Recent numerical weather prediction models, including runs from the Finnish Meteorological Institute and global ensembles, indicate a highest temperature in Helsinki on September 21 most likely near 15–16 °C under mostly cloudy skies with isolated showers and light northerly winds. This consensus, slightly above the long-term climatological average of about 14 °C for the date, underpins the market’s strong preference for 16 °C as the leading outcome. Minor model spread allows limited probability for 15 °C or 17 °C if afternoon clearing or residual moisture alters the peak, while updated guidance expected overnight will refine the exact maximum ahead of the 24-hour observation window.

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.
