Current model consensus from sources including the Finnish Meteorological Institute and ECMWF indicates overnight lows near 13°C for Helsinki on September 18 under persistent southwesterly flow, extensive cloud cover, and periods of rain totaling around 10 mm. These conditions advect milder maritime air while limiting radiative cooling and maintaining boundary-layer mixing via 5–10 m/s winds. Trader emphasis on 10–11°C outcomes reflects model spread in exact minimum timing and any brief clearing that could enhance nocturnal temperature drops by 1–2°C. Historical September averages near 9°C provide context, yet the active synoptic pattern favors milder readings. Updated short-range guidance and local observations will clarify resolution thresholds ahead of market close.

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 18 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 model consensus from sources including the Finnish Meteorological Institute and ECMWF indicates overnight lows near 13°C for Helsinki on September 18 under persistent southwesterly flow, extensive cloud cover, and periods of rain totaling around 10 mm.
