Forecast models from the Finnish Meteorological Institute and other agencies indicate a mild overnight minimum around 10–12°C for Helsinki on September 18, driven by persistent southwesterly flow, high humidity near 90%, and widespread cloud cover limiting radiational cooling. Recent runs show stable conditions with light rain or drizzle expected, which further moderates temperature drops compared to clearer historical analogs averaging near 9°C. Trader consensus clusters near 10–11°C because ensemble spreads remain modest, though small differences in wind speed or cloud timing could shift the exact low by 1–2°C. Updated short-range guidance and any late-model adjustments before midnight local time represent the key variables that could refine these market-implied probabilities.

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.
