Is it hot in summer in Oslo?

Oslo is close to the North Sea and the Atlantic Ocean. Affected by the prevailing westerly winds and coastal warm currents, Oslo forms a temperate maritime climate. The climate is relatively mild and there is heavy rainfall throughout the year. Because Oslo is surrounded by mountains, jungles and wilderness on three sides, it has the beautiful scenery of a seaside city and the majestic momentum of relying on the mountains and dense forests. Most of the buildings on both sides of the streets are only six or seven floors, with strong medieval colors and uniqueness. Unique Nordic scenery. The contrast between Cangshan Mountain and green plains is very charming. 75% of Oslo's urban area is forest and cultivated land, and the per capita green area ranks first among European capitals. The city is located close to the bay, the air is humid, and the climate is warm and suitable.
