Forecast models from agencies like the Finnish Meteorological Institute and ECMWF indicate a southeasterly flow bringing mild maritime air and increasing cloud cover to Helsinki by August 29, supporting overnight lows near 14–16 °C with modest rain chances. Clear-sky radiative cooling is reduced under the cloud deck while stronger winds enhance mixing, limiting surface temperature drops. Ensemble spreads and model-to-model differences in frontal timing create the tight clustering around 13–15 °C outcomes, with the 33 % probability on 10 °C or below reflecting residual tail risk if cooler continental air arrives earlier than currently projected. Updated runs ahead of the 29th landfall window will refine these thresholds.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Helsinki Vantaa Airport Station in degrees Celsius on 29 Aug '26.
The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=efhk
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.Forecast models from agencies like the Finnish Meteorological Institute and ECMWF indicate a southeasterly flow bringing mild maritime air and increasing cloud cover to Helsinki by August 29, supporting overnight lows near 14–16 °C with modest rain chances.
