Recent model consensus from agencies like the Met Office and ECMWF points to a high-pressure ridge over central Europe, delivering mostly sunny conditions and light northwesterly winds to Warsaw on August 12. These factors limit cloud cover and moisture advection, allowing surface heating from solar insolation to peak near 23–25 °C—values that align with the closely matched market-implied probabilities of 31.5 % for 23 °C and 35.5 % for 24 °C. Minor differences in forecast maxima hinge on exact boundary-layer mixing and any residual daytime cumulus, which could trim or boost the daily high by 1–2 °C. Historical August averages near 24 °C provide context, while the absence of fronts keeps resolution uncertainty low ahead of final observational data.
