What Is Climate Like In Yellowknife?

Even though Yellowknife is within the Northwest Territories, which is known for being very cold, Yellowknife is not considered to be a “polar” climate. On the Koppen Climate Classification,  it is officially stated as a Dfc climate, defined as being a continental climate (D), with no dry season (f), and having a cold summer (c).

A continental climate is one of the five classifications of the Koppen Climate Classification, with the others being tropical (A), dry (B), temperate (C), and polar (E). Tropical climates are the warmest, dry climates represent places such as deserts, and polar regions are towards the far north and far south with plenty of snow throughout most of the year, making each of them distinct. However, temperate and continental both have a lot in common. Both of them generally have distinct differences between the four different seasons, both of them have extreme weather events pretty often, such as thunderstorms and even tornadoes, while lacking the extremes of the other three regions.

Tropical climates have temperatures of over 18 C (64 F) every month, dry climates fail to reach a certain precipitation threshold, and polar climates, have no month where the temperature reaches 10 C (50 F), or warmer. Both temperate and continental climates reach none of these requirements, with the difference between the two being that continental climates have at least one month where the average temperature is below 0 C (32 F). Since Yellowknife’s hottest month averages over 10 C (50 F), and its coldest month averages less than 0 C (32 F), it is considered continental.

The (f) refers to having no major difference in the amount of precipitation in summer (defined as April – September) and winter (defined as October – March). The (c) refers to a cold summer, which means that only 1-3 months will average above 10 C (50 F) in an average year, with no month averaging below -38 C (-36 F) in an average year.

The classification of a continental climate instead of a polar climate shows that Yellowknife, despite still being relatively cold, is still warmer than people think.

One thing that might surprise people about Yellowknife is the lack of snow. This is partially because summers can still be somewhat warm, with much of spring and fall still averaging temperatures above freezing.

The city also has relatively steady winds, with an average of 10-12 km/h year-round.

However, there will be a major lack of precipitation, with March generally having fewer than 5 days of snow, with each of those days having only a few centimetres each. However, things warm up surprisingly quickly, as temperatures in April will generally be about 10 C (18F) degrees warmer than in March, with similar levels of precipitation, cloud cover and humidity. The warming will continue even more in May, with highs often ranging from 5 C (41 F) to 10 C (50 F), and even lows of about freezing, with rain and snow still being rather sparse.
