Wanderlust World Wanderlust World Norway holds the title for the highest average annual rainfall in Europe. Its western coastal regions receive over 200 inches (5,000 mm) of precipitation per year.
This extraordinary rainfall is driven by the North Atlantic Ocean's moisture-laden winds, which are forced upward by the coastal mountain ranges. As the air rises, it cools and releases persistent precipitation, creating a temperate rainforest climate along the fjords and coast.
