Traders have overwhelmingly positioned around 13°C as Warsaw’s maximum temperature on May 17, driven by the latest European Centre for Medium-Range Weather Forecasts model runs showing a stable high-pressure system and northerly flow limiting daytime warming. Official observations from the Polish Institute of Meteorology and Water Management align with this range, placing the current peak near the historical May average of 15–18 °C but tempered by recent cool advection. Resolution hinges on the final 24-hour maximum recorded at the central Warsaw station, with any unexpected increase in solar radiation or southerly winds the only realistic factors that could push readings to 14 °C or higher.
