Does it rain a lot in Seychelles in 2026?

Seychelles Meteorological Authority month guides put the wetter load under the northwest monsoon, peaking around December and January. Showers can arrive day or night, with a clear preference for late morning and afternoon bursts, sometimes with thunderstorms. Even in peak months you can still see several dry, sunny days in a row. December averages still leave room for dry days mixed into wetter weeks.

March and April taper the rainy season. April is the monsoon reversal: lighter winds, calmer seas, and occasional afternoon tropical showers rather than the January pattern. From about May through September the southeast trades dominate. Rain becomes lighter and shorter; July is often among the driest weeks of the year. Pre-dawn showers can still appear, but afternoons often stay workable for beach and café plans: Social life in Seychelles.

October and November close the drier half-year and reopen warmer rains as winds weaken and swing. Plan umbrellas for monsoon months, not a full wet-season wardrobe for every week of the calendar.

Long-run climate summaries place mean annual rainfall on Mahé near about 2,880 mm at sea level, with mountain slopes climbing higher still toward Morne Seychellois. That is a genuine wet-island total, not a desert mirage. Coastal Victoria and Beau Vallon still get plenty of monsoon rain, but a hillside lease can feel damper and greener than a west-coast beachfront flat: Living in Victoria.

Praslin and La Digue follow the same inner granitic pattern: wetter northwest-monsoon months, drier southeast-trade months, without Mahé’s tallest orographic boost. Outer coral islands farther south often run much drier on long-run averages. Most movers still choose Mahé first for services, then filter island and hillside for rain comfort: Where to live in Seychelles.

Because catchment supplies much of the fresh water, short drought spells inside the drier half-year can still stress tanks and Public Utilities Corporation (PUC) water planning even when annual Mahé totals look high. Ask landlords about roof leaks, drainage, and mould on monsoon-facing walls before you sign.

A wet December week raises laundry time, mould risk in poorly ventilated flats, and sticky nights that push air conditioning. That lands on PUC electricity more than on umbrella spend: How expensive is Seychelles and Monthly budget for Seychelles. Humidity stays high even when showers pause: How humid is Seychelles.

Market fish and Creole takeaways still work through monsoon months; imported supermarket carts do not get cheaper because January rained: Groceries and eating out in Seychelles.
