Spring
A common shoulder season across much of the mainland, with lower demand on accommodation than summer and daytime temperatures generally comfortable for walking around cities.
Spain does not have one climate; it has several, running side by side. This guide explains the main patterns by region, defines the terms used to describe timing, and sets out a way to match your travel dates to what you actually want from the trip.
The Atlantic north (Galicia, Asturias, Cantabria, the Basque Country) has a temperate, wetter climate, with rain spread more evenly through the year than elsewhere in the country. The interior, including Madrid, sits on the meseta — a high inland plateau — and runs a continental pattern: hot summers, cold winters, and a wide swing between day and night temperatures. The Mediterranean coast, from Catalonia down through Valencia and Murcia, runs hot, dry summers with milder, wetter winters. The far south-east is drier still, among the driest parts of mainland Europe. The Canary Islands, being subtropical and Atlantic, run a different pattern again, staying markedly milder in winter than the mainland.
A shoulder season is the period between a region's busiest and quietest times, usually in spring and autumn. It tends to combine milder weather with fewer crowds at major sights, though exact timing varies by region and shifts with the local school calendar and festival dates rather than following a single date across the whole country.

The interior and the south run hottest during this period, which is worth weighing if your plans involve being outdoors during the middle of the day. The northern coast stays milder and greener.
A second shoulder season, often paired with harvest activity in wine-producing regions such as Rioja and Ribera del Duero.
The interior and the north can be genuinely cold, while the Canary Islands are a common winter alternative because their subtropical climate stays milder through this period.
Spain's midday rest period, often called a siesta in casual use, historically shaped opening hours in smaller towns more than in large cities; some shops and offices away from major tourist centres still close for part of the afternoon, which is worth checking locally rather than assuming either way.
