Latest forecast guidance from sources including the Finnish Meteorological Institute and global models shows Helsinki under mostly cloudy conditions with light southwesterly winds and a chance of light showers, limiting daytime warming and pointing to a maximum near 16–17 °C. This keeps the 17 °C outcome narrowly ahead in trader pricing, while the close 18 °C probability reflects residual model spread on whether brief afternoon breaks in cloud cover could add an extra degree before any cooling. The historical September 10 average high of 16.4 °C provides context, yet current surface observations and ensemble runs indicate slightly above-normal potential without strong insolation. Final official readings from stations such as Helsinki-Vantaa will resolve the market once the calendar day ends.

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.
