About Denis Island Lodge

January is the wettest month of the year in the Seychelles: temperatures are warm, humidity levels high, and short, tropical downpours are common. Cyclone activity elsewhere in the Indian Ocean often results in heavy cloud cover too.

Although generally calm, the warm, north-west trade winds tend to litter Praslin’s east coast with seaweed – perfectly harmless, but can make swimming less pleasant.
Picture-perfect beaches are abound on opposites sides of the island. Waves and currents are also strong on Mahé’s north-west coast at this time.

For wildlife spectacles, January has definite highlights and Bird Island is particularly special at this time of year. The Hawksbill turtle hatchlings start emerging from mid December to mid March, and their journey to the ocean is wonderful to witness. Throughout the year the bird-watching is excellent, but from end-August to end-May, migratory birds from Alaska and Siberia appear.

April is the calmest, warmest month of the year, making it one of the best months to visit the Seychelles. The wind drops, the temperature is delightfully warm and the seas are calm, offering great diving and brilliant visibility.
The birding is great, particularly on Bird Island, when migratory birds from Alaska and Siberia are resident and displaying their often spectacular breeding plumage in their final month ashore. An enormous, chattering colony of Sooty Terns roost on the island from March-November.

In late April, the capital city, Victoria, comes alive for the colourful parades of the Carnaval International de Victoria, with street performances, costume parades and parties.

May is the start of a relatively dry period and one of the best months to visit. There is little rain with plenty of warm beach days under clear blue skies.

The cooler, drier, south-east trade winds bring lively seas to south-west Mahé and result in seaweed being washed up onto the beaches of Praslin’s south coast, though idyllic beaches await elsewhere.

Birding is good, particularly on Bird Island, with migratory birds from Alaska and Siberia appearing up until the end of the month, displaying their often spectacular breeding plumage in their final month ashore. A vast colony of Sooty Terns chatter and roost from March-November.

June marks the change of seasons but there’s little rain at this time and lovely long, hot, clear days. Coming before the start of the European Summer holiday season, June is often a quieter time to visit, and in some cases reduced rates can also be found.

The cooler, drier, south-east trade winds bring lively seas to south-west Mahé and result in seaweed being washed up onto the beaches of Praslin’s south coast, though pristine beaches await elsewhere.

For wildlife enthusiasts, Green Turtles, an endangered and protected species, are more commonly seen at this time (June and September), often whilst laying their eggs on the beaches of Bird Island. Birding is also particularly good here, with breeding birds and a vast colony of Sooty Terns chattering and roosting from March-November.

July is a time to bask in lovely warm days, with little chance of rain.

October is warm with calm conditions and rain increasing towards the end of the month.

During this calm season (October and November), whales migrate past the islands and you may spot Southern Right, Humpback and Short-finned Pilot whales. The Hawksbill Turtle nesting season also begins in October, with Bird Island being a great place to witness the event. It is unusual for a guest who stays 3-4 nights not to see a Hawksbill turtle laying their eggs. Migratory birds from Alaska and Siberia are also present here, alongside a vast, noisy colony of Sooty Terns.

The warm, north-west trade winds bring good underwater visibility for diving but do also tend to litter Praslin’s east coast with seaweed, and can make for waves and strong currents on Mahé’s north-west coast. Picture-postcard beaches abound in other areas.

For some island culture, the Festival Kreol takes places on Mahé, Praslin and La Digue in late October, with colourful celebrations of Creole heritage.

The Seychelles Ocean Festival, celebrating marine diversity and highlighting reef protection, is held annually at this time.

Whales migrate past the islands throughout November and you may spot Southern Right, Humpback and Short-finned Pilot whales.
