The Seychelles is made up of over 100 idyllic islands and is best known as a warm, tropical honeymoon destination off the coast of East Africa. The archipelago consists of mountain rainforests, beautiful beaches, nature reserves, and coral reefs. There is never a bad time to visit Seychelles weather-wise as temperatures tend to hover around 86 degrees Fahrenheit year-round.

However, there is a mixture of tropical rainfall, sunshine, and sea breezes that make for a humid climate. Due to its location in the middle of the Indian Ocean only several degrees south of the Equator, the weather in the Seychelles can be unpredictable so take heed as you can go from rain showers to bright, sunny skies within short periods of time.

Seasonal Seaweed

From May through the start of October the South-East trade winds bring loads of seaweed to the popular island of Praslin. While it is a good thing for the local environment, it can negatively affect the usually pristine beaches for tourists. In order to avoid the seaweed buildup during this time, it is recommended to visit beaches on the other side of the island as they are typically free of seaweed.
