When planning a trip to Barcelona, it is important to choose the right wardrobe to feel comfortable in any weather. In summer, from June to August, it is usually hot and sunny here, so the basis of your luggage should consist of light, breathable items made from natural fabrics: t-shirts, shorts, sundresses, and, of course, swimwear for a beach holiday. Do not forget sunscreen with a high SPF, a hat, and sunglasses. Evenings can be a bit fresher, especially by the sea, so a light cardigan or shawl will come in handy. Given that maximum temperatures can reach nearly 29°C, give preference to light-coloured clothing.

Winter in Barcelona (December-February) is mild, with average temperatures around 8-10°C, but evenings can be cool, down to 4-5°C. You will need sweaters, jeans or thick trousers, as well as a mid-season jacket or a light coat. A scarf and gloves will also not go amiss. Spring (March-May) and autumn (September-November) are transitional seasons with changeable weather. During the day it can be warm, up to 15-21°C, while towards the evening the temperature drops. At this time, the layering principle is perfect: t-shirts, long-sleeve tops, cardigans, and a light jacket, possibly a windbreaker, as it can be windy on the coast. September and October can be rainy, so a compact umbrella or a light raincoat will be very useful. Regardless of the season, comfortable footwear for long walks around the city is an absolute necessity, as Barcelona is best explored on foot.
