What is the weather like in Seychelles in August and September?

August and September in Seychelles are defined by the **Southeast Trade Winds** (known locally as the *Vent des Alizés* or *Suet*). During these months, you can expect slightly cooler temperatures ranging from **24°C to 29°C**, lower humidity, and a consistent breeze that makes the tropical heat much more comfortable. While it is technically the "dry season," short tropical showers are still possible, but they rarely last long enough to ruin a day of exploring.

The most significant impact of this season is on the sea conditions and beach suitability. The trade winds blow strongly from the southeast, which can make the ocean quite choppy, particularly on the exposed southern and eastern coasts of the islands. If you are planning to travel between islands, be aware that the **Cat Cocos ferry** crossing from Mahé to Praslin (which typically costs **SCR 1,300-1,500** for a return economy ticket) can be a bit of a rollercoaster. For those prone to sea sickness, we recommend visiting a local pharmacy like **Behram’s** in Victoria to pick up Avomine or similar tablets for around **SCR 80**, or opting for a 15-minute internal flight with Air Seychelles instead.

**Choosing the right beaches is crucial during August and September:** * **Avoid the South and East:** Beaches like **Anse Royale** on Mahé or **Grand Anse** on Praslin often experience heavy surf and significant deposits of seaweed (seagrass) during this time. * **Seek out the North and West:** To find the calm, turquoise water Seychelles is famous for, head to the leeward side of the islands. **Beau Vallon** on Mahé, **Anse Lazio** and **Cote d'Or** on Praslin, and **Anse Severe** on La Digue remain sheltered and perfect for swimming and snorkeling. * **Safety First:** Be extremely cautious at **Grand Anse, Petite Anse, and Anse Cocos** on La Digue. While stunning, the "Suet" winds create dangerous undercurrents and rogue waves that can be life-threatening even for strong swimmers.

**Pro Tips for Visiting During This Season:** August and September are the absolute best months for hiking. The cooler air and lower humidity mean you won't overheat as quickly on the trails. The **Copolia Trail** in the Morne Seychellois National Park (entry fee **SCR 100** for non-residents) offers breathtaking 360-degree views of the Ste Anne Marine Park without the oppressive midday sun. Additionally, if you are a fan of windsurfing or kitesurfing, head to **Anse aux Pins** or **Anse Faure** on Mahé's east coast, where the conditions are world-class during this peak wind period.

By the second week of September, you may notice the winds beginning to fluctuate. This "transition period" can occasionally bring a bit more rain than August, but it also signals the start of calmer seas. If you are a diver, late September is a strategic time to visit as you might catch the beginning of the high-visibility season as the winds die down. Regardless of when you arrive, always pack a light rain jacket and a high-SPF reef-safe sunscreen, as the breeze often masks the true strength of the equatorial sun.
