What This Means for Tourists
September is one of the most comfortable months in Mauritius. Temperatures remain mild, and although today’s forecast includes some clouds and occasional showers, mostly over the east and the high central plateau, the weather still supports plenty of outdoor fun. Coastal areas are generally warmer and drier, perfect for lounging at Flic en Flac or Trou aux Biches. Central spots like Curepipe or Vacoas will be cooler and could feel crisp, especially if a rain shower passes through. If you’re planning a day out, keep a light waterproof jacket in your bag for those quick showers, especially inland.
Coasts vs Plateau: Temperature Differences
The central plateau, covering towns like Vacoas and Curepipe, sits about 600m above sea level. Today, you’ll see it’s about 21 to 24°C during the day there, sometimes you’ll need a light sweater if the wind picks up or clouds linger. Down by the coast, the story changes, beaches and seaside towns stay between 26 and 29°C, ideal for a swim, sunbathing, or just sipping a fresh coconut. Nights cool down more in the interior too, so coastal hotels feel warmer at night.

Rain, Clouds, and What to Pack
Most showers today are expected in the east and center this morning, with localized cloud bursts in western Mauritius in the afternoon. “Occasional” means nothing heavy or endless, usually quick, easily waited out under a cafe awning or beach shelter. If you plan to hike up Le Pouce or walk around Port Louis, check the forecast before heading out and maybe start earlier in the day. The wind is light, from the east, and usually won’t interfere with beach plans or boat tours, though swells offshore are about 2 metres, so scheduled sea excursions should be confirmed in advance. Want to safely explore the sea or book an island tour? I always recommend checking options on mauritiusevents.com, they update their tours based on daily weather.
Sea Conditions and Tidal Info
The sea is moderate outside the lagoon, with swells around 2 metres from the southwest. This means swimming is safest within the lagoon, and only strong swimmers or those with a guide should head beyond the reefs today. If in doubt, ask your hotel team or a licensed tour operator before hiring a kayak or paddleboard. Tides might matter if you plan to surf, snorkel, or sail; high tides arrive at 11:41 and 23:01, with low tides at 05:06 and 17:41. Water visibility after a quick rain is still fine in most places, though out in the bay it might be a bit cloudy right after showers.
September evenings feel mild along the beach, and I like bringing a light jumper when dining outdoors. The sun still feels strong around midday, so sunscreen isn’t optional. Sunrise is at 5:59 and sunset at 18:05, the days are getting a little longer as we look toward Mauritian spring.
