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 8 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 that 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 will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first. 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 forecasts from the Finnish Meteorological Institute, Foreca, and Yr.no converge on a maximum of 17–18°C for Helsinki on September 8, aligning with the market’s leading implied probabilities. This reflects typical early-September conditions, where the long-term average high is 16.7°C at Kaisaniemi, modulated by southerly flow that can briefly elevate temperatures before increased cloud cover and light precipitation limit afternoon warming. Model consensus shows limited spread around these values, with only modest upside potential if clearer skies develop. Traders are pricing the narrow range heavily because resolution hinges on the official daily maximum recorded at the reference station, and updated runs in the next 24 hours are unlikely to shift the outlook dramatically.
