What Is the Temperature in Mauritius in June?
In June, daytime temperatures in Mauritius typically sit between 22°C and 26°C on the coast, dropping to around 16°C to 19°C at night. The island is in its dry, cooler season, which runs from roughly May through September. Humidity is lower than in summer, trade winds blow steadily from the south-east, and rainfall is minimal on most of the island. For visitors from the northern hemisphere arriving mid-winter, the climate feels mild and pleasant rather than hot.
The figures above apply to coastal areas such as Grand Baie, Flic en Flac and Blue Bay. The central plateau, including Curepipe and Rose Hill, sits several hundred metres higher and runs about 3°C to 5°C cooler. If you are staying in the highlands or planning a hike up to the Black River Gorges viewpoints, pack an extra layer.
Average Highs, Lows and Daily Conditions
Daytime Temperatures
Along the coast, June highs average around 24°C to 26°C. The warmest part of the day is typically between noon and 3 pm, but the south-east trade wind keeps things comfortable rather than stifling. You can sit in direct sun without discomfort, which is not always true in January or February when the island is in its humid, cyclone-season summer.
The west coast, sheltered by the Moka and Black River mountain ranges from the prevailing trade winds, tends to be slightly warmer and drier than the east. Flic en Flac and La Preneuse on the west coast are good choices in June if you want the most reliable sunshine and the warmest beach days.
Night-time Temperatures
Nights in June are noticeably cool by Mauritian standards. Coastal lows sit around 17°C to 19°C, while the plateau can dip to 13°C or 14°C. Most villas and hotels do not have central heating, and air conditioning units are not designed to warm a room. A light fleece or a long-sleeved layer for evenings is genuinely useful, especially if you are dining outdoors or watching the sunset from a terrace.
Humidity and Comfort
Relative humidity in June averages around 70 to 75 percent, compared with 80 to 85 percent in the summer months. The practical difference is significant: you can walk around Port Louis or cycle along the coastal path without arriving drenched. The trade wind does most of the work, making even a warm afternoon feel airy.
Rainfall in June: How Wet Is It?
June is one of the driest months on the Mauritian calendar. The island as a whole receives an average of around 40 to 60 mm of rain in June, but the distribution is uneven. The east coast and the central plateau, which face the trade winds directly, catch more rain than the west and north-west. On the west coast, monthly rainfall in June can be as low as 20 to 30 mm.
Rain in June tends to arrive as short, sharp showers rather than sustained downpours. A shower might last 20 minutes in the morning and then clear completely. If you are island-hopping to Rodrigues or taking a catamaran trip to the northern islands, you may not see rain at all during a one-week stay. That said, the central plateau can be misty and grey for stretches of a day, particularly around Curepipe and Vacoas.
The practical upshot: June is not a month where you need to plan around the weather the way you might in February. A waterproof jacket tucked into a day bag is enough preparation.
Sea Temperature in Mauritius in June
The Indian Ocean around Mauritius cools gradually through the dry season. In June, sea surface temperatures average around 24°C to 25°C. That is warm enough for comfortable swimming and snorkelling without a wetsuit, though some visitors who find 27°C or 28°C ideal will notice the difference from the summer months.
Visibility underwater in June is generally excellent. Lower rainfall means less sediment runoff into the lagoons, and the calmer conditions on the west and north coasts allow the water to settle. The Blue Bay Marine Park in the south-east and the snorkelling reefs around Trou aux Biches in the north are at their clearest in the dry season.
For surfers, June marks the beginning of the south swell season. Tamarin Bay on the west coast and One Eye (Le Morne) pick up consistent swells from the Southern Ocean. One Eye in particular becomes a serious wave during the dry season and draws experienced surfers from around the world. Beginners are better off on the sheltered north-coast lagoons.
Sunshine Hours in June
Mauritius receives an average of around 7 to 8 hours of sunshine per day in June on the west and north coasts. The east coast gets slightly fewer, partly because the trade winds bring more cloud cover from that direction. Overall, June is one of the sunnier months of the year, which is counterintuitive to visitors who assume the tropics are always sunnier in summer. The wet season brings heavy cloud cover and afternoon storms; June does not.
Sunrise is around 6:15 am and sunset around 5:45 pm in June, giving you roughly 11.5 hours of daylight. The evenings feel short compared with a European summer, so early dinners and sunsets from the beach at 5:30 pm become part of the rhythm.
Regional Differences Around the Island
North Coast (Grand Baie, Trou aux Biches, Cap Malheureux)
The north is sheltered from the full force of the south-east trade wind by the island's topography. In June it offers calm lagoons, reliable sunshine and water that is clear enough for snorkelling without a guide. Grand Baie's beach can get busy on weekends, but the smaller coves around Cap Malheureux and Pointe aux Canonniers are quieter. The north is a strong choice for families in June.
West Coast (Flic en Flac, La Preneuse, Le Morne)
The west coast is the warmest and driest part of the island in June. Flic en Flac has a long, open beach and a reef that creates a wide, shallow lagoon. Le Morne at the south-western tip has a dramatic backdrop and the best kitesurfing and surfing conditions on the island. The sunsets here are worth arranging your schedule around.
East Coast (Belle Mare, Palmar, Trou d'Eau Douce)
The east faces the trade wind directly, which keeps things breezy and slightly cooler. The beaches are wide and beautiful, but the wind can make lounging on the beach less comfortable for some visitors. Kitesurfers and windsurfers, on the other hand, find the east coast conditions excellent in June. Rain showers are slightly more frequent here than on the west.
South Coast (Blue Bay, Souillac, Gris Gris)
The south coast is rockier and more exposed. Blue Bay has the island's most protected marine park and is excellent for snorkelling in June. The Gris Gris cliffs near Souillac are dramatic in any season, and the south generally sees fewer tourists than the north or west, which suits visitors who prefer a quieter pace.
Central Plateau (Curepipe, Quatre Bornes, Rose Hill)
The plateau is cooler and cloudier than the coast in June. Temperatures here can feel quite brisk by local standards, and locals wear jackets and scarves without irony. If you are spending time in the central towns for practical reasons (shopping at the Quatre Bornes market, visiting the Mahebourg waterfront market) bring a layer.
What to Pack for Mauritius in June
Packing for June in Mauritius is straightforward once you accept that it is not a hot-weather-only destination at this time of year.
Clothing:
- Light cotton or linen clothing for daytime, including shorts and t-shirts for the beach and casual outfits for towns
- One or two long-sleeved layers for evenings, a light fleece or cardigan works well
- A waterproof or packable rain jacket for day trips or hiking
- If you are visiting the central plateau regularly, a warmer mid-layer is genuinely useful
- Smart-casual outfits for restaurant dinners, many beachside restaurants have a relaxed dress code but nicer establishments expect more than swimwear
Sun and Sea:
- Sunscreen with a high SPF: the UV index in June is still high (typically 7 to 9 on clear days) despite the cooler air temperature
- Reef-safe sunscreen is strongly encouraged, particularly if you are snorkelling in protected marine areas
- Snorkelling mask and fins if you have them, rental equipment is available but quality varies
- Rash vest or UV shirt for long days on the water
Footwear:
- Sandals for the beach and casual wear
- Comfortable walking shoes for markets, towns and light trails
- If you are hiking in Black River Gorges, trail shoes with grip are worth bringing
Other Essentials:
- Mosquito repellent: June is low season for mosquitoes compared with summer, but repellent is still useful for evenings near vegetation or freshwater
- A reusable water bottle: tap water in Mauritius is treated and generally safe to drink in most areas, but bottled water is widely available if you prefer it
Is June a Good Time to Visit Mauritius?
June is one of the most consistent months to visit Mauritius. The combination of dry conditions, moderate temperatures, calm seas on the west and north coasts, and lower humidity makes it comfortable for almost any type of trip, whether that is beach relaxation, water sports, hiking or exploring the island's towns and markets.
It is also shoulder season in terms of crowds. The European summer rush picks up in July and August, so June tends to be quieter and, in many cases, slightly cheaper for accommodation than peak season. The island does not empty out the way some beach destinations do in their off-season; restaurants and attractions are fully open, and boat trips and excursions run on normal schedules.
The main trade-off is that the sea is cooler than in December or January, and evenings require a layer. For anyone who finds high heat and humidity uncomfortable, those are not trade-offs at all.
Practical Tips for June in Mauritius
Book sunset activities in advance. Catamaran trips, sunset cruises and dolphin-watching excursions on the west coast are popular year-round. In June, they are not as booked out as in August, but the best operators fill up a week or two ahead.
Plan hikes for the morning. The Black River Gorges National Park and the Chamarel area are at their best in the morning before any cloud builds over the plateau. Starting a hike by 7 am means you are back at lower altitude before any afternoon mist arrives.
Check which beach suits your plans. If you want flat, calm water for children or non-swimmers, the north and west lagoons are the right choice. If you want surf or wind, the south-west and east coasts deliver in June.
Carry cash for markets. The Flacq market (held on Wednesdays and Sundays) and the Port Louis Central Market accept cash only for most vendors. ATMs are widely available across the island.
Respect the reef. The dry season's clear water makes the temptation to stand on coral or touch marine life greater. Blue Bay Marine Park and other protected areas have rules against this, and reef-safe sunscreen is a minimum courtesy wherever you swim.
