Sitting just below the equator in the southern hemisphere, Seychelles enjoys a hot and humid climate throughout the year. Peak season is May to November, during the Seychelles winter. However, most visitors prefer the months April, May, October and November. During this period, the climate is pleasant and relatively dry, and there are fewer tourists competing for the sunbeds. Local thermometers barely shift from winter to summer. Annual average temperatures are about 27°C (81°F), with temperatures changing just two or three degrees in either direction.
While peak season is perfectly timed for vacations from the northern hemisphere, winter escapees must contend with significant rainfall from October to April. The wettest month is January, with an average monthly precipitation of 379 mm (14.9 in.) Rainfall is heaviest on mountainous islands, like Mahé. Unsurprisingly, humidity is high, especially during the summer. And while the main islands are rarely affected, cyclone season arrives every December to March. The combination of monsoon rains, hotter days and heightened humidity makes the Seychelles summer marginally less appealing for visitors. Yet December and January still draw significant tourist numbers as people flee gloomy northern winters.
Swimming in glassy waters lapping idyllic beaches is the main attraction. Access to the waters can be affected by high and low tides and the seasons. In fact, several tiny islands become mere specks of sand during high tide. Some are predicted to be permanently submerged by rising sea levels. However, the rolling tides have less impact on the inhabited islands, and waters are always accessible from popular beaches. Use a reliable guide for current information.
