# Severe weather and extreme temperature swings in Poland > Live situation record from CLSTR: https://clstr.news/situations/weather-patterns-in-poland > Updated: 2026-09-10T10:55:00.000Z. Sources: 65. Developments: 8. Weather patterns in Poland continued to show extreme variability during the transition from August to September 2026. On August 31, the Institute of Meteorology and Water Management (IMGW) issued first-degree alerts for several regions, including Podkarpacie, Lubelskie, Silesia, Małopolska, Łódzkie, Mazovia, and Pomerania. While much of the country faced a cooling trend, southeastern regions experienced heat alerts with temperatures potentially reaching 33°C. As September progressed, the focus shifted toward heavy precipitation and wind. On September 4, the IMGW issued first-degree warnings for intense rainfall in northern regions, including Pomerania, West Pomerania, and parts of Warmia-Masuria. Conditions escalated as second-degree alerts were issued for Lower Silesia and parts of Greater Poland and Kuyavian-Pomeranian, where wind gusts could reach up to 100 km/h. The severity of the weather resulted in a significant increase in emergency service activity, with the State Fire Service reporting over 1,700 interventions. While previous reports noted no injuries, a recent incident in Recz involving wind gusts during a local festival resulted in four injuries, with one person reported to be in serious condition. By September 8, the country remained in a state of volatility. Heat warnings covered eight voivodeships, including Mazowieckie, Podlaskie, Łódzkie, Lubelskie, Świętokrzyskie, Podkarpackie, Małopolskie, and Śląskie, with temperatures expected between 29 and 31°C. Simultaneously, severe weather alerts for southern Dolnośląskie and Opolskie warned of heavy rain (25 to 40 mm), thunderstorms, hail, and winds up to 70 km/h. This extreme heat has led to severe agricultural consequences, with farmers in regions like Opole reporting crop losses of up to 50 percent due to temperatures reaching 40°C. By September 10, meteorological forecasts indicated a significant temperature gap of up to 10 degrees Celsius across the country, driven by the interaction between a Central European high-pressure system and a moist low-pressure system from the Balkans. ## Claims - Wind gusts in the mountains can reach 90 km/h.
