Hot days, warm nights and comfortable swimming

The heat is steady rather than extreme, but humidity of 81% can make it feel close, particularly when you are active. Pack loose, light clothing and leave room for shade and breaks around midday rather than planning to be outdoors constantly. Evenings offer little cooling, so breathable nightwear and accommodation with effective cooling are sensible priorities. The sea averages 29°C, making swimming a strong reason to choose October if warm water matters to you. That warmth does not guarantee suitable swimming conditions on any particular day, though: treat the sea temperature as a comfort guide, and check local conditions before getting in.

Plan for rain rather than uninterrupted sunshine

With about 23 rainy days, rain needs to be part of your plans rather than an occasional inconvenience you hope to avoid. That does not mean every wet day is a washout, but the figures cannot tell you when a dry spell will arrive. Sunshine averages about 4.3 hours within 11.7 hours of daylight, so daylight should not be confused with clear skies. Keep outdoor plans movable, carry rain protection that is comfortable in the heat, and have something in mind for wet periods. October makes more sense if you can enjoy warmth despite cloud and rain; it is harder to recommend if your holiday depends on spending most days in the sun.
