Seychelles weather by month
Climate source: Meteorological data for the Seychelles is based on weather statistics gathered for the period 1991 to 2020 by the Seychelles National Meteorological Services from the closest weather station: Seychelles International Airport (SEZ), located around 10km (6mi) south of the capital, Victoria, on Mahé Island.
Advice on the best time to visit the Seychelles is based on average local weather statistics, when the weather conditions are generally better than at other times of the year. We consider high and low temperatures, risk of rain (and thunderstorms, etc.), amount of sunshine and sea temperature. For general outdoor activities we favour clear, rainless days with a temperature range between 18°C (64°F) and 27°C (80°F); and for hot-weather activities we favour clear, rainless days with a temperature range between 24°C (75°F) and 32°C (89°F). Often, the best times to visit correspond to high season and therefore involve higher prices.
