Weather & seasons

Mauritius is in the Southern Hemisphere, so seasons run opposite to the Maldives: May–November is the cooler, drier winter (SE trade winds, about 20–26°C, one of the main tourist peaks) and December–April is the hot, humid summer (about 28–33°C, the warmest water, with January–March the peak cyclone risk). The north and west coasts are sheltered and calm; the east and south face the wind, with stronger breezes and swell in winter. Peak prices (Christmas/New Year, the July–August European holidays) do not always match the best weather. Season boundaries shift a little each year; below is the general pattern.

Southern-hemisphere seasons: summer (November–April) is hot at about 28–31°C by day, while winter (June–September) is mild at about 24–26°C by day and 17–19°C at night, so bring a light layer for evenings. The lagoon is about 27–28°C in summer and 23–25°C in winter.

November–April is the hot, humid summer, with the most rain in January–March; this is also the cyclone season, with the greatest risk from about January to March. May–October is the drier, cooler winter, with steady southeast trade winds: the east and south coasts are windier and rougher, while the west and north are calmer, and Le Morne is a well-known kite spot from about June to September. April–May and October–November are the transition months, usually the best balance of weather and prices. Rain is heavier in the east, south and central highlands than on the west coast. Peak-price months (July–August, October, Christmas/New Year) do not fully overlap with the most comfortable weather; figures are editorial estimates from public climate data.

Month 1Wet season

Hot, wet and the peak of cyclone risk — only for flexible travellers chasing low prices.

Weather
High summer: hot, humid and showery, with the most concentrated rain of the year. This is also the core of the cyclone season, so a tropical storm can disrupt plans.
Sea
Warm water (about 28°C), but rain and swell can stir up the lagoon and cut visibility; the west and north are usually calmer than the east and south.
Crowds & price
Just after the Christmas/New Year peak, prices ease; low-season deals start to appear.
Good for
Spa, pool and beach time between showers; choose flexible bookings and travel insurance that covers weather disruption.

Month 2Wet season

Cheap but wet, with real cyclone risk — a bet on the weather.

Weather
Still the hottest and most humid stretch, with frequent heavy showers; cyclone risk stays high, especially in February.
Sea
Warm water but often choppy or murky after rain; west-coast lagoons are the most sheltered.
Crowds & price
One of the quietest, cheapest months, with a short bump around Lunar New Year.
Good for
Choose a resort with plenty to do indoors and keep a spare day for the weather.

Month 3Wet season

The tail of the wet season: getting better, prices still low, some weather risk left.

Weather
Late summer: still hot and humid, with rain and cyclone risk starting to ease towards month-end.
Sea
Warm water; conditions improve as the month goes on, but visibility is still patchy.
Crowds & price
Prices are still low, with a small bump around Easter in some years.
Good for
Beach, lagoon and short excursions get easier to schedule late in the month; keep a weather buffer.

Month 4Shoulder

Settled weather, warm water and moderate prices — one of the best-value windows.

Weather
A transition month: humidity and rain fall away and the weather settles, with cyclone risk now low.
Sea
Warm water (about 27°C), calm lagoons and good visibility — a very good time for the water.
Crowds & price
A short Easter-holiday bump, then prices fall back — good value.
Good for
Snorkelling, catamaran trips and island excursions all work; good light for photos.

Month 5Shoulder

Comfortable, dry-ish and moderately priced — widely seen as one of the best months.

Weather
Autumn: drier and clearly less humid, with comfortable days and cooler nights.
Sea
Calm and clear early on; the southeast trades start to build, so the east and south coasts get breezier.
Crowds & price
Prices are moderate, before the July–August peak.

Month 6Dry season

Cool, dry and comfortable — good for touring, and the start of the kite season at Le Morne.

Weather
The coolest month (still around 25°C by day), dry, with steady trade winds; bring a light layer for evenings.
Sea
Cooler water and steady southeast winds: the east and south get swell, while the west and north lagoons stay comfortable; Le Morne is at its windiest.
Crowds & price
European summer holidays push prices and crowds up, so book early.
Good for
Touring, hiking, kitesurfing at Le Morne, and dolphin trips on the west coast; a few winter days are too cool for long swims.

Month 8Dry season

Comfortable weather at peak-season prices — choose your coast for the wind.

Weather
Still cool and dry with plenty of sun and steady winds.
Sea
Trade winds remain strong; the west and north coasts are the calmest, and the kite season is in full swing at Le Morne.
