Recent forecasts from European meteorological models indicate Warsaw will experience mostly cloudy conditions with scattered showers on August 19, suppressing daytime heating and capping the maximum temperature near 20–22°C. This aligns with the market’s tight clustering around those outcomes, as light winds and high cloud cover reduce solar insolation compared with typical August clear-sky scenarios that often reach 23–25°C. Ensemble guidance from sources such as the ECMWF shows modest model spread, with the warmest solutions still struggling to exceed 22°C under the prevailing synoptic pattern. The implied probabilities therefore reflect both climatological context—mid-August highs averaging near 23°C—and the immediate influence of this transient moisture and cloud regime, which is expected to persist through the 48-hour forecast window.
