This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 12 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.Finnish Meteorological Institute's latest point forecast indicates a 9°C maximum around 15:00 on April 12 under dry, low-wind conditions with minimal cloud cover, yet trader consensus favors 11°C (38.5% implied probability) and 12°C (31%), reflecting ensemble spreads across GFS and ECMWF models showing potential for stronger diurnal heating up to 12-13°C. This tight race stems from April 11's observed 9°C high—above the mid-April climatological average of 8°C—amid a persistent high-pressure ridge delivering mild continental air and clear skies that enhance solar insolation. Key differentiators include subtle variations in afternoon cloudiness and exact peak heating timing, with 80% prediction intervals spanning 0-15°C; watch FMI updates overnight for refined guidance ahead of Helsinki-Vantaa Airport observations resolving the market.
