January is the wettest month (218 mm, about 22 rainy days) and July the driest (51 mm). The sea is warmest in April at 29.8°C and coolest in July at 26.2°C.

Getting there

A direct flight from London Gatwick to Seychelles International Airport (SEZ, 10 km from Victoria) takes roughly 10 h 54 min - long-haul (7 h+) by UK standards. Time-zone: Indian/Mahe.

Records and extremes, 1991-2020

The hottest day recorded in Seychelles between 1991 and 2020 reached 30.5°C on 17 April 2016; the coldest fell to 23.0°C on 22 July 1996. In April one day in ten tops 29.1°C and about 1% of days pass 30°C; in July one night in ten drops to 24.0°C or below. The wettest single month of the period was November 2019 with 597 mm, against a November average of 144 mm.

January to April: fewer rain days in February, more sunshine in April

January is the wettest month, so it suits travellers who can keep outdoor plans flexible rather than depend on clear skies. February brings a useful improvement: rain days fall from 22 to 13, while daytime temperatures reach 28°C. That makes it a sensible choice if warmth matters but frequent rain would frustrate you. March has more rain days than February, though slightly more sunshine too. April is the hottest month and offers 6 hours of sunshine daily, with sea temperatures reaching 30°C. The catch is that April still averages 17 rain days. Pack light clothing and a rain layer, and leave room to shift swimming plans around the weather.

May to August: July is driest, but not sunniest

May stays warm, with days around 28°C and sea temperatures of 29°C, but its 18 rain days make it less appealing if avoiding rain is your priority. June eases towards cooler conditions, with fewer rain days and slightly cooler swimming water. July is the driest and coolest month, making it a good fit for travellers who prefer less heat. However, its 3 hours of daily sunshine are the lowest monthly average: drier does not mean consistently sunny. August keeps the same daytime and sea averages of 26°C, with a little more sunshine but more rain days. Evenings remain warm throughout this period, so breathable clothing is more useful than heavy layers.

September to December: brighter autumn days, then more frequent rain

September retains the cooler daytime average of 26°C, but rain days rise to 16 without an increase in sunshine over August. It is a weaker choice if you want either the driest weather or the brightest days. October and November offer a better sunshine balance, each averaging 6 hours daily, with days at 27°C and the sea at 28°C. Rain remains part of the picture, so these months suit flexible outdoor plans rather than a firm expectation of dry days. December stays warm but has 23 rain days, the highest monthly count. For a December trip, take light rain protection and avoid making every day's plans depend on sunshine.
