In early February, Lithuania has recorded instances of severe frost (≤-30 ºC), marking a noteworthy climatic event this winter. Historical meteorological data indicate that significant frost phenomena in Lithuania typically occur between the second half of December and early March. This has led to curiosity about the earliest and latest recorded occurrences of frost during the year, as scientists share insights from historical observations to better understand these weather patterns.

The latest occurrence of frost was observed on March 8, 1964, in Varėna, where temperatures plummeted to an impressive -37.5 °C, which remains the absolute record for the lowest temperature recorded in March. In contrast, the earliest frost recorded in Lithuania was on December 18, 1978, when temperatures reached -30.4 °C in Varėna. This highlights a relatively small window for frost occurrences in Lithuania, emphasizing the rarity of such extreme weather conditions outside the winter months.

Interestingly, within the month of December, frost has only been recorded on 7 out of 31 days, constituting approximately 23% of the total days in the month. This statistic underlines both the limitations and occurrences of frost within the country’s meteorological history, leading to discussions about climate patterns and potential implications of changing weather in the region as seasonal temperatures fluctuate more dramatically than in previous decades.
