Weather conditions during a vacation in Seychelles in September are quite similar to summer. The air temperature on the archipelago hovers around +29°C, and the Indian Ocean warms up to +26°C. Occasionally, there may be brief nighttime showers, but these have little impact on the overall weather.
September also marks the start of the fall diving season. During a Seychelles vacation in the fall, dive centers are bustling with activity. Experienced divers can rent equipment, while beginners have the opportunity to take lessons and embark on their first dive with an instructor.
