Recent forecast runs from the Finnish Meteorological Institute and ECMWF show Helsinki’s September 15 minimum temperature most likely falling between 9 °C and 13 °C under light southerly flow and building high pressure that limits overnight radiative cooling. Model consensus places the daily low near or slightly above the 9.4 °C climatological norm, yet modest spread in boundary-layer moisture and wind direction keeps the 2 °C-or-below and 12 °C-or-higher outcomes nearly even at roughly 49 % each. A strengthening Atlantic trough arriving after the 16th introduces the main uncertainty, with any earlier timing shift or stronger northerly component able to push the minimum several degrees lower. Fresh model cycles expected within 24 hours will narrow the range and clarify whether the market’s tight split reflects genuine forecast dispersion or lingering position adjustments.

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.
