Olyokminsk

Olyokminsk (Олёкминск; Өлүөхүмэ, Ölüöxüme) is a town and the administrative center of Olyokminsky District in the Sakha Republic, Russia, 651 km southwest of Yakutsk, the capital of the republic. As of the 2010 Census, its population was 9,494.

History
It was founded in 1635 as an ostrog by the Cossacks led by Pyotr Beketov, sited on the left bank of the Lena opposite the mouth of the Olyokma River. The outpost was later moved a few kilometers upstream, to a location less prone to flooding in spring.

As the junction for river traffic on the Lena and Olyokma, it was the base for Russian expeditions further east and eventually became a trade center on the river route to Yakutsk. Town status was granted to it in 1783.

Decembrists Nikolay Chizhov and Andrey Andreyev were exiled here.

During World War II, an airfield was built here for the Alaska-Siberian (ALSIB) air route used to ferry American Lend-Lease aircraft to the Eastern Front.

Climate
Olyokminsk has a subarctic climate (Köppen climate classification Dfc). Winters have temperatures averaging from -34.6 to -26.6 C in January, while summers have average temperatures from +12.0 to +24.9 C in July. In the summer months of June, July, and August, it is not uncommon for temperatures to surpass +30 C during the day. Precipitation is significantly higher in summer than at other times of the year. Although summers are similar to republic capital Yakutsk, winters are less severe courtesy of the lower latitude. As a result, Olyokminsk is rare for the Sakha Republic cities in that it has recorded above-freezing temperatures during January and February. Those episodes are rare and very short-lived.

On August 6, 1986, Olyokminsk recorded its highest ever temperature of +37.7 C. The record low for Olyokminsk was −60.1 C in 1907. July is the only month when temperatures never dropped below 0 C and December is only month when temperatures have never reached 0 C.
