Seychelles Weather

Seychelles is all about warm air, balmy seas and a tropical climate that barely lets up all year. If you’re after sunshine and heat, you’re in for a treat: temperatures rarely dip below 28°C, and the sea sticks close to 28-30°C. The vibe here is humid and breezy, with rainfall peaking in the wetter months but never putting a proper damper on your holibobs.

Mahé, Praslin and La Digue are the big hitters, but each island has its quirks. Mahé, the largest, tends to catch a bit more rain, while the smaller islands can feel slightly drier. You’ll find consistent warmth wherever you land, with the odd shower rolling through to keep those palm trees looking lush.

Spring (March - May): Spring in Seychelles is warm, humid and lively. Air temperatures hover between 31°C and 32°C, with the sea reaching up to 30°C. Rain starts to ease off, dropping from 180mm in March and April to 150mm in May. Sunshine ramps up to 8 hours a day, so your beach days are looking top-tier.

Summer (June - August): Summer is a touch cooler, but still plenty warm for the UK crowd. Expect air temperatures around 28°C to 29°C, sea temperatures at 26°C to 27°C, and rainfall at its lowest - just 80mm to 100mm. Humidity sits at 77-78%. Days are sunny with 7-8 hours of sunshine, perfect for a dip or a lazy afternoon on the sand.

Autumn (September - November): Autumn keeps things steady with air temperatures from 29°C to 30°C and sea temperatures at 27°C to 28°C. Rain edges back up, hitting 120mm in September and peaking at 210mm in November, but sunshine holds at 7 hours a day. It’s still prime beach weather, just bring a brolly for those passing showers.

Winter (December - February): Winter is warm and humid, with air temperatures sticking around 30°C to 31°C and sea temperatures at 28°C. Rainfall is heavier, especially in January at 380mm, but sunshine stays at 5-6 hours a day. Even when the clouds roll in, it’s hardly chilly - think T-shirt weather with a side of tropical drama.

The best time for a beach holiday in Seychelles is late spring through summer - May to September. During these months, rainfall is at its lowest (just 80mm to 150mm), air temperatures sit comfortably between 28°C and 31°C, and the sea is always inviting at 26°C to 29°C. You’ll get up to 8 hours of sunshine a day, which means plenty of time for swimming, sunbathing or chasing those Insta-worthy sunsets.

If you want the island vibe but can’t wait for summer, April is a winner too, with warm sea and loads of sunshine. Mahé and Praslin both deliver during these months, so you’ll never feel short-changed on the beach front. Basically, the weather’s a whopper for jollies almost any time you book.
