Answer:
Northwest coast of Europe
Explanation:
The Northwest coast of Europe, that stretches from Northern France, to the Low Countries, to the west of the Scandinavian Peninsula (essentially Norway), including the British Isles (Britain, and Ireland), has remarkably cool summers, that are often rainy and windy. This is due to not only the northerly location of the region, but also because of the influence of the Atlantic Ocean, and its regional subdivisions like the Irish Sea, the North Sea, and the English Channel.
The ocean currents make winters less cold that in continental regions, and they also make summers cooler than in continental regions. In other worlds, ocean currents make climate milder as a whole, and that is why coastal regions have a less extreme climate than inland regions.
