Andalucia consistently ranks as the hottest place in Spain in October. It's warm enough to rent a villa with private pool and you'll find rates are considerably lower than in summer – just make sure there's a terrace where you can sit outside and barbecue dinner.

The warmest part of Spain in October is undoubtedly the Canary Islands, particularly the southern coasts of Tenerife, Gran Canaria, and Fuerteventura. While mainland Europe begins to cool down, the Canaries maintain a "subtropical" climate with average highs ranging from 24∘C to 27∘C (75∘F to 81∘F). If you prefer to stay on the mainland, the Andalusia region—specifically cities like Seville, Málaga, and Almería—remains the warmest, with daytime temperatures often reaching the mid-20s. The "Costa del Sol" stays pleasant enough for sunbathing well into the month, and the sea temperatures are still warm from the summer heat. In contrast, northern Spain and the Balearic Islands (like Mallorca) start to see more frequent rain and cooler evenings in October, making the southern Mediterranean coast and the Atlantic islands the gold standard for late-season sun seekers in 2026.
