August is the height of Mauritius’s cool dry season and the busiest tourism month of the year. European summer holidays bring the largest volume of visitors, particularly from France, the UK, and Germany. Rainfall averages just 30–50mm for the entire month and falls in brief isolated showers. Daily sunshine hours average 7–8 hours. The south-east trade winds blow steadily at 15–25 knots, providing a refreshing breeze along the coast.

The west coast (Flic en Flac, La Preneuse, Tamarin) and north coast (Grand Baie, Trou aux Biches) are sheltered from the trade winds and offer calmer, warmer swimming conditions than the east coast throughout August.

This combination of low humidity, low rainfall, and consistent sunshine makes mauritius weather august the most reliably pleasant period for land-based touring and hiking.

Standard beach clothing covers daytime activities. Include a long-sleeved rash guard for snorkelling in the cooler water. Walking shoes or trail trainers are useful if you plan to hike.

August diving conditions are excellent despite the cooler water temperatures (22–24°C). The reduced rainfall means outstanding visibility — up to 30 metres at sites like Flic en Flac, Coin de Mire (Gunner’s Quoin), and the famous wall dive at Trou aux Biches. For snorkellers, the calm lagoon at Mont Choisy remains glassy on most August days due to its sheltered north-facing aspect. Sea turtles are commonly spotted along the east coast reef systems.
