The climate along Norway’s coast is surprisingly temperate due to the warm currents of the Gulf Stream. The interior of the country experiences strong winds and severe frosts. If you take a Norway tour in the summer, however, you can see temperatures as high as 86°F with long hours of sunshine. The west coast experiences year-round precipitation and mild winter conditions. During the summer, the area around Oslo is the driest and warmest part of the country. The northern part of the country inside the Arctic Circle has continuous daylight at midsummer, and twilight all day during winter.
