Climate and monthly weather forecast
Oymyakon, Russia

Oymyakon, located in the northeastern part of Russia, endures the climate condition known as Dfd in the Köppen climate classification. This classification indicates that the region experiences a subarctic climate, characterized by very severe and cold winters, cool summers, and an absence of a dry season. It's a climate type prevalent in areas situated far away from the temperate influence of the ocean, where bitter winters and brief summers are a norm.

A glance at the temperature data reveals a stark contrast between the warmest and coldest months. January tends to be the chilliest with average high temperatures plummeting to -42.5°C (-44.5°F). Even the warmest month, July, witnesses a temperature range from 6.2°C (43.2°F) to 22.7°C (72.9°F), only slightly grazing the classification of a warm summer. On the other hand, there is a variation of rainfall patterns. July has the most rainfall with 45mm (1.77"), while March observes the least with 5mm (0.2"). Further, July also experiences the greatest number of rainy days, 8.7 on average, in direct contrast to March which only typically experiences rainfall on 1.4 days.

Sunshine and daylight hours also reflect this climate's drastic oscillation between seasons. During June, the region receives over 20 hours of daylight and 10.1 hours of sunshine. Conversely, December only gets 4.7 hours of daylight and a mere 0.4 hours of sunshine.

The peak of summer, specifically between June and August, may offer the most hospitable conditions for visitors. With temperatures ranging from 4°C (39.2°F) to 22.7°C (72.9°F), the weather is less harsh compared to other months. Rainfall does reach its highest point, but the longevity of daylight, from 19.3 hours to 20.4 hours, and sunshine, from 9.6 hours to 10.1 hours, can offset the increased precipitation. Travelers who are not accustomed to extreme cold may find this period most favorable for visitation.
