Recent forecast models from the Finnish Meteorological Institute and international ensembles indicate a cooling trend after a warmer August 10, with daytime maxima for Helsinki on August 12 settling near 18–19°C under cloudy skies, light winds, and minimal precipitation risk. This aligns with climatological August averages of 19–20°C while reflecting a northerly air mass shift that suppresses peak heating. Traders have concentrated implied probability on 19°C (49%) and 20°C (25.5%), consistent with ensemble consensus and limited upside from brief afternoon clearing. Updated model runs expected within the next 24–48 hours could refine these probabilities ahead of the August 12 resolution window.

This market will resolve based on the highest 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 highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 12 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest 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.
