March 1st marks the beginning of meteorological spring, which this year coincided with exceptionally warm weather across the entire country. Although a dense layer of clouds hangs over many cities, such as Kraków and Warsaw, thermometers show values well above the norm for this period. However, experts warn of the approaching Doreena front, which could bring local weather breakdowns and a temporary return to winter conditions.
Start of meteorological spring
The official start of the spring period in meteorological statistics falls on March 1st, coinciding with the current warming.
Extreme thermal anomaly
Temperatures in Poland exceed the norm by 15 degrees Celsius, reaching locally up to 20 degrees on the coast.
Doreena front approaching
Meteorologists warn about the impact of a new atmospheric front, which could bring cooling and rainfall.
Winter nights with warm days
Despite high daytime temperatures, nighttime drops characteristic of winter still occur, requiring vigilance.
The first day of March brings a fundamental weather shift in Poland, which meteorologists define as the start of meteorological spring. This phenomenon is characterized this year by a powerful thermal anomaly, reaching up to 15 degrees Celsius above the long-term average in some regions. The last day of February foreshadowed this trend when a surprising 20 degrees Celsius was recorded over the Baltic Sea, including in Darłowo, prompting thousands of residents to engage in outdoor activities. Crowds of walkers filled parks in Poznań, Kraków, and the coastal strip, enjoying almost summer-like weather. The synoptic situation is currently shaped by a system of anticyclones, which create a block for cold air masses from the north. Despite high daytime temperatures, synopticians point to significant diurnal variability—nights remain wintery, which is typical for the early spring period. Additionally, the Doreena atmospheric front is approaching Poland, which could bring sudden cooling. The most clouds and rainfall are currently observed in northern and western Poland, including in Szczecin, Bydgoszcz, and Sopot, where rainy weather is hindering Sunday relaxation. The concept of meteorological spring was introduced by climatologists to standardize comparative periods for weather statistics. Unlike astronomical spring, which depends on the Sun's position relative to the equator, meteorological spring always encompasses three full months: March, April, and May.Despite temporary cloudiness in the center and south of the country, the overall trend indicates a dominance of air masses with spring-like characteristics. In cities such as Łódź and Wrocław, meteorologists predict clearing skies, although the Doreena front poses a significant threat to the stability of this trend. It is worth noting that such high temperatures at the turn of February and March are being monitored for their impact on plant vegetation, which may start too early, exposing crops to damage in case of later frosts. Society is reacting to the warming with enthusiasm, as seen in the high attendance at recreational spots, but meteorological services appeal for monitoring current warnings regarding sudden frontal changes. Historical analyses by the Institute of Meteorology and Water Management indicate that February and March in Poland are becoming statistically warmer due to global climate change, manifesting in more frequent occurrences of extreme positive anomalies.
