Current forecasts from the Finnish Meteorological Institute and ECMWF models indicate the lowest temperature in Helsinki today will reach 3°C, driven by a stable high-pressure system and clear overnight conditions that promote radiative cooling under light winds. This aligns with climatological norms for mid-September in southern Finland, where minimums typically range 4–8°C. The overwhelming 99.4% market-implied probability reflects verified model consensus and recent observational trends showing no warmer air advection. A realistic challenge would require an unexpected warm front or measurement revision at the Helsinki-Vantaa station, though such shifts appear improbable given the short remaining observation window.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Helsinki Vantaa Airport Station in degrees Celsius on 12 Sep '26.
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.Current forecasts from the Finnish Meteorological Institute and ECMWF models indicate the lowest temperature in Helsinki today will reach 3°C, driven by a stable high-pressure system and clear overnight conditions that promote radiative cooling under light winds.
