**Recent forecast models from sources like the Finnish Meteorological Institute and ECMWF indicate overnight lows in Helsinki near 11–13°C for August 21, 2026, positioning 11°C as the market leader at 59.5% implied probability.** This reflects typical late-August cooling in southern Finland, where average lows decline toward 9–13°C amid shorter days and reduced solar heating. Clear or partly cloudy conditions overnight promote radiative cooling without strong warm advection, while light winds limit mixing that could raise minimums. Supporting outcomes at 10°C (25.5%) and nearby values (8–9°C) capture model spread and local urban heat island effects around the measurement site. Warmer or much colder extremes remain low-probability given the stable pattern and absence of unusual air masses. Updated model runs and official observations through the night will refine these trader-assessed odds.

This market will resolve based on the lowest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the lowest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the Helsinki Vantaa Airport Station, available here: https://www.wunderground.com/history/daily/fi/vantaa/EFHK.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.**Recent forecast models from sources like the Finnish Meteorological Institute and ECMWF indicate overnight lows in Helsinki near 11–13°C for August 21, 2026, positioning 11°C as the market leader at 59.5% implied probability.**
