Recent forecasts from agencies including the Met Office and timeanddate place Warsaw’s June 13 high near 20–21 °C under mostly cloudy skies with isolated showers, keeping trader focus on the narrow 19–21 °C cluster. Persistent mid-level moisture and modest west-to-northwesterly flow are expected to cap daytime heating, while limited insolation prevents stronger warming that would favor 22 °C or higher. These conditions align with typical early-June variability in central Poland, where afternoon convection often trims maxima by 1–2 °C relative to clear-sky potential. Updated model runs through the weekend will refine timing of any showers and confirm whether the peak settles at 19 °C or edges to 21 °C before market resolution.
