Warm afternoons, cooler evenings and bracing swims

Pack light layers rather than treating October as an extension of summer. A T-shirt may feel comfortable on a warm afternoon, but a jumper and light jacket are sensible for evenings. The warmer days can reach 23.5°C or more, while the coldest nights can drop to 10°C or below, so packing only for the averages would leave you short. The sea averages 21°C, which is bracing rather than comfortably warm. Swimming is an option if you tolerate cooler water, but it should be a bonus rather than the main reason to travel. This month suits travellers who prefer walking in mild weather to spending the day in strong heat.

Rain is the main compromise

The catch is rain, not excessive heat. October is wet, so leave room to move outdoor plans around rather than committing every day in advance. A waterproof jacket and shoes that cope with wet ground will be more useful than extra summer clothes. There are about 5.7 hours of sunshine within 10.8 hours of daylight, leaving scope for pleasant time outside without promising clear skies throughout the day. Make use of dry spells and avoid leaving everything outdoors until late afternoon, when daylight is more limited. If your holiday depends on sitting outside every day, October is a less suitable choice than its mild temperatures might suggest.
