**Current ensemble forecasts from global models position the daily maximum in Warsaw on August 20 near 23–24 °C, driving the market’s tight clustering around those outcomes.** Short-range guidance, including runs from the European Centre for Medium-Range Weather Forecasts, shows modest warm-air advection under generally stable conditions with scattered cloud cover and light winds, limiting strong daytime heating. This aligns with the seasonal late-August decline in solar insolation over central Poland and produces the observed 38.5 % implied probability on 24 °C, 28 % on 23 °C, and 26.5 % on 25 °C or higher. Traders are weighting the narrow spread between these bins because small shifts in cloud timing or boundary-layer mixing could push the peak across the 24–25 °C threshold, while cooler scenarios remain low-probability given the absence of strong northerly flow or significant precipitation in the latest model consensus. Updated model runs and official guidance from national meteorological services will continue to refine these odds through the final 48 hours.
