This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 4 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 for Helsinki's highest temperature on April 4, with market-implied probabilities evenly split at 25.5% across outcomes from 0°C or below to 9°C, and just 1.5% for 10°C or higher. The Finnish Meteorological Institute's latest forecast points to a daytime high near 3°C amid a cooling trend from recent 6-7°C readings, driven by westerly winds shifting northerly, increased cloud cover, and 50% precipitation odds that could suppress peaks. Prediction intervals (50-80%) span 0-6°C, capturing springtime variability from Baltic Sea moderation and passing fronts; ECMWF and GFS ensembles show similar spreads due to unresolved frontal timing. Historical early-April highs average 5°C with a 2-3°C standard deviation, underscoring potential for outliers, though 10°C+ remains climatologically rare. Hourly FMI updates will sharpen resolution tomorrow.
