Forecast models from sources including the Finnish Meteorological Institute and ECMWF show mostly clear skies and light northwesterly winds over Helsinki on September 6, promoting strong nocturnal radiative cooling under a building high-pressure ridge. This setup favors minimum temperatures clustering in the 6–8°C range, below the 10.8°C climatological average, with limited cloud cover and dew points near 7–9°C limiting further drops. Ensemble spreads reflect minor differences in boundary-layer mixing and exact wind speeds, keeping outcomes from 5°C to 9°C tightly bunched in market pricing. Updated runs overnight will clarify whether calm conditions allow readings near 6°C or if slight advection keeps them closer to 8°C.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
