Warm enough for light clothes, not dependable heat

The average daytime high of 20.2°C should suit travellers who prefer being outdoors without strong heat. A T-shirt may be enough in sunshine, but keep a light jumper handy for shade and evenings. Warmer spells do happen: the warmest 10% of days reach 23.2°C or more. Properly hot beach weather is much less likely, with only 2% of days reaching 25°C, so midday is better treated as a chance to enjoy the warmth than something to avoid automatically. Nights average 18.4°C, although the coldest 10% fall to 14.8°C or lower. Pack long trousers and a warmer layer rather than assuming every evening will be comfortable in shorts.

Allow for rain and a bracing sea

October offers about 6 hours of sunshine within 10.9 hours of daylight, leaving useful time outdoors without promising clear skies throughout. With about 8 rainy days, a light waterproof and plans you can rearrange are sensible. The figures do not tell you when rain will fall, so avoid building the whole holiday around uninterrupted beach days. Sea temperature averages 21.4°C, below the 22°C threshold for comfortable swimming. That makes a dip more appealing if you tolerate cool water; if you prefer a warm sea, swimming may not be the main draw. The year-to-year sea range of 20°C to 23°C also means the feel of the water can vary noticeably between visits.
