are spectacular even with the crowds. Ile aux Benitiers on the west coast is a less crowded and equally beautiful alternative.

Diving and snorkeling

Diving and snorkeling in December are pleasant despite slightly lower visibility than the winter months. The warm sea allows for long sessions without a thick wetsuit. Tropical marine life is in full swing. The wrecks around the island — the Stella Maru off Flic-en-Flac, the Sirius off Port Louis — are very popular and accessible.

Family activities

December is, above all, the month of family holidays with school-age children. Mauritius offers everything for an exceptional Christmas break: warm sea, varied activities, festive atmosphere. Our guide to family activities in Mauritius lists the best options for traveling with children during the holidays. Our family itinerary for Mauritius can be adapted for the two-week Christmas break.

For couples, the romantic atmosphere of the holidays is particularly successful in Mauritius. Our guide to couples’ activities suggests ideas for unforgettable moments — a Christmas dinner with your feet in the sand, a private catamaran outing for New Year’s Eve, or a stay at a luxury resort overlooking the lagoon.

Cultural discovery and gastronomy

The Christmas markets of Port Louis and the main towns are colorful and festive. Port-Louis’s central market in December blends holiday decorations, local Mauritian produce and early-season mangoes in an extraordinary atmosphere.

Visiting Chamarel and its Seven Coloured Earths in December is particularly interesting: the first heavy rains bring out the most vivid colors in the ferruginous earth, and the Chamarel waterfall reaches full flow — a remarkable visual spectacle.

Events in December

Christmas (December 25): national public holiday. A family, festive atmosphere across the island. North coast beaches host Mauritian family picnics to the sound of sega — a beautiful Creole tradition to witness. A day that’s both festive and popular, with unique local conviviality.

New Year’s Eve: the event of the year in Mauritius. Grand hotels host spectacular gala parties. The beaches of Grand Baie, Flic-en-Flac and the north coast are the stage for fireworks over the sea at midnight. For travelers who haven’t booked a hotel package, local celebrations in coastal villages offer an authentic, popular alternative.

Late Diwali: if the Hindu festival of lights didn’t happen in October-November, it can fall in early December. Diyas twinkle in the streets and temples — a mesmerizing sight.

Creole Christmas markets: in the shopping centers of Curepipe and Port-Louis, Christmas decorations sit alongside stalls of Mauritian handicrafts, ebony wood jewelry and local spices. A unique cultural blend that perfectly symbolizes Mauritius’s mixed heritage.

Recommended areas in December

West coast (Flic-en-Flac, Tamarin, Le Morne): the best choice for December. The island’s driest microclimate, calm sea, and a festive atmosphere without the excess of Grand Baie. December sunsets on the west coast are absolutely stunning — the clouds of the incoming wet season create extraordinary skies at the end of the day.

Grand Baie and the north coast (Grand Baie, Trou aux Biches): for those who want to be at the heart of the festive action. Grand Baie is the nerve center of Mauritian celebrations, with lively restaurants, night markets and daily boat trips. The atmosphere here is highly festive and international.

Pointe d’Esny and the southeast coast (Mahebourg, Blue Bay): to escape the crowds. This less touristy area offers almost deserted beaches even in December, more affordable accommodation and intact Mauritian authenticity. Blue Bay’s lagoon is one of the island’s finest for snorkeling.

Belle Mare and the east coast: for those who prefer the east coast, December is still pleasant with gentle trade winds. The white sand beaches are less crowded than on the north coast, especially on weekdays. The excursion to Ile aux Cerfs from Trou d’Eau Douce is spectacular in December with warm, turquoise waters.

Tips for planning a December trip

Book very early: for Christmas and New Year, the best rooms sell out 4 to 8 months ahead. Don’t delay your booking if you have fixed dates.

Travel insurance is essential: with cyclone season underway, insurance covering cancellations and emergency evacuations is a must. Check the specific cyclone clauses.

Air conditioning is essential: make sure your accommodation has air conditioning in every room. In December, sleeping without AC can be tough, especially on the hottest nights at the end of the month.

Transport: if you’re planning excursions, renting a car offers valuable flexibility. Our car rental guide for Mauritius covers the practical rules. In December, taxis are in high demand — agree on prices in advance.

Bring cash: small festive markets, roadside restaurants and street vendors only accept Mauritian rupees in cash. Bring enough for market purchases and tips.

Head out early for excursions: in high season, popular excursions — whale watching, dolphins, Ile aux Cerfs, catamaran trips — leave early in the morning. Book as soon as you arrive for the first available days and make the most of the mornings before the afternoon showers.

Comparison with neighboring months

If you’re torn between December and the surrounding months:

November is cheaper, less crowded and weather-wise very similar. If you can do without the Christmas-New Year atmosphere, November offers excellent value for money.

January carries on the festive New Year atmosphere with similar weather, but prices stay high in the first half of the month before gradually dropping.

For the best conditions without the crowds or prices of December, October and May remain the top choices.

Real budget for a December trip

The budget for December depends heavily on the exact dates. Before December 20, rates stay close to November levels. Between December 20 and early January, they can double or triple depending on the accommodation category, with minimum-stay requirements at many hotels. For a couple looking for a middle ground, the first week of December offers the tropical atmosphere and early holiday decorations without New Year’s Eve prices. Our Mauritius budget guide details price ranges by category and area, and our Mauritius accommodation guide helps compare villas, hotels and guest houses.

Verdict: should you visit Mauritius in December?

December is a month of extremes: the highest prices of the year for one of the most memorable experiences. If you dream of spending Christmas with your feet in the white sand of a turquoise lagoon, or watching New Year’s fireworks from a catamaran off Mauritius, December is the month to choose. The atmosphere is truly magical, like nowhere else.

On the other hand, if your priority is value for money, tranquility or the best weather conditions of the year, choose October, May or September. These months offer an equally beautiful island, calmer and much cheaper.

December remains generally pleasant weather-wise, especially early in the month before the intense heat of January-February sets in — provided you book very early, accept high-season prices and choose the west coast for its favorable microclimate.

Overall rating for December: 7.5/10 — Magical for the unique festive atmosphere, less good for value for money. The ideal month for those who can’t or won’t miss Christmas and New Year in the tropics.
