Thanks to the Gulf Stream, Scandinavia is warmer than you might expect. Oslo and most of Norway are considered to have a temperate climate, but it can fluctuate greatly from year to year in the northern regions.
Except for the climatic differences in the northern and southern regions, Norway’s climate also varies from coastal to inland areas. While the coastline tends to be more consistent with mild winters and cold summers, inland areas have the benefit of warmer summers, but considerably colder winters.
Oslo is more of the latter, but it still shares some characteristics of the coastal areas. The city is considered to have a humid continental climate, according to the Koppen Climate Classification System.
Oslo occupies the northern end of the impressive Oslo Fjord. In all other directions, Oslo is surrounded by forests, ridges, and lakes.

Primavera in oslo
Spring sees another rapid change in temperature, as the winter sun melts the snow again. Technically, spring is considered to be the driest time of the year, with only light rains, but the water is, in fact, abundant thanks to the melting snow banks. Early spring is still cold, so don’t get too excited just yet.
What to pack: You’ll still need your heavy coat in the spring, so don’t take the shirts out just yet. Also, waterproof shoes are a must: while spring is dry, the streets of Oslo can get quite wet thanks to melting snow.

Verano in oslo
Many travelers assume that Oslo is a city of eternal winter, but Oslo is as much a city of summer and sun as can be expected in this part of the world. During the summer months, hikers and fresh air enthusiasts head to the parks and countryside to make the most of the weather. Summer weather is typically mild and pleasant, with a series of hot spells. In fact, you can expect a fair amount of good weather. July and August are the warmest months, with temperatures in the 60s, but temperatures have been known to rise above 80 degrees Fahrenheit (27 degrees Celsius), although this occurs very rarely.) As the fjord is mainly covered by land, the water temperature can get quite high for this part of the world.
The rainy season peaks in August when the rains fall most heavily.
What to pack: Summer is nice, and jeans and T-shirts are generally appropriate in all temperatures. However, don’t forget to bring a light jacket or sweater for cold summer nights.

Winter in oslo
In winter, Oslo transforms into the winter wonderland for which it is known. Snow is abundant, making the city the ideal place to practice winter sports. Temperatures average a chilly zero degrees Fahrenheit from late November through March, with January being the coldest month of the year and a temperature of -2 degrees Fahrenheit. Extreme cold is rare, but temperatures of -25 degrees Fahrenheit (minus 18 degrees Celsius) have been recorded from time to time. Ice develops in the inner parts of the Oslo Fjord, and during exceptionally cold winters, the entire fjord can freeze over.
Things can be a bit miserable in winter, but with a little initiative, there are plenty of winter activities for you to enjoy within the city limits. The weather can be unpredictable due to the Atlantic winds, so it is best to be prepared for all eventualities, regardless of the season.
What to pack: In the winter, pack lots of warm layers and a waterproof windbreaker or snow jacket, especially if you plan on doing outdoor activities. Boots, mittens, a hat, and a scarf are also a must.

Polar lights and the midnight sun in Oslo
An interesting phenomenon in Norway is the seasonal change in the length of day and night. Daylight lasts for only about six hours in southern Norway for much of winter, while darkness prevails in the north. These dark days and nights are called Polar Nights. In contrast, in midsummer, there is very little darkness during June and July, and you will experience very long days.
