With an intensely continental [[subarctic climate]] ([[Köppen climate classification]] ''Dfc'', closely bordering on ''Dfd'', [[Trewartha climate classification|Trewartha]] ''Ecbd''), Yakutsk has the coldest winter temperatures for any city its size or larger on Earth. Average monthly temperatures in Yakutsk range from {{cvt|+19.9|C}} in July to {{cvt|-37.0|C}} in December. Yakutsk is the largest city built on continuous [[permafrost]],<ref>{{Cite web |title=Вечная мерзлота и современный климат (geo.web.ru) |url=http://geo.web.ru/db/msg.html?mid=1159815&uri=index.htm |access-date=2018-12-09 |website=geo.web.ru |language=ru}}</ref> and many houses there are built on concrete [[Deep foundation#Pile foundation systems|piles]].

The lowest temperatures ever recorded on Earth outside [[Antarctica]] and [[Greenland]] have occurred in the basin of the [[Yana River]] to the northeast of Yakutsk. Winters are extremely cold and long, Yakutsk has never recorded a temperature above freezing between November 10 and March 14. Summers are sunny, warm and occasionally hot (though short), with daily maximum temperatures exceeding {{cvt|+30|C}}, making the seasonal temperature differences for the region the greatest in the world at {{cvt|102|C-change}}.<ref name="Guinness">{{Cite web |title=Greatest temperature range on Earth |url=https://www.guinnessworldrecords.com/world-records/greatest-temperature-range-on-earth |website=Guinness World Records}}</ref> The lowest temperature recorded in Yakutsk was {{cvt|-64.4|C}} on February 5, 1891, and the highest temperatures {{cvt|+38.4|C}} on {{nowrap|July 17}}, 2011, and {{cvt|+38.3|C}} on {{nowrap|July 15}}, 1942. The hottest month in records going back to 1834 has been July 1894, with a mean of {{cvt|+23.2|C}},<ref name="pogodaiklimat.ru" /> and the coldest, January 1900, which averaged {{cvt|−51.4|C}}.<ref>{{Cite web |title=Погода в Якутске – климатический монитор за январь 2001 года |url=http://www.pogodaiklimat.ru/monitor.php?id=24959&month=1&year=2001 |website=www.pogodaiklimat.ru}}</ref> Yakutsk is the largest city in the world with an average winter temperature of below {{cvt|-30|C|F}}.{{citation needed|date=July 2020}}

Yakutsk is an inland location, being almost {{cvt|1000|km|mi}} from the Pacific Ocean, which coupled with the high latitude, means exposure to severe winters and lack of temperature moderation. July temperatures soar to an above-normal average for this latitude, with the average being several degrees hotter than more southerly Far East cities such as [[Vladivostok]] or [[Yuzhno-Sakhalinsk]]. The July daytime temperatures are even hotter than some maritime subtropical areas. The warm summers ensure that Yakutsk, despite its freezing winters, is far south of the [[tree line]]. In winter, Yakutsk instead is between {{cvt|35|C-change}} and {{cvt|40|C-change}} colder than the mildest cities on similar latitudes in [[Scandinavia]].<!-- Tórshavn and Ålesund among others. -->

The climate is quite dry, with most of the annual precipitation occurring in the summer months, due to the intense [[Siberian High]] forming around the very cold continental air during the winter. However, summer precipitation is not heavy since the moist southeasterly winds from the Pacific Ocean lose their moisture over the coastal mountains well before reaching the Lena Valley.
