Trader consensus around 26–28°C for Warsaw’s July 15 maximum reflects the latest ECMWF and GFS ensemble guidance, which show a moderate westerly flow advecting Atlantic air masses under partly cloudy skies. Model spreads arise mainly from differences in boundary-layer mixing and afternoon convective cloud development that could cap peak readings near 25–26°C or allow brief clearing to push values toward 28°C. This aligns with climatological normals of 24–26°C for mid-July and follows the late-June heatwave that elevated baseline soil and boundary temperatures. Updated model runs and satellite observations through July 14 will refine the precise thermal maximum ahead of market resolution.
