Recent forecast model consensus from the Finnish Meteorological Institute and ECMWF points to a daytime high of 17°C in Helsinki on September 11, driven by northwesterly winds of 6–7 m/s, partly cloudy skies, and limited moisture that should cap warming near the seasonal average of 16.2°C. Multiple runs show peak readings between 16–18°C depending on exact cloud cover and wind shifts, explaining why traders assign over 87% combined implied probability to those two outcomes. Cooler anomalies earlier in the week have kept longer-range guidance from pushing higher, while the absence of strong southerly flow or clear skies reduces odds of reaching 19°C or above to just 2.5%. Updated model outputs tomorrow morning will refine the exact maximum before resolution.

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.
