Southern Europe in May

April through June delivers perfect weather without the crowds that turn narrow streets into human traffic jams. Rome in May means 22°C days and actual Italians still in the city. July and August? That's when locals flee to the coast and temperatures hit 35°C in inland cities. But September and October might be the sweet spot—warm sea temperatures, harvest season in wine regions, and hotel prices drop 40% from summer peaks. Here's what nobody mentions: shoulder season closures. Many Greek islands shut down restaurants and hotels from November through March. Portugal's weather stays mild year-round, but Atlantic beaches get rough winter swells. Spain's regional festivals matter more than seasons—Seville during Easter week costs triple normal rates, and Barcelona during Mobile World Congress in February sees hotel prices spike. Winter has its charms though. Rome's museums have no lines in January, and Christmas markets in southern France create cozy atmospheres. Just pack layers—Mediterranean winters are mild but damp, and many buildings lack central heating.
