Introduction

In the endless territory of Asian Russia, the climate is characterized by frigid winters: in fact, the coldest inhabited places in the world are found here. Moreover, if we exclude the northernmost part, where the climate is Arctic or sub-Arctic, and partly the east coast which has a cold maritime climate, summer is mild to warm in most of the territory because of the strong continentality, and it can sometimes even get hot.
The average temperature in January is almost everywhere below -10 °C (14 °F), and it goes down to -45 °C (-49 °F) in the Eastern inland areas. The daily average in July is around freezing (0 °C or 32 °F) on the northern islands and along the Arctic coast, while it goes up to 20 °C (68 °F) in the southernmost areas.
During winter, in most of the territory, the powerful Siberian Anticyclone dominates, except in the eastern seas, where the clashes between continental and maritime air masses give rise to intense low pressure areas, which can bring heavy snowfalls. In the vast plains, in the West Siberian Plain but also in the valleys of the Central Siberian Plateau and of Yakutia, cold air stagnates to the soil, and the sky is often gray, with frequent light snowfalls, while cold outbreaks from the Arctic may lead to raging gusts of blizzard.
During the long winter months, precipitation is scarce almost everywhere because of the cold: snowfalls are frequent but light, and the snow can be carried away by the wind. Owing to the greater availability of heat and energy, summer is almost everywhere the rainiest season, in fact, afternoon thunderstorms may occur in inland areas. On the other hand, the south-eastern areas receive even more rainfall in summer because they are affected by the Asian monsoon. In most of Siberia, yearly precipitation is between 150 and 500 millimeters (6 and 20 inches). In the far east, the Kamchatka peninsula is the wettest region of mainland Siberia: in some areas, precipitation exceeds 1,000 mm (40 in) per year, and a lot of snow can fall in winter.
Southwest of Kamchatka, the Kuril Islands are even wetter, since precipitation reaches 1,500 mm (60 in) per year. Here, winters are snowy and stormy; in fact, there's a strong clash between frigid air masses coming from continental Siberia and mild air masses coming from the subtropical latitudes of the Pacific. Summers in the Kurils are very cool because the sea is still cold after the long winter months, and are quite rainy as well.

The Pole of Cold

---

The Siberian winter gets colder from west to east, since the western part and especially the European part of Russia are more often affected by currents of Atlantic origin. In the Republic of Yakutia (or Sakha), located in the eastern part, there is an area where the January average is below -40 °C (-40 °F) and the coldest records go down to -70 °C (-94 °F).
The coldest city is Oymyakon, located in the upper Indigirka Valley, on the 63rd parallel and at 700 meters (2,300 feet) above sea level, where the coldest record is as low as -71 °C (-96 °F). Another very cold city is Verkhoyansk, located more to the north but at sea level, in the Yana River Valley, where the coldest record is -70 °C (-94 °F), or according to other sources, -68 °C (-90 °F); here, the average ranges from -44,5 °C (-48 °F) in January to 16.5 °C (61.5 °F) in July. The highest recorded temperature in Verkhoyansk is 38 °C (100 °F), so the difference between the two records exceeds 100 degrees Celsius!
This area is the "Pole of Cold" of the Northern Hemisphere, in fact, it's colder than the North Pole, and it's surpassed only by the central area of Antarctica. At these temperatures, a human being is likely to freeze in a few minutes, if not properly covered, while buildings tend to become brittle because of the cold.

Oymyakon

As mentioned, Oymyakon is located at 700 meters (2,300 feet) above sea level, even though the airport, where the meteorological data are taken, is located 30 km (18 mi) to the south-east, near the town of Tomtor, 750 meters (2,460 feet) above sea level.
The coldest record is -71.2 °C (-96.2 °F) and was set in January 1924. In the postwar period, the lowest temperatures in Oymyakon were -65.4 °C (-85.7 °F) in January 1973 and -64.6 °C (-84.3 °F) in February 2002. The coldest month was January 1967, with a daily average of -53.1 °C (-63.4 °F).
Summer is mild during the day, with cold nights, however, there may be short warm periods. On the hottest days of the year, the temperature typically reaches 30 °C (86 °F). The highest record is 34.6 °C (94.3 °F) and was set in July 2010.
At night, the temperature can drop below freezing even in summer. For example, in 2020, it dropped to -4.5 °C (24 °F) in late July and -10 °C (14 °F) in late August.
In the past, temperatures were lower: in the thirty years 1951-1980, the average minimum in January was -52 °C (-61.5 °F), the average maximum was -43.5 (-46.5 °F). Here are the average temperatures.

Precipitation in Oymyakon is scarce during the long winter months because of the cold; it's no wonder that the rainiest season is summer, when, however, the rains are not abundant. Here is average precipitation.

The sun in Oymyakon is rarely seen from November to January, also because of the short duration of the day, while in spring, it shines for a fair amount of hours, both because of the length of the day and of the low number of rainy days. Here are the average sunshine hours per day.

Yakutsk

In Yakutsk, the capital of Yakutia, at 62 degrees north latitude on the Lena River, is the coldest city of some importance in the world.
The average temperature ranges from -37 °C (-34.5 °F) in January to 19.5 °C (67 °F) in July. The weather station was already in operation at the end of the nineteenth century. The coldest record is -64.4 °C (-83.9 °F) and was set in February 1891. After the war, the coldest record is -60.3 °C (-76.5 °F), set in January 1951.
On the hottest days of the year, the temperature typically reaches 34 °C (93 °F). The highest record is 38.4 °C (101.1 °F) and was set in July 2011.
Over the past hundred years, the temperature has risen a lot, especially in winter. From 1891 to 1920, the daily average in January was -46.2 °C (-51.1 °F), while from 1951 to 1980, it was -42 °C (-43.6 °F). Here are the average temperatures.

In an average year, 240 mm (9.5 in) of rain or snow fall, with a maximum of 40 mm (1.6 in) in July and a minimum of just 8/10 mm (0.3/0.4 in) per month from December to March, of course not in the form of rain but of light snow. The amount of sunshine from May to September is slightly higher than in Oymyakon.

North coast and islands

---

Along the northern coast overlooking the Arctic Ocean, the average in January and February is around -20 °C (-4 °F) in the west, it goes below -30 °C (-22 °F) in the central and eastern part, and it rises again to around -25 °C (-13 °F) in the far east, and to -20 °C (-4 °F) in the Bering Strait, which separates Siberia from Alaska. In the arctic regions, the lowest records hover around -45/-47 °C (-49/-53 °F), which means that they are not lower than those of the southern part of Siberian mainland.
In Tiksi, on the northern coast of the Sakha Republic (therefore, in the coldest part of the coast, the central-eastern one), the average temperature ranges from -30.5 °C (-23 °F) in February to 8.5 °C (47.3 °F) in July. The summer temperatures, low but above freezing, make it an example of the subarctic climate.
From November to February, the temperature never exceeds freezing. In February 2013, the temperature dropped to -49.5 °C (-57 °F). In summer, short warm periods can occur, perhaps only a day or two, in which the temperature can reach 28/30 °C (82/86 °F). In July 1991, it reached 34.3 °C (93.7 °F).
Here are the average temperatures.

At these latitudes, the sun from November to January does not even rise; the sunniest season is spring (in April, there are 9 sunshine hours out of 22 daylight hours per day), while in summer, the sun becomes less frequent, as cloudy and rainy days increase.

The sea is frozen solid from November to May; remember that being salted, sea water freezes at about -2 °C (28.5 °F).

During summer, temperatures remain around freezing (0 °C or 32 °F) on the northernmost islands (where the climate is arctic), they are around 3/4 °C (37/39 °F) along the northern coast, and go up to 10 °C (50 °F) a few hundred kilometers to the south (this value is regarded as the limit of the subarctic climate). The highest recorded temperatures are around 10 °C (50 °F) on the Arctic islands, and around 15/20 °C (59/68 °F) along the northern coast of the continent. Precipitation is scarce in winter, when it occurs in the form of light snow, and it's more abundant in summer, when it can still occur in the form of snow on the northernmost coasts and islands.
In Golomyanniy Island, located at a latitude of 79 degrees north, and belonging to the group of the Severnaya Zemlya (Northern Land), the climate is arctic. On the coldest nights of the year, the temperature typically drops to -40 °C (-40 °F). The coldest record is -50.7 °C (-59.3 °F) and was set in March 1969. On the warmest days of the year, the temperature typically reaches 6/7 °C (43/45 °F). The highest record is 11.5 °C (52.7 °F) and was set in August 2020. Here are the average temperatures.

The southern cities

---

In the southern plains, where we find the major cities, which are located along the Trans-Siberian Railway, the climate is strongly continental, but more forgiving than the northern areas, not so much for the lowest records, which are very low here as well, but for the warmer and longer summer.

Yekaterinburg

For example, in Yekaterinburg, the former Sverdlovsk, at 56 degrees north latitude near the Ural Mountains, the average temperature ranges from -14 °C (7 °F) in January to 19 °C (66 °F) in July. In winter, the temperature has dropped to -41 °C (-42 °F) in recent decades, albeit after the war the coldest record is -46.7 °C (-52.1 °F), set in December 1978.
In summer, on the hottest days the temperature typically reaches 32/33 °C (90/91 °F), although it reached 38 °C (100.5 °F) in July 2012 and 37 °C (98.5 °F) in August 2021.
Here are the average temperatures.

In a typical year, 500 mm (20 in) of rain or snow fall, with a maximum of 70 mm (2.8 in) in July and a minimum of around 10 mm (0.4 in) from December to March. Snowfall occurs from October to April. Here is the average precipitation.

The sun in Yekaterinburg is not so rare in spring and early summer.

Omsk

Further to the east, in Omsk, at 54 degrees north latitude on the banks of the Irtysh River, the climate is even more continental: the average temperature ranges from -17.5 °C (0.5 °F) in January to 19 °C (66 °F) in July. From 1991 to 2020, the extremes were -42.3 °C (-44 °F) and 37.5 °C (99.5 °F). Here are the average temperatures.

Being that Omsk is located in the arid zone of Central Asia, precipitation decreases to 390 mm (15.3 in) per year, even though it maintains the same pattern, with a winter minimum and a summer maximum. Here is the average precipitation.

In Omsk, the amount of sunshine is even higher in spring and summer, and there are as many as 10.5 hours of sunshine per day in June and July.

Further to the east, in Novosibirsk and Krasnoyarsk, the climate is similar to that of Omsk, but we enter the area affected by the Asian monsoon, which receives a little more rain in summer, in fact, precipitation slightly increases, and exceeds again 400 mm (16 in) per year.
Further to the east, in Irkutsk, near Lake Baikal, 500 meters (1,600 feet) above sea level, the average ranges from -19 °C (-3 °F) in January to 18 °C (64 °F) in July. Precipitation amounts to 410 mm (16 in) per year; the cold record of the last thirty years is -46 °C (-51 °F).
In eastern Siberia, north of China, the effect of the summer monsoon is more noticeable, so much so that rainfall exceeds 100 mm (4 in) in the month of July.

Blagoveshchensk

In Blagoveshchensk, at 50 degrees north latitude, on the Amur River and near the border with China, the average temperature ranges from -20.5 °C (-5 °F) in January to 22.5 °C (72.5 °F) in July. The records of the last thirty years are: -45 °C (-49 °F) the lowest, and 39 °C (102 °F) the highest.

Here, precipitation amounts to 575 mm (22.6 in) per year, with a pronounced minimum from December to February of less than 10 mm (0.4 in) per month, and a maximum in July and August of 130/135 mm (5.1/5.3 in) per month. Here is the average precipitation.

In this eastern part of Siberia on the border with China, winter is quite sunny, while in summer and until September, the sky becomes cloudy with some frequency because of the summer monsoon.

Eastern coasts and islands

---

In the long eastern coastline, the presence of the sea makes the climate more temperate, in fact, winter is less frigid, while summer is cold (or at least cool) and wet. In winter, cold currents carry drifting ice towards the island of Hokkaido in Japan. During summer, fog is frequent in the central and northern areas. Because the sea warms up more slowly than in the mainland, if we exclude the northernmost area, August is, albeit slightly, the warmest month.
South of the Bering Strait, the coast bordering the Bering Sea has a subarctic climate, with long, cold winters and very cool summers; the average in July and August is around 10 °C (50 °F).

Anadyr

In the northeast, in Anadyr, in the gulf of the same name, at a latitude of 64 degrees north, the average temperature ranges from -22 °C (-7.5 °F) in January to 12.5 °C (54.5 °F) in July. From 1991 to 2020, the extremes were -44 °C (-47 °F) and 29 °C (-20 °F). From 1991 to 2020, the extremes were -37 °C (-34.5 °F) and 27 °C (80.5 °F). Precipitation amounts to 385 mm (15 in) per year, with the usual summer maximum. The city is located in a sheltered bay, but along the coast of the Bering Sea, annual precipitation generally exceeds 500 mm (20 in). Here are the average temperatures.

In this northern part of the Bering Sea, the sea remains frozen solid from January to March, while it is partially frozen (also depending on the year) in December, April and May.

Magadan

Further south, in Magadan, in the Sea of Okhotsk, at a latitude of 59 degrees north, the average temperature is between -15.5 °C (4 °F) in January and 12.5 °C (53.5 °F) in July and August. Winter is cold and dry because the wind in this season blows from the continent, while later it picks up moisture from the sea and bring snowfall over Kamchatka. Annual precipitation amounts to 550 mm (21.5 in), with a maximum of 85 mm (3.3 in) in August. Snowfalls occur from October to May, but they are not abundant because, as we mentioned, the winter is dry. Here are the average temperatures.

In Magadan, the sunniest months (albeit slightly) are March and April, while later, from May to September, there is a certain number of days with rainfall or even fog.

Petropavlovsk

In Petropavlovsk-Kamčatskij, at a latitude of 53 degrees north, on the southeastern coast of the wet peninsula of Kamčatka, the average temperature ranges from -6.5 °C (20 °F) in January to 14.5 °C (58 °F) in August. From 1991 to 2020, the extremes were -25.5 °C (14 °F) and 30 °C (86 °F).

Precipitation amounts to 1,330 mm (52.5 in) and is frequent throughout the year, which means that there are heavy snowfalls in winter. The wettest season, however, is autumn. Here is the average precipitation.

In Petropavlovsk, there is not much sun all year round because of the disturbances that frequently pass over the area.

Near Petropavlovsk, the sea, close to the freezing point in winter, remains cold even in summer, reaching only 12 °C (53.5 °F) in August.

On the island of Sakhalin, summer is a bit warmer, while winter is still very cold, with heavy snowfalls. In summer, owing to the effect of the Asian monsoon, rainfall exceeds 100 mm (4 in) per month; occasionally, the island may be affected by typhoons, tropical cyclones coming from Southeast Asia.
Here are the average temperatures in Yuzhno-Sakhalinsk.

Vladivostok

In Vladivostok, on a small peninsula in the Sea of Japan, in the southernmost part of Siberia (at 43 degrees north latitude), the average temperature ranges from -11.5 °C (11.5 °F) in January to 20.5 °C (69 °F) in August.

In Vladivostok, the summer rains are abundant, so much so that in August, 155 mm (6 in) of rain fall. The winter is dry and sunny, but also swept by dusty winds from Mongolia. However, precipitation amounts to 800 mm (31.5 in) because of the summer rains. This coastal area too, can occasionally be affected by typhoons in August and September, although when they arrive here, they are weaker than they were in the tropical seas. Here is the average precipitation.

The sun in Vladivostok is often seen in winter, while in summer, cloudy days are frequent because of the monsoon.

Unlike in the rest of Siberia, the sea near Vladivostok warms up in summer, and it becomes almost acceptable for swimming, especially in August.
