Generally speaking though, Seville is the hottest city in Spain. Temperatures start to climb in April and the sunshine lasts until well into September.

For those seeking year-round warmth in 2026, the Canary Islands remain the undisputed champion, often called the "Land of Eternal Spring." Islands like Tenerife and Gran Canaria boast average winter highs of 21°C (70°F) and over 3,000 hours of sunshine annually. On the Spanish mainland, the Costa del Sol in Andalusia—specifically cities like Malaga and Marbella—offers the mildest winters in Europe, with daytime temperatures often reaching 18°C (64°F) even in January. If you prefer extreme summer heat, the Andalusian Plain, including Seville and Córdoba, is the hottest region in Spain; summer temperatures here frequently exceed 40°C (104°F), though winters are short and very mild. Another high-value option is the Costa Tropical in Granada, where a unique microclimate allows for the growth of tropical fruits like mangoes and avocados. Generally, the further south you go toward the Mediterranean or the African coast, the more you can enjoy a life characterized by outdoor cafes and t-shirt weather throughout the year.
