This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Helsinki Vantaa Airport Station in degrees Celsius on 26 Aug '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=efhk To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market can not resolve until the first data point for the following date has been published on the resolution source. 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Recent official forecasts from the Finnish Meteorological Institute and models like Foreca and Yr.no indicate a high of 21–22°C in Helsinki on August 26 under partly cloudy skies, light northerly winds shifting southerly, and negligible precipitation. This consensus drives the near-even market split between 21°C and 22°C. At 60°N latitude in late summer, peak insolation occurs midday with limited diurnal range due to marine influence from the Baltic; subtle differences hinge on exact cloud cover during maximum heating, boundary-layer mixing, or minor advection of warmer air masses. Stable high-pressure conditions minimize uncertainty, though updated afternoon model runs could refine the peak by a degree before resolution.
