What’s September Weather in Seychelles Like?
Seychelles in September offers one of the best combinations of pleasant temperatures, dry conditions, and affordable travel costs you’ll find all year. Sitting just below the equator, the islands enjoy a tropical climate with minimal seasonal change — but September falls during the drier southeast trade wind season, making it ideal for outdoor adventures.
Metric | September | Annual Average |
| Temperature (°C) | 27 | 28 |
| Rainfall (mm) | 154 | 225 |
| Sunshine Hours per Day | 12 | 12 |
| Sea Temperature (°C) | 27 | 28 |
September’s southeast trade winds bring a warm, pleasant breeze — perfect for cooling down under the tropical sun.
Why September is a Great Month to Visit Seychelles
Perfect Balance of Warmth & Sunshine
Expect average daily highs of 27°C with lows rarely dipping below 26°C. With 12 hours of daylight and relatively low rainfall, it’s a month made for beach days, hikes, and water sports.
One of the Driest Months
September sees about 154 mm of rainfall, often in short, refreshing showers. They’re usually over quickly, leaving the skies bright again.
Budget-Friendly Travel
It’s considered a shoulder season — meaning lower accommodation rates and better deals on tours, while still enjoying fantastic weather.
Ideal for Outdoor Adventures
From swimming and snorkelling in calm coves to birdwatching in lush nature reserves, September gives you the perfect playground.
Things to Keep in Mind
Winds & Surf: Around Mahé’s Anse Intendance, southeast trade winds can make waters turbulent — better for surfers than swimmers.
Seaweed on Praslin: Between May and October, you may spot seaweed on the East Coast. Head to the northwest beaches for clearer waters.
Humidity: Being equatorial, humidity is always present — pack light, breathable clothing.
