Current forecast models from the Finnish Meteorological Institute, Foreca, and Yr.no indicate an overnight low near 15°C for Helsinki on August 30, driven by persistent cloud cover, 60-75% rain probability, and southerly winds advecting mild, moist air that limits radiative cooling. This aligns with the market's leading 15°C outcome at 53.5% implied probability, while 14°C (26%) remains viable if clearer intervals develop overnight. Historical August 30 averages show a 11.9°C low, but 2026 conditions are running warmer amid the current pattern; traders appear to weight the latest model consensus heavily, with lower probabilities on extremes reflecting limited downside risk from the stable setup. Updated guidance from monitoring agencies could refine these odds ahead of resolution.

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 30 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 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.
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.Current forecast models from the Finnish Meteorological Institute, Foreca, and Yr.no indicate an overnight low near 15°C for Helsinki on August 30, driven by persistent cloud cover, 60-75% rain probability, and southerly winds advecting mild, moist air that limits radiative cooling.
