Trader consensus around 21–23°C for Warsaw's July 27 maximum reflects short-range model agreement on moderate conditions following June's record heatwave, with Atlantic air and increasing cloud cover or scattered thundery showers limiting daytime heating. Official guidance from sources such as the Institute of Meteorology and Water Management (IMGW) and global ensembles shows highs near seasonal norms of 23–25°C, though afternoon convective activity could cap peaks or allow brief warmer spells depending on timing. Recent model runs emphasize wind shifts and moisture that differentiate the 21°C versus 23°C scenarios, while newer updates expected within 24–48 hours from the European Centre for Medium-Range Weather Forecasts and National Oceanic and Atmospheric Administration will clarify resolution criteria tied to the daily official maximum.
