If you want to spend the new year or Christmas holidays in St. Petersburg, see what the weather will be like in the Northern capital for the New year 2021 and Christmas, as well as when the forecast promises severe frosts and thaws.
Geography and climatic features of the region
The climatic features of St. Petersburg are determined by a number of factors, including::
- geographical location;
- proximity to large bodies of water;
- features of atmospheric circulation.
The Leningrad region is located in the transition zone from a continental to a marine climate, which is characterized by frequent changes in weather conditions, rains, fogs and strong winds.
Continental air masses bring dry, warm weather to the Leningrad region, while moist sea air comes from the Atlantic ocean, which slightly softens the climatic conditions.
For the St. Petersburg winter, the following are typical::
- freezing rain;
- icy conditions;
- snow and blizzards (with or without snow cover formation);
- strong winds;
- sudden change in the weather.
The absolute minimum of winter temperatures recorded in the region is -35.9 ° C, although in recent years such extreme frosts have not been recorded in the city. The average winter temperature in St. Petersburg varies between -8 … -12 ° C with short periods of severe frosts, approaching -20 ° C at night.
Although according to the climatogram, the maximum amount of precipitation in the region falls in the summer, in winter in St. Petersburg, the weather quite often presents surprises in the form of snow or freezing rain. According to weather forecasters, the height of snow cover can reach 73 cm, but on average it is 25-30 cm.
General forecast for winter 2021
Predicting what the weather will be like in St. Petersburg for the New Year 2021 is quite difficult, due to the changeability and instability of the meteorological picture of the region.
For the Leningrad region, the beginning of meteorological winter falls in the second half of November, although the first frosts and snow are possible at the beginning of the month and even at the end of October. Sometimes the snow cover forms as early as December, but there are also years with frequent thaws that lead to wet weather, freezing rains and ice.
Autumn 2020 was relatively warm. The first frosts and snow came to the region only at the end of November. According to forecasts of meteorologists, the winter of 2021-2022 will also be warm, without extreme frosts and cataclysms, which means that we should expect frequent thaws and most likely the weather for the New Year 2021 in St. Petersburg will be wet and snowless.
It is worth noting that the processes of global warming have not spared the Northern capital. The climate here is also undergoing changes. In recent years, the average winter temperature has increased, the thaw periods have become longer, and the snow cover is formed somewhat later than normal.
