Forecast models from sources like the Finnish Meteorological Institute and GFS indicate Helsinki's overnight minimum on September 13 will likely fall between 9–13 °C, with 11–12 °C favored due to persistent cloud cover, light southwesterly winds, and limited radiative cooling under a mild maritime air mass. These conditions suppress the typical nocturnal drop seen in clearer autumn nights, aligning with the market's tight clustering around those outcomes. Historical averages place the September 13 low near 9.7 °C, but recent warmer patterns and model consensus on minimal clearing keep probabilities balanced. Updated runs tonight and early-morning observations will refine exact thresholds, as small shifts in timing or cloud breaks could push the recorded minimum toward 10 °C or 13 °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.
