This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 6 Apr '26. 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 Helsinki Vantaa Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/fi/vantaa/EFHK. 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.Trader consensus on Polymarket reflects profound uncertainty in Helsinki's highest temperature on April 6, with all outcomes from 0°C or below to 10°C or higher trading at equal 25.5% implied probabilities, as forecast ensembles from the Finnish Meteorological Institute (FMI) show an 80% prediction interval spanning -5°C to 15°C three days out. This stems from early April's transitional weather patterns over the Baltic Sea region, where northerly continental polar air masses could suppress maxima near 0-3°C, while westerly maritime flows enable 6-9°C peaks amid variable cloud cover and light precipitation risks. The FMI's latest run (updated April 2 evening) centers on a 5°C high—aligning with the 5.9°C climatological average—but model divergences in low-pressure positioning and wind shear create the wide spread. Watch daily FMI updates and ECMWF/GFS ensembles for shifts ahead of resolution based on official Helsinki observations.
