This cluster of islands in the south west corner of the southern Indian Ocean is the epitome of island paradise. It has a tropical climate so you should expect year-round high temperatures and a distinct rainy season and dry season. The mercury rarely drops below the mid-20s in the winter (June to August); in the Southern Hemisphere’s summer (December to February) you can expect the temperatures to rise to over 30 degrees Celsius. This warmer weather coincides with the wet season, but although showers might be heavy, they rarely stick around for too long. And if it’s raining one side of your chosen island, it could be clear on the other. Thanks to its position in the open ocean far from any large land masses, it’s very hard to predict the weather, especially in the long term, so you can’t take online forecasts as a given. Here’s our month-by-month guide to the Seychelles’ weather and climate.
January is the height of summer when the temperatures, humidity and rainfall are at their highest. Despite this, December and January in the Seychelles are a popular time to travel due the holiday season. If you’d rather avoid the rain, it might be worth considering a trip to the Maldives instead as it’s one of the country’s driest months.
The rainy season continues into February but there is less precipitation than in January or December. February marks the middle of the Hawksbill turtle hatchling season which usually runs from January to March. Seeing hundreds of tiny hatchlings make their way to the water from their nests is an amazing spectacle but some beaches may be off limits to give them the best chance to survive.
We recommend visiting the Seychelles in March, particularly later in the month, as the northwest monsoon ends. This means that there’s less rain but the temperatures will still be high. Any rain tends to come in short sharp bursts and clears quickly.
With hardly any breeze, the temperatures rise in April – it’s one of the hottest times of the year. April also the driest and therefore one of the best months to visit the Seychelles. If you like diving or snorkelling, head to the Seychelles in April to make the most of the perfect underwater visibility. The higher temperatures may mean that your time is best spent in the shade of a palm tree or taking a dip in the Indian Ocean rather than hiking through the pristine forests.
With the return of the winds, this time from the southeast, humidity drops in May but the temperatures in the Seychelles remain in the high 20s or low 30s. It’s another great month for snorkelling or diving with warm waters and great visibility. There are still rain showers but these tend to pass quickly.
The temperatures drop slightly throughout the Seychelles in June, but they’re still up there in the mid-20s. The wind picks up during the month and you’ll start to see surfers and windsurfers out on the water.
July is another dry month but again the winds will have increased. Beaches on the islands’ north and west coasts will be relatively sheltered from the wind. Due to summer school holidays and monsoon season in some of our other favourite destinations like the Maldives and Thailand, this is a very popular time to visit the Seychelles. You should book well in advance of your trip.
August is another popular month in the Seychelles because of the European school holidays. It is usually quite dry, however, one of the windiest times of the year and the conditions on the south and east coasts of the islands may not be suitable for swimming. There could also be more seaweed washed up on the sand at this time.
The winds die down in September, but there’ll still be a cooling breeze coming from the south east. The temperature in the Seychelles is an average high of 27 degrees. As September marks the end of the school summer holidays in Europe, this is a great time to get a good deal but make the most of the drier and calmer weather.
If you like snorkelling and diving, October is the best time to visit the Seychelles. The underwater visibility is at its best this month as there’s a window of time between the south east and north west trade winds.
The wind changes direction from the southeast to the northwest in November and rainfall amounts increase in November. The sea will still be relatively calm and the visibility for snorkelling and diving remains good.
The northwest trade winds that arrived in November bring the rain in December – there’s a reason why the islands are so lush and green. Although this is not the best time to visit weather-wise, it is a popular time of year to travel, particularly over the Christmas and New Year period.
