The weather is one of the many things that makes the Seychelles such a special destination, all year round.
With an average temperature of 27°C, and a range that rarely drops below 24°C or rises above 32°C it is rarely too hot and almost always perfect beach weather.
Of course, like anywhere in the tropics it does rain, but showers tend to be brief, lasting just a couple of hours, and are often localised to one island or even just one area of an island.
During the year the driest months are between May and September, with the wettest weather in November, December and January - but even during these months there will be plenty of sunshine before and after the showers.
Seychelles does have two main seasons that are determined by the trade winds.
From May to September the south east trade winds bring drier weather and steady winds, which can affect where you might want to stay. On Mahe some beaches on the south west of the island such as Intendance, Takamaka and Baie Lazare can be too rough for swimming, while the north and east coasts are fine. There can also be an increase in levels of seaweed in the water and on the beaches on the south west coasts - this is particularly a problem on Praslin where it could influence your decision to stay on Grand Anse.
The seas also makes for rougher boat crossings between the islands, so if you are prone to sea sickness you may wish to fly at these times.
From October to April the winds come from the north west. Breezes are more gentle, and most beaches are safe to swim on and largely weed free. On the flipside there is a greater volume of rain during this periods, particularly between November and January.

When is the best time to visit the Seychelles?
Given the Seychelles' year round good weather, the shortest answer is 'as soon you can'! With wondeful weather all year round, glorious warm temperatures and beautiful blue skies, there's no bad time to be here. However depending on what you want from your trip there are a few things you might want to consider:
Rain: Although it rains all year round in the Seychelles, there is on average more rain between November and January. That said, as with anywhere in the tropics rain showers tend to be short, lasting just a few hours rather than days at a time, so this needn't be a great factor in your decision. If you are particularly worried, then the months of June, July and August are the driest by far.
Heat: Most people will find that with cool sea breezes, swimming pools and beautiful seas the heat is never really an issue in the Seychelles. Night temperatures never top 25C all year round, making sleeping easy, and all but the most basic accommodation will offer air conditioning. If you are particularly sensitive to hear you might wish to avoid the hottest months of March, April and May and opt for a cooler, breezier time such as July to October.
Beaches and swimming: The majority of beaches in the Seychelles are fantastic all year round, looking stunning and offering great swimming. That said, if you have your heart set on staying at a property on the south west of Mahe or Praslin, you may wish to stay during the months of October - April, when the waves on Mahe's gorgeous south western beaches will be calmer making swimming safer, and there will be far less seaweed on Praslin's south / southwest coast.
Surfing and windsurfing are best during the southeast trade winds from May to September when winds and waves combine to offer a much more exciting experience.
Honeymoons are fantastic at any time - but if you feel small children may spoil the mood somewhat, you might wish to avoid visiting during the school holidays in Europe, which cause peak periods in July and August as well as December and around Easter.
Sailing is great all year round, though the stronger winds between May and October may offer more exciting conditions for some, while those looking for a peaceful cruise from beach to beach might prefer conditions between October and April. The Seychelles Sailing Cup is held in January, the Beau Vallon Regatta in October and the International Fishing Competition in November.
Snorkelling and scuba diving is great all year round, and dive operators will know which are the best sites for visibility at any one time of year. That said, the best all round underwater conditions can be found during April-May and October-November, when visibility can top 30 metres and the water temperature can be as high as 29C.
Bird Watching is best between the months of April to October. April is the breeding season for birds in the Seychelles, May to September is the nesting season for the terns and October is the main migration period.
