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 1 Sep '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 If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event which there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket. 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.
Latest forecasts from sources including the Finnish Meteorological Institute, Yr.no, and WeatherBug converge on a daily maximum of 19–20 °C for Helsinki on 1 September 2026, driven by southwesterly flow under partly cloudy conditions with minimal precipitation. This aligns closely with the 1991–2020 climatological average high of 18.0 °C for the date and recent model runs showing limited diurnal warming. The market’s concentration on 19 °C (23 %), 20 °C (57 %), and 21 °C (21 %) therefore reflects the narrow uncertainty band around these consensus values, with lower-probability tails corresponding to deviations that would require unexpected shifts in cloud cover or advection. Official station data from Helsinki-Vantaa or Kaisaniemi will determine resolution once the 24-hour maximum is recorded.
