This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 16 May '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.Current ensemble forecasts from the Finnish Meteorological Institute and ECMWF project a daytime maximum near 18°C in Helsinki on May 16, driven by mild southerly advection of warmer Atlantic air under a high-pressure ridge and moderate solar insolation amid partly cloudy skies. This positions the 18°C outcome as the clear market leader at 88.5% implied probability, with 19°C trailing at 8.1%, reflecting modest uncertainty in peak timing and cloud cover. Recent observational data through midday confirm readings tracking within the narrow 16–18°C band, consistent with May climatology of 14–15°C but elevated by the synoptic pattern. Hourly FMI updates and boundary-layer mixing details will clarify final resolution as insolation wanes.
