Recent forecasts from models including ECMWF and GFS indicate clear skies and northerly flow over Helsinki on September 22, supporting radiative cooling overnight that favors minimum temperatures near 8–9°C. Trader sentiment reflects tight clustering around 6–8°C because small variations in wind speed, boundary-layer mixing, and exact timing of any residual cloud cover can shift the overnight low by 1–2°C. Historical climatology places the September 22 average minimum near 7–8°C, providing context for the balanced probabilities across outcomes from 4°C to 9°C. Updated model runs and local observations through the night will determine the final recorded low, with resolution hinging on official Finnish Meteorological Institute data.

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.
