Weather and best times to visit these historic Unesco sites in Spain
Spain’s UNESCO sites are spread across different climates, so the best time to visit can vary depending on the region. Generally, spring (April to June) and fall (September to early November) are ideal for most of the country. During these months, temperatures are mild, crowds are smaller, and outdoor exploring is more comfortable. In southern cities like Granada, Córdoba, and Seville, summers can be extremely hot, so early spring and late fall are best. Barcelona and the north coast, including Santiago de Compostela and Burgos, are pleasant in summer, though expect more tourists. For central Spain, such as Toledo, Salamanca, and Ávila, late spring or early autumn offer sunny days without the intense summer heat. Garajonay National Park in the Canary Islands has a subtropical climate and is enjoyable year-round, though winter is especially popular with those looking to escape colder weather elsewhere. Overall, shoulder seasons are your best bet for balancing good weather and fewer crowds across Spain’s historic and cultural gems.
