Over the last few years (this one excepted for obvious reasons) we have spent three winter months in Southern Spain.
Evenings are cool but most days are 18-22C - delightful for walking a bit, lunch in the square, or by the sea, etc. Approx 2 hours extra daylight compared to Somerset. Most days spent outside, not stuck in wondering whether it's going to rain, or when it's going to stop..
Inspector - they are beautiful snowy landscapes. But even dry but cold (UK usually damp and cold) it is still not for me. It takes all sorts!!
