Bilbao Climate and Weather

The climate of Bilbao is oceanic, rather humid and often rainy, but without extremes of temperature. Bilbao doesn't enjoy the hot, dry and well-defined summer common to Spain, and the city has quite fluid seasons. The average temperatures in summer, between June and August, range between 55°F (13°C) and 78°F (26°C), making the city unusually cool by Spanish standards. The winters are similarly mild, with temperatures between December and February averaging between 40°F (4°C) and 56°F (13°C). The average annual rainfall is high, but is spread fairly evenly throughout the year, with the most rain being experienced during spring and autumn. November and April are usually the rainiest months. Light snow is possible in winter, but sleet is far more common. Summer is the most popular time to visit Bilbao, partly because it is by far the most popular time to visit Spain in general. During the warm summers the beaches around the city are at their best. The most festive month of the year is August, when fireworks and parades are common as the city celebrates Semana Grande, giving tourists another reason to travel to Bilbao in summer.
