Perfect sea and weather conditions for the Yacht Charter Seychelles. The archipelago, which is under the influence of strong winds, is dominated by a distinctive system consisting of two monsoons separated by a month of variable weather : the inter-season. From May to October, almost constant winds blow south easterly with clear skies. The winds drop in November and give way to north-westerly. The most humid & wettest months are from December to March. The south-easterly wind pattern returns in April. In between these two periods of south-easterly and north-westerly winds there are two short periods of calm or light winds. April and May are the sunniest months with a daily average of 7h50' to 8h20' of sun. These slight climate changes barely affect the temperature, which remains at an average of 28° to 32°C, both air and sea. No hurricane season in the Seychelles, winds rarely exceed speeds of 30 knots.
