Recent Finnish Meteorological Institute forecasts project Helsinki's highest temperature at Vantaa Airport on April 14 at 12°C under clear skies, light 3 m/s winds from the north, and minimal precipitation risk below 10%, reflecting a cool continental air mass over southern Finland. Yet trader consensus clusters around 13–14°C at 65% combined implied probability, driven by ensemble spreads in ECMWF and GFS models indicating potential for 1–3°C warmer peaks from enhanced solar insolation during 14+ hours of daylight and possible high-pressure ridging. The 21.5% odds on 15°C+ capture upside from model outliers with reduced mixing or thinner clouds, while sub-13°C outcomes lag amid above-climatological (~8°C mid-April average) expectations; new overnight runs from FMI and global models could sharpen resolution ahead of observations.

This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 14 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.
