Traders see the Helsinki minimum temperature on September 21 clustering tightly around 8–10 °C because official forecasts and model consensus place the overnight low in that narrow band under partly cloudy skies, light northerly winds, and isolated showers. Recent surface observations show temperatures holding near 12–13 °C through the early morning with dew points around 9–11 °C, while ensemble guidance indicates modest cooling potential if clear spells develop but limited further drop if clouds persist. This range aligns with slightly above-normal September conditions for the region, where historical minima average near 8 °C; any shift in the final model runs or local wind patterns could still tip the recorded low between the leading outcomes before official verification.

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.
