Mild days, with layers needed after dark

The daytime average is comfortable for walking without the heat becoming the main consideration. Warmer days can reach 21.4°C or more, but that is a bonus rather than the temperature to build your packing around. Nights average 15.9°C, with the colder ones falling to 12.4°C or below, so bring a jumper and a jacket for evenings rather than relying on summer clothes. A light layer you can remove during a sunny afternoon is more useful than packing only for warmth or only for cold. November makes sense if you prefer being active in mild conditions; it is a less convincing choice if you want to spend most of your time lying in the sun.

Plan around rain, and treat swimming as optional

There is about 6.0 h of sunshine within 10.0 h of daylight, so November is not simply a grey-weather proposition. The catch is rain: keep outdoor plans movable and pack a waterproof jacket and shoes you are comfortable wearing in wet conditions. Sunshine is an average, not a promise for each day, so avoid making the whole trip depend on clear skies. Swimming is also a matter of tolerance rather than an obvious daily activity. The sea's year-to-year range is 20°C to 22°C, which puts it around the bracing end of holiday swimming. Pack swimwear if you enjoy cooler water, but have a dry layer ready for afterwards rather than expecting to stay warm in it.
