Current forecasts from agencies like the Finnish Meteorological Institute and European models point to a daily high of 15–16 °C in Helsinki on September 6, supported by northwesterly flow, partly cloudy skies, and surface observations already tracking near 14–15 °C midday. This aligns with the late-summer cooling trend, where average highs decline from 18 °C early in the month toward 15 °C by mid-September, and recent model runs show limited diurnal warming under moderate winds. Trader consensus on 15 °C (59 %) and 16 °C (32.5 %) reflects the narrow range of official station readings expected before sunset, with resolution hinging on the highest verified hourly or daily maximum at the primary Helsinki observation site.

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.
