Recent forecast guidance from major European weather models indicates a high temperature in Warsaw on August 12 most likely in the 23–24°C range, supporting the market's tight split between those two outcomes. Light northwesterly winds, mostly sunny skies, and stable high pressure are expected to limit daytime heating while preventing significant cloud build-up that could suppress maxima. Ensemble spreads remain modest at this short range, with minor divergences centered on exact boundary-layer mixing and any late-day sea-breeze influence from the Baltic. Historical climatology for mid-August places the normal high near 24°C, providing a baseline against which current model consensus sits. Updated runs from national meteorological services and satellite-derived land-surface temperatures over the next 24–48 hours represent the key data points that could shift implied probabilities before resolution.
