Recent forecasts from the Finnish Meteorological Institute, Foreca, and other models converge on a 16°C high for Helsinki on September 19 under persistent southwesterly flow, extensive cloud cover, and periods of rain that suppress daytime warming. This places the day slightly above the mid-September climatological average of roughly 14°C while remaining well below thresholds for stronger anomalies. Model agreement across runs through September 17 supports limited variability, with only modest upside risk if breaks in cloud cover allow brief additional heating. Market-implied odds heavily favor 16°C as the resolution outcome, reflecting trader alignment with this stable forecast consensus ahead of any final observational data.

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.
