The weather in the ETR, especially in its eastern regions, was somewhat warmer than usual in the first decade of October. Transient colds came at the time of transition from the first to second decade and forced the air temperature to drop below zero in some places. But in the second decade, the warmth came back and was most intensive in the Russian North where new daily maxima of air temperatures were reported en masse. This anomalous warmth persisted over the whole ETR until the end of the month, accompanied with new record-breaking temperatures in the north-east (in Karelia and in the Leningrad Region).

In the Urals, the temperatures remained above-normal for almost the entire month. In the south of Siberia and of the Far East, the weather was abnormally cold at the beginning of the month, with new daily temperature minima recorded in a number of locations. In the Khabarovsk and Trans-Baikal Territories, the decade-averaged temperature in the first decade turned out to be 2-3° lower than normal. Similar to the ETR, the east of Russia in the second half of the month was hit by anomalous heat that begot new records established both in the north and in the south of Siberia, as well as in Yakutia: in these areas, the decade-averaged temperatures were 8-10° higher than normal.
