Recent forecast model consensus from sources including the Finnish Meteorological Institute, GFS, and European ensembles points to a daily maximum of 16°C in Helsinki on September 21, driven by northerly flow advecting cooler maritime air behind a departing low-pressure system, combined with increasing high cloud cover that limits daytime heating. Observed highs on September 20 reached 15–16°C under similar conditions, consistent with late-summer climatology for the region. Light winds and scattered showers expected midday further moderate surface temperatures. Market-implied odds favoring 16°C reflect this tight clustering of guidance, with modest support for 17°C if clearing allows greater insolation. Official observations from Helsinki stations will resolve the market once the full diurnal cycle completes.

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.
