Trader consensus on Polymarket overwhelmingly favors 11°C as Warsaw's highest temperature on March 20, driven by converging forecasts from authoritative models like ECMWF and GFS, which project daytime highs peaking at 11°C amid cloudy skies and light winds. Polish Institute of Meteorology and Water Management (IMGW) observations align with this, showing recent March baselines around 8-12°C, with current upper-air patterns suppressing warmer advection. Ensemble predictions show over 90% agreement within 1°C of 11°C, reflecting high short-range forecast skill for mid-latitude Europe. Realistic challenges include an unanticipated southerly gust front pushing air masses northward or model underestimation of insolation, though low-pressure dominance makes outliers like 13°C+ improbable without major synoptic shifts.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Warsaw Chopin Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/pl/warsaw/EPWA.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
