Recent numerical weather prediction models from sources including the Finnish Meteorological Institute and ECMWF ensembles indicate a maximum temperature in Helsinki most likely reaching 16–17°C on September 17, driven by southwesterly flow and partial cloud cover following overnight rain on the 16th. These conditions support modest daytime warming without strong advection of warmer air masses, keeping the probability of 18°C or higher low while limiting downside risk below 15°C. Historical climatology places the September 17 average high near 15°C, but current model consensus has shifted trader-implied odds toward the upper end of the near-term range. Updated forecast runs and surface observations through the day will refine the final recorded maximum before market 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.
