The best time to dive in the Seychelles is from April to May and October to November. However, the Seychelles is a good choice for year-round diving. Within the suggested months, you’ll find warm water temperatures averaging approximately 84°F (29°C) and exceptional visibility of up to 100 feet (30 meters). At this time, the surface conditions are at their calmest, allowing liveaboards to reach the most remote dive sites. On the other hand, July to August brings the southeast monsoon. With it comes strong winds and choppy surface conditions. The water temperatures drop to about 77°F (25°C). These variables are particularly welcoming to whale sharks who arrive in the Seychelles in search of plankton-rich waters. The air temperature remains fairly steady throughout the year. The thermometer generally reads between 75 and 90°F (24 and 32°C). And currents vary from dive site to dive site rather than by season.
