**Trader consensus has converged on 16°C as the implied probability for Helsinki’s daily maximum temperature on September 16, reflecting consistent official forecasts and observations.** The Finnish Meteorological Institute reports afternoon peaks reaching 16°C under overcast skies with light rain, aligning with ensemble model guidance and climatological norms for mid-September in southern Finland. This outcome is supported by real-time surface observations and steering patterns that limit further warming. Scenarios that could alter resolution include localized station readings exceeding model consensus due to brief clearing or post-event data revisions by monitoring agencies, though current evidence indicates low likelihood of deviation.

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.
