Hauts-de-France is northern France's dynamic region, forged from the historic provinces of Nord-Pas-de-Calais and Picardy. It is a land of soaring Gothic cathedrals, poignant WWI memorials, vibrant Flemish culture, and a rugged coastline along the Côte d'Opale. Lille, the cosmopolitan capital, anchors a region of surprising contrasts — from the underground citadels of Arras to the vast sandy beaches of Dunkirk and Boulogne-sur-Mer.
Hauts-de-France has an oceanic climate influenced by the English Channel and North Sea. Summers are mild and pleasant (17–22°C / 63–72°F) with long daylight hours. Winters are cold and grey (2–7°C / 36–45°F) with frequent rain. The region is one of the rainiest in France — plan for rain year-round, especially in autumn and winter. The Côte d'Opale experiences strong Atlantic winds, which make it ideal for kite surfing and sand yachting.
