Spain
Barcelona runs on a city-plus-beach dual mode that no other European capital matches — by 11am you might be in the Gothic Quarter under stone, by 4pm you are at Barceloneta in the sand, by 9pm you are at a rooftop in the Eixample. The local style adapts: linen pieces that move from city to beach without changing, sandals that walk cobblestones and sand, a swimsuit always under whatever else. The Mediterranean breeze keeps evenings 5-7°C / 41-45°F cooler than midday, so a cardigan or shirt in the bag is non-negotiable for restaurants. La Rambla pickpocketing is real — crossbody bags only, never backpacks worn behind you.
