The turn of February and March brings Poland a sudden warming, resulting in numerous hydrological warnings. The Institute of Meteorology and Water Management alerts about the exceedance of warning levels on rivers in Pomerania and Masovia, including a critical situation on the Mławka River. Simultaneously, farmers across the country assess the condition of winter crops after the frosty winter, struggling with water stagnation in fields that threatens future yields.
Hydrological alerts in the country
Exceeded alarm levels on the Mławka River and warnings for Pomerania and Żuławy due to rapid snowmelt.
Difficult situation in agriculture
Water stagnation in fields threatens winter crops, requiring farmers to take quick regenerative and fertilization actions.
Spring revival in cities
Rich cultural and sporting offerings in major Polish cities at the turn of February and March.
The ending winter of 2026 leaves behind a complex hydrological situation and challenges for the agricultural sector. Although January was recorded as one of the driest in the 21st century, heavy snowfall in February and sudden warming led to rapid river swelling. The most difficult situation is in Masovia, where the Mławka River exceeded the alarm level, resulting in a red alert being issued. Similar threats are being monitored in Pomerania and in the Żuławy region, where residents fear flooding due to the accumulation of meltwater. IMGW regularly updates hazard maps, indicating possible exceedances of warning levels in coastal river basins. This year's vegetation of plants, although theoretically supplied by water from melting snow, encounters difficulties. In many fields, especially in the Świętokrzyskie and Greater Poland regions, water stands in terrain depressions, which can lead to the suffocation of winter crops. Agricultural experts now recommend quick plant viability tests and precise planning of the first dose of nitrogen fertilization to save the yield potential of wheat and rapeseed. Historically, the Vistula Żuławy is one of the areas in Poland most vulnerable to floods, where drainage systems and pumping stations have been operating continuously since the time of Olęder settlement in the 16th century. Despite hydrological threats, the weekend of February 28 – March 1 encourages outdoor activities. Cities such as Kraków, Wrocław, Toruń, and Gdynia have prepared a wide range of cultural and sporting events. In Gdynia, a special event is the visit of a French frigate, whose crew is enjoying a few days of rest in the Polish port. Meanwhile, in the consumer sphere, economists noted an unusual spike in sales of winter clothing and footwear, which was a direct societal reaction to earlier extreme frosts that surprised the market after several milder seasons. 10% — by how much wheat yield can be increased through tillering It is also worth noting unusual phenomena outside the country's borders that may affect tourism. Reports of a locust invasion on European islands are causing concern among travelers, although in Poland itself, attention is focused on local nature and garden protection. Specialists warn against mowing lawns too early, pointing out that the soil must reach an appropriate temperature after the snow cover recedes for plant regeneration to proceed in an optimal manner.
