Recent forecast guidance from the Finnish Meteorological Institute and ensemble models indicates a daily maximum near 16–17 °C for Helsinki on September 19, supported by mild southwesterly flow and limited daytime heating under cloudy, showery conditions. This places the outcome slightly above the long-term September 19 average of roughly 14.7 °C while remaining within the typical interannual range. Persistent Atlantic low pressure and associated frontal systems have kept temperatures close to seasonal norms in recent days, with minimal model spread on peak values. Traders are weighting the 16 °C and 17 °C bins most heavily because further warming would require stronger ridging or clearer skies that current runs do not support, while cooler outcomes would need an unexpected cold-air intrusion unlikely before resolution. Updated model cycles through the weekend will refine these probabilities.

The resolution source for this market will be information from NOAA, specifically the highest 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.
