In Lithuania, meteorological reports reveal that February 2023 was approximately 5 degrees Celsius colder than the average, marking it as one of the coldest in recent years. The average monthly air temperature in Vilnius reached -7.1 °C, while in Klaipeda, it stood at -6.1 °C, with many days experiencing temperatures below the long-term average. Notably, the sun's shining duration increased by 1.6 times compared to the average for February between 1991 and 2020, indicating a unique climatic pattern for the month.

Most notably, the frequency of cold days was considerably higher, with Vilnius recording 18 days and Klaipeda 23 days where temperatures fell below the norm. The warmest days during February were observed between the 12th to 13th and the 22nd to 28th, while the coldest periods stretched from February 1st to 5th, 9th to 10th, and 15th to 17th. This unusual cold snap has raised questions among meteorologists regarding the broader climatic trends affecting the region.

Precipitation levels in Lithuania were notably low for February, amounting to approximately 55% of the monthly norm or around 23 mm. The scarcity of rainfall is attributed to the predominance of colder weather conditions. There were significant disparities in precipitation across different regions of the country, with some areas receiving up to 3-4 times less rain than others, particularly in the southeastern regions compared to central and northeastern parts, where moisture levels were higher. This uneven distribution of weather conditions highlights the variability and unpredictability of Lithuania's winter climate.
