Recent forecasts from multiple models show Helsinki's September 24 minimum temperature likely falling between 9–11°C amid northerly flow, extensive cloud cover, and periods of light rain that limit nocturnal radiative cooling. The near-even market split between sub-5°C and 15°C+ outcomes reflects lingering uncertainty in the precise timing and intensity of an incoming frontal system, which could either enhance cooling through evaporation or moderate lows via persistent cloud and mixing. Historical September minima in the region average near 8–10°C, providing context for why traders see narrow differentiation among mid-range outcomes. Updated ECMWF and GFS runs expected in the next 24 hours will likely clarify steering patterns and precipitation timing.

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 24 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.Recent forecasts from multiple models show Helsinki's September 24 minimum temperature likely falling between 9–11°C amid northerly flow, extensive cloud cover, and periods of light rain that limit nocturnal radiative cooling.
