Current forecast models from GFS and ECMWF indicate a high near 19°C in Warsaw on August 24, driven by moderate westerly flow under building high pressure that limits strong daytime heating and keeps skies mostly cloudy. This setup favors a peak in the 18–20°C range, with minor differences in cloud timing or boundary-layer mixing determining whether the maximum reaches 19°C or edges toward 20°C. Recent cooler air advection following Saturday’s showers has lowered baseline temperatures, while low precipitation chances reduce evaporative cooling effects. Traders weigh these variables against historical late-August averages near 22°C, with updated model runs expected to refine the exact outcome before resolution.
