Traveller notes on Le Morne in August

Notes from nearby Port Louis (38 km away)

Le Morne doesn't have its own notes for August yet — these are about Port Louis, close enough to share the season.

August is winter here and the regulars' advice is about which side of the island you book. The south-easterly trades blow hard through July and August and do not ease until well into September; on the east and south coasts they can take the beach away from you altogether, which is why the boards point people to the north and west. Our row sits on the sheltered side at 24.9C by day over 20.5C nights, and even here the wind averages 28.6 kph. Rain looks frequent at 11.5 days but totals 38.3mm, three millimetres a time. The sea holds 24.8C. Their east-coast figure runs a degree or two under ours, which is the wind rather than the thermometer. The record: humidity 72 percent, 10.4 hours of sun and AQI 39.

Other months in Le Morne

Mauritius-forum regulars are clear that July is winter, and that the coast you pick decides the holiday: the wind on the east and south coasts is at its strongest then and makes them feel cooler, while the west coast is relatively sheltered from those south easterlies and feels warmer. Sea temperatures are a touch cool but fine once you are in, one resident describes winter days of 23C and up with low humidity and cooler high-teen evenings, and another notes that winter now starts later and finishes earlier than it used to. Le Morne's July record: 24.3C days, 20.4C nights, 28mm across 8.3 precipitation days, a 25C sea - and the strongest wind of its year at 31.8 kph.

Forum posters consistently recommend timing a Le Morne visit toward mid-to-late September rather than earlier in the month, since the peninsula's west-coast position gets less rain than the rest of the island this time of year but early September can still be quite windy. Posters describe September overall as late winter in Mauritius - warm, sunny, low-humidity conditions with generally little rainfall, more favorable toward the north and west of the island where Le Morne sits. Posters are direct that being a peninsula, Le Morne runs consistently windier than other parts of Mauritius regardless of exact date, with trade winds keeping the air noticeably cooler. Posters generally rate the second half of September as the more comfortable window for this specific spot.
