Recent model runs from sources including the Polish Institute of Meteorology and Water Management (IMGW) and Met Office project a maximum of 26–27°C in Warsaw on August 31 under weakening high pressure, with southwesterly flow and increasing cloud cover. Light showers or variable skies could reduce peak solar insolation and cap readings near the lower end of that range, while clearer intervals would support the upper end. Ensemble spread and minor differences in timing of any frontal passage create the tight clustering around 25–27°C outcomes, as even a 1–2°C shift from boundary-layer mixing or precipitation timing can alter the daily high. Historical late-August climatology near 21–23°C underscores the current warmer anomaly but also highlights how quickly such patterns can moderate.
