Weather expert’s comment

The VDNKh weather station shows that the average annual air temperature in Moscow went up 1.5ºC, with January (up 2.4ºC) and July (up 2.6ºC) warming up quite significantly. January and February were the coldest months, while the temperature maximum was hit in July. The duration of frosts reduced and in November the average monthly temperature was positive, rather than negative as before.

Average annual precipitation in the past 15 years remained close to the norm of 1961–1990. Yet the distribution of precipitation within the year changed, with January and April becoming the driest months (in place of March). July and August are not very much different in terms of precipitation, on average. The greatest number of cases with strongest precipitation (over 16 mm during 12 hours) occurred in July and August – 24 and 22 cases respectively, in the past 15 years. Maximum daily fresh snow growth was 28 cm on March 15th, 2013, and 27 cm on December 25th, 2014. Strong frosts (with min. temperatures below -30ºC) were registered only three times; the absolute minimum (-30.8ºC) in the past 15 years was registered on January 19, 2006. The absolute maximum from 2000 to 2014 was 38.2ºC on July 29, 2010 (the former maximum of 36.8ºC was registered on August 7, 1920).

Only once during the past 15 years, in December 2010, did Moscow see a dangerous weather phenomenon – ice slick that lasted 2–3 days, the diameter of ice coating reaching 20–25 mm.
