Spain can be enjoyable any time of year. The ideal months to visit are May, June and September (plus April and October in the south). At these times you can rely on good-to-excellent weather, yet avoid the extreme heat - and the main crush of Spanish and foreign tourists - of July and August. But there’s decent weather in some parts of Spain virtually year round. Winter along the southern and southeastern Mediterranean coasts is mild, while in the height of summer you can retreat to the northwest, to beaches or high mountains anywhere to escape excessive heat. The best festivals are mostly concentrated between Semana Santa (the week leading up to Easter Sunday) and September to October.
