Nights average 25.5°C; one night in ten drops to 24.8°C or lower, so pack a layer for evenings.

It is a reasonable choice: hot days but expect showers. The best months for Seychelles on our scoring are July, February, April; months averaging 25°C or more: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec.

Warm days, with little relief at night

The heat is fairly steady rather than extreme, with an average daytime high of 26.8°C. That is 12.2°C warmer than London in October, so light summer clothing makes more sense than an autumn wardrobe. The catch is 81% humidity, which can make even these temperatures feel sticky, particularly when you are walking around. Nights average 25.5°C, barely cooler than the daytime high, so do not count on evenings to freshen up. Breathable fabrics and accommodation with cooling are sensible priorities. This suits travellers who enjoy consistent warmth; it is less appealing if you need cool nights to sleep comfortably.

Plan for rain, not a washout

With about 16 rainy days, October is a wet choice, and a rigid schedule of outdoor activities could become frustrating. That does not mean you should write off the month: average sunshine is about 5.5 hours a day, leaving scope for time outside. Still, that is well short of the 12.1 hours of daylight, so expect a mix rather than clear skies throughout. Pack a lightweight waterproof and something to protect your belongings when rain arrives. Leave room to change plans instead of assigning every outdoor activity to a fixed day. October works best if you can accept wet spells as part of the holiday.

Warm water is the strongest reason to go

The sea averages 27.8°C, making swimming a strong reason to choose October. Its year-to-year range of 27°C to 28°C also suggests that water temperature is unlikely to be the uncomfortable part of a swim. If your main aim is warm water and relaxed time outdoors whenever the weather allows, the month makes sense. If your priority is maximum sunshine or avoiding rain, it is a less convincing fit. July, February and April rate better overall, so consider those if your dates are flexible. For October itself, go for the warmth and sea, with realistic expectations about cloud, humidity and rain.
