According to D.Valiukas, the years 2019-2020 were especially warm. Winter is 2020 autumn: both seasons were the warmest during the period of regular meteorological meteorological observations, and the scientist said that he does not remember a year when the temperature in Lithuania would never fall below -15 degrees during winter.
Although, said D.Valukas, it is not expected that last year’s anomaly will become a trend and snow will become an extremely rare phenomenon in winter, it is not worth accepting that there will be less snow in winter and a layer of shorter snow.

With D.Valiukas 15 minutes He talked about 2020 from a climate perspective – how exceptional this year’s weather was and what to expect in the future.
– In the summer, there were articles in the media that 2020. may become the warmest year in the history of Lithuania for the entire observation period. Although the year is not overThe interview took place on December 29, – ed. past.)Can you already say in a preliminary way if this will be the case?
– Although it is too early to answer this question fully, yes, it seems that they will become the hottest year in history.
It will be possible to say quite precisely at the beginning of January, when we will have the whole year, but it is already clear that this year was the warmest or one of the warmest. But it will probably be the hottest.
Before that, the warmest year in history for the entire meteorological observation period was last year in 2019.
At that time, the average annual air temperature in Lithuania was 8.8 degrees Celsius, or 1.9 degrees higher than the perennial average in 1981-2010. air temperature.
Thus, already last year, the multiannual average was significantly exceeded. And this year, it looks like it will be a little warmer than last year. But, as I mentioned, this is not yet an official confirmation.
– What interesting trends, exceptional extremes were the weather this year?
– Two very interesting trends can be distinguished. The first particularly striking trend is last winter, which is very warm. Winter has been the warmest in the entire history of meteorological observations. There was also almost no snow in the winter, there was only very little.
The winter was warm, without snow, there were no days with very low temperatures. Usually in Lithuania there are at least a few days every winter when the lowest recorded temperature is below -20 degrees.
In the last 5-6 years, there has not been a single winter until the temperature in some part of Lithuania does not drop below -20 degrees.
And this year there were not such low temperatures: the lowest temperature recorded this year was -11.9 degrees in Varėna. And that temperature was not recorded even in winter, but on March 24, so already in spring.
Here it may be interesting to remember that, in general, the record for low temperatures recorded in Lithuania is -42.9 degrees in 1956. February 1 In Utena. So that contrast of the absence of cold is even very high.
In terms of heat, there were no such high contrasts. The highest fixed temperature in Lithuania this year was 32.3 degrees in Klaipeda on June 18. And in general, the temperature record in Lithuania, recorded in 1994. in July, is 37.5 degrees.
So it wasn’t close to the record. Although high temperatures were recorded in Lithuania in the summer, when the temperature exceeded the 30-degree limit for three days in a row, the 35-degree limit was not reached in Lithuania this year.
The second interesting trend was last fall’s ultra warm. Throughout the fall, there were very few negative temperatures, few nights where the temperature dropped below 0 degrees. Although the temperature fluctuated, it stayed above 0 degrees most of the time.

As a result, the end of the vegetative vegetation in the fall was extremely late, happening in mid-November. You will probably remember that there were many photos with flowering plants, mushrooms or raspberries both in the media and on social media in mid-November.
