Expats may be surprised to find that Norway is not bitterly cold all year round. Despite its northerly location, the coastal climate in Norway is temperate, thanks to the warming effects of the Gulf Stream flowing along its coast. Summer occurs between late June and early August, and brings pleasantly mild days with temperatures reaching 22 °C (72°F), and sea temperatures of 64°F (18°C). 

In winter, much of Norway is snow-clad with extremely low temperatures in the north and the low-lying inland regions of the south. Temperatures drop well below zero. In contrast, the coast enjoys milder winters, although gales and rain are common. In spring, between May and mid-June, Norway is at its prettiest with everything coming to life and blossoming and melting snow swelling the waterfalls.
