This huge country is largely characterized by freezing winters: latitude and continentality, as well as the position of the mountain ranges, contribute to make it one of the coldest countries on Earth.
The distribution of the population (the largest cities are located along the southern part of the country) and its scarcity (although Canada is one of the world's largest countries, it has approximately 35 million inhabitants), show how hard the environmental conditions are in much of the country, mainly because of the cold climate.
Nevertheless, during the short summer there may be some hot days, especially in the southern inland areas.

The only area where in winter the average temperature exceeds the freezing point (32 degrees Fahrenheit or zero degrees Celsius) is the coast of British Columbia (see Vancouver), where the climate is oceanic, cool and rainy.

The Rocky Mountains generally block the flow of mild Pacific air masses, while there are no topographic barriers that could block cold air masses coming from the North Pole, so that, apart from the west coast, the rest of the country experiences freezing winters.

The Atlantic coast (see Nova Scotia, Newfoundland) is much colder than the Pacific one, both because the prevailing winds are the westerlies (which therefore in the former case come from inland), and because along the Atlantic coast a cold sea current flows, the Labrador Current.

So, the temperature of the ocean near Halifax is 1 °C (34 °F) from January to April, while on the coast near Vancouver, it does not drop below 8 °C (46 °F) in February.

Arctic and subarctic climate

The vast Arctic and subarctic regions, from the northern islands to the Hudson Bay, experience only two seasons: a long winter, with night temperatures normally around -30/-35 °C (-31/-22 °F), and three months of summer, during which the temperature is around freezing or just above: in the Arctic areas the temperature hovers around freezing or rises a few degrees above, while in subarctic areas it rises above, but it remains on average below 10 °C (50 °F).


Here are the average temperatures of Alert, in the far north (in the Nunavut Province, at a latitude of 82 ° N, near Greenland), where only 155 millimetres (6 inches) of rain or snow per year fall.

In the northwest region, in the provinces of Yukon and Northwest Territories, the climate is strongly continental, with a long, cold winter and an intense summer, during which the daytime temperature can sometimes reach 30 °C (86 °F). Summer nights, however, remain cool. Of course, this applies to valleys and hilly areas: the high mountains remain obviously cold even in summer.
During winter, in this northwestern region the lowest temperature in North America has been recorded: on February 3, 1947, in Snag, almost 600 metres (2,000 feet) above sea level, on the border with Alaska, the temperature dropped to -63 °C (-81.5 °F). Cold waves like this are due to the proximity to Siberia: when a high pressure system moves over the Pacific Ocean, a "train" of cold air (which in North America is called "Siberian Express") flows from eastern Siberia, and sometimes reaches the mid-west regions of the United States as well. However, in Snag the average temperature of January is -27.5 °C (-17.5 °F), that of July is 13.5 °C (56.5 °F), with an average maximum of 20 °C (68 °F).

Rocky Mountains

In the Rocky Mountains of British Columbia and Alberta, the climate varies according to altitude and slope exposure.

The western slopes have a very humid and relatively mild climate, with precipitation exceeding 2,000 millimetres (80 inches) per year. On the contrary, in inland areas and on the eastern slopes, precipitation decreases rapidly, and drops below 500 mm (20 in) per year, in addition, the climate becomes continental, with very cold winters: in Calgary, at 1,000 metres (3,300 feet) above sea level, the average temperature in January is -7 °C (19.5 °F), while in Edmonton, more to the north and at 670 metres (2,200 feet), it's -10.5 °C (13.5 °F). Summers are mild, with cool nights, while days are pleasant, though there may some hot days, in which the temperature can rise to around 30 °C (86 °F).
During the cold months, in valleys and slopes facing east, the terrible Blizzard often blows from the north, but sometimes a totally different wind, the warm and dry Chinook, which is similar to the Föhn of the Alps but more intense, can raise the temperature in a spectacular way (by tens of degrees Celsius), so that snow can quickly evaporate (or better, sublimate). The Chinook causes such spectacular changes in temperatures, because of the considerable heating due to compression (the wind descends from very high mountains) but also to the different origin of the air mass (which is much milder because it comes from the Pacific Ocean). While the Chinook blows at the foot of the mountains, the Blizzard is a wind typical of the vast prairies and plains of Canada (see below).

Canada landscape

Great plains

In the Midwest plains, from the southern part of the Northwest Territories (see Fort Smith) to the central and southern plains of Saskatchewan and Manitoba (see Winnipeg, Regina), the climate is strongly continental, with long and cold winters and short summers, when days are warm and nights remain cool, but during which there may also be hot days.
The continentality is so strong that in the same place, the temperature can drop below -40 °C (-40 °F) in winter, and reach as high as 40 °C (104 °F) in summer.
Precipitation, which has a maximum in summer, is not abundant: west of Winnipeg it's lower than 500 mm (20 in) per year, and sometimes this region may experience periods of drought.
In winter, the blizzard brings terrifying snow storms.


In Regina, located at the 50th parallel, the average temperature is -16 °C (3 °F) in January, and 19 °C (66 °F) in July.

Pacific coast

On the Pacific coast, the climate is oceanic, with relatively mild but rainy winters (usually the temperature is above freezing, even though almost every year there can be a few days with snow and frosts), and cool summers, which can experience some rainfall, but are also fairly sunny.


Vancouver is the only major city in Canada which is not freezing in winter: the average temperature is 4 °C (39 °F) in January, and 18 °C (64 °F) in July, and the climate is more similar to that of London (even though summer in Vancouver is sunnier) than to that of scandinavian cities.

The south

In the Great Lakes region, in the plains of central and southern Ontario and Quebec, the climate is still continental, but it becomes also humid, with rainfall around 1,000 mm (40 in) per year, well distributed throughout the year.
After a freezing winter, characterized by dry and sunny days alternating with periods of bad weather and snowfalls, a late and very cool spring comes, and then a quite short summer, during which rainy and cool days alternate with hot and sunny days, with possible thunderstorms in the afternoon.


In Montreal, which is located at the latitude of southern France, temperatures in winter are similar to those of Moscow, Russia, with an average in January of -10.5 °C (13 °F), while summers are warm, with an average temperature of 20.5 °C (69 °F) in July.

During winter, in the Great Lakes region, cold air masses from the north-west pick up moisture when passing over the Great Lakes, and then collide with warmer air masses coming from the United States, therefore, in this area there are often waves of bad weather with heavy snowfalls.
In the southern part of Ontario, which is also the southernmost part of the country, during the summer, sometimes hot and muggy days occur, when the area is reached by hot air masses from inland areas of the United States: in these cases, the temperature can rise up to 40 °C (104 °F).

Eastern coasts

The east coast of Canada (see Nova Scotia, Newfoundland and Labrador) has a humid climate, cold and snowy in winter, mild and rainy in summer.


Here are the average temperatures in Halifax, Nova Scotia.

In Halifax, precipitation is abundant, since it amounts to 1,450 mm (57 in) per year, in fact disturbances form in all seasons, due to the continuous clash of air masses. Being on the coast of the Atlantic ocean and exposed to the south, even in mid-winter Halifax can receive southern currents, which raise the temperature above freezing and bring rainfall. Here is the average precipitation.

In Halifax, the sun is not seen very often on average, however, in July and August it shines for roughly half the time.

On the south coast of Nova Scotia, the sea does not freeze in winter, except in the most closed and sheltered bays. In summer, the sea is very cool, if not cold.
Halifax - Sea temperature
Temp (°C)2001491416151284
Temp (°F)363232343948576159544639

The most eastern and northern coasts of Newfoundland are cool or even cold even in midsummer, because of the direct influence of the Labrador Current. Here the climate is similar to that of the Sakhalin Island and the coast of the Sea of Okhotsk in the Russian Far East, and in summer it's cold and foggy. The clash between the cold sea current and the warmer waters coming from the tropical latitudes of the Atlantic, generates frequent and dense fogs. For this reason, the area of the Grand Banks is the foggiest place on Earth.

When to go

The best time to visit central and southern Canada, where the major cities are located, goes from late summer to early autumn (i.e. from late August to late September): this way you can avoid the climate extremes (both the cold winter and the possibly hot days in summer), you will find fewer mosquitoes (which in summer plague much of the country), and you can enjoy a quiet and often sunny weather (the so-called Indian summer, which sometimes lasts until October).
In addition, in late September you can admire the spectacular colours of the forests of maples and other species.
The period from late spring to early summer, i.e. late May to late June, may also be good.
The warmest period (July-August) is not totally to be avoided, although sometimes it can be hot, with some afternoon thunderstorms as well.

The worst period, along with midwinter (December to February), is perhaps that of the thaw, which varies depending on the year and the area, and occurs around April in central and southern Canada: the melting snow turns into mud and travelling becomes difficult, at least outside the cities.

In the northern regions, summer is the only period in which the temperature rises above the melting point, but travelling may be easier when all the land is frozen. At high latitudes, you can see the white nights in June, while beyond the Arctic Circle the sun never sets for a longer or shorter period, depending on latitude. At Easter, the vast northern territories are still frozen, but the days are already long enough. In winter, especially in December, the length of the day is very small.

What to pack

In winter: cold weather clothing, synthetic thermal long underwear, fleece, parka, wind jacket, warm boots; T-shirts and light shirts for warm indoor environments. For the Vancouver area and the west coast, warm clothes, coat, raincoat or umbrella.
In summer: in major cities, light clothing, T-shirts for hot days, jacket and sweater for the evening and for cooler days, raincoat or umbrella. For the Arctic region and the high mountains, and for excursions in northern seas and glaciers: warm clothes, warm jacket, gloves, raincoat.
