Seymchan (Russian: Сеймча́н, IPA: [sʲɪjmˈtɕan]) is an urban locality (an urban-type settlement) and the administrative center of Srednekansky District of Magadan Oblast, Russia.

[6] [7] The town lies on the right bank of the Seymchan River, near its confluence with the Kolyma, about 350 kilometers (220 mi) north of Magadan.

Winters are extreme due to the influence of the persistent Siberian High in the months of low sun, although not as cold as Dfd climates such as Oymyakon, Delyankir, Verkhoyansk etc.

As a result, it can technically be classified as Dsc, bordering on the extremely rare Dsd subtype under Köppen Climate Classification.

Commercial flights from Seymchan to nearby remote areas using the local forest fire protection service's Mi-8 helicopters are routine.
