Trader consensus on Polymarket reflects tight uncertainty in forecast models for Warsaw's highest temperature on April 12, with 14°C (35.5%) narrowly leading 13°C (30.5%) and 15°C or higher (24.5%), driven by the latest Institute of Meteorology and Water Management (IMGW) synoptic outlook projecting a maximum of 12°C under weak northerly winds and partly cloudy skies. However, ECMWF and GFS ensemble runs show a spread up to 15°C if a high-pressure ridge strengthens, allowing more solar heating amid recent cool nights with near-freezing lows and a cooling trend following early April highs near 21°C. Key differentiators include cloud cover variability and afternoon insolation rates, with new 12Z model updates expected later today to potentially sharpen probabilities ahead of resolution based on official IMGW observations at Warsaw Chopin Airport.

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.
