Average temperatures in Barcelona

Average air temperatures above might appear a bit low for Barcelona and Spain if you look at the diagram below, but remember that average air temperatures are measured in the shade and out of the wind - they are not measured in direct sunlight. All official air temperatures on all weather forecasts are always measured in the shade. It will always feel hotter if you are standing in direct sunlight because what you are feeling is the air temperature and on top of that you are feeling the “heat” radiation caused by the direct light of the sun. So it will always feel and be hotter in the sunlight than in the shade. The same applies to a thermometer. It will give a higher reading in direct sunlight than in the shade.  Because the amount of sunlight can be very different depending on the time of day and the cloud cover, rain etc, the average air temperatures are always measured in the shade and also out of the wind, so that the thermometer only reads the temperature of the air around the thermometer.

Sunshine hours Barcelona

Sunshine is a big attraction of a visit to Barcelona. A sunny climate does make life here seem more agreeable than in northern European countries. But Barcelona is not hot all year round, Summers are long and hot and winters are much cooler, but with lots of sunshine. Barcelona gets 2500 hours of sunshine a year on average. That's an average of 7 hours a day. Rainfall varies and can cause low water levels in reservoirs at times, and lack of rain the the spring can cause increases in forest fires.

Average sunshine in Barcelona

With so many sunshine hours it is natural for Barcelona to be on the forefront of solar energy. Barcelona was one of the first cities in Europe to introduce special legislation concerning the use of solar energy. The Solar Ordinance law, which came into force in August 2000, applies to newly built, rehabilitated and fully renovated buildings. This law makes the use of solar energy compulsary for 60% of sanitary hot water supplies. This regulation applies to buildings intended for residential, health-care, sports, commercial and industrial use and, generally, any activity involving the existence of dining rooms, kitchens, laundries or other circumstances that lead to a large consumption of hot water

Snow in Barcelona

Barcelona can get a very light fall of snow about once a year but generally snow is a rare sight in Barcelona. There can be some frosty nights, especially up in the hills of Tibidabo and Collserola. See photos of Barcelona snowstorm in March 2010. For a cold snap there is a city plan of action called '"Operació Fred d’Emergència," to deal with icy road conditions in the hills. This plan has salt spreaders and even 5 snow ploughs on the alert for any significant snowfall. Salt bins can be distributed around the higher parts of the city in the districts of Les Corts, Gràcia, Sarrià-Sant Gervasi, Horta-Guinardó and Nou Barris, so that residents can salt pavements if need be. For the homeless, municipal shelters are made ready in case the temperature drops to freezing levels and emergency teams of city aid workers and Red Cross (Creu Roja) volunteers around the city keep a watch for homeless people and offer them a place in a shelter. If you are a skiing or snowboarding fan, then head for the Pyrenees mountains where there is an abundance of snow and ice at the many ski resorts near Barcelona in the Catalan/Spanish and French Pyrenees.
