Official forecasts from the Finnish Meteorological Institute indicate a daytime maximum of 20°C in Helsinki on August 8 under moderate southwesterly flow, partly cloudy skies, and minimal precipitation that limits solar heating. This aligns with late-summer climatology, where average highs typically reach 19–20°C, and recent observations on August 7 showing comparable values with no strong warm advection or clear-sky amplification. Market-implied odds reflect strong trader consensus on these conditions, as real-capital positions aggregate the latest model guidance and official data. A shift to sustained clear skies or enhanced southerly flow could push readings higher, while increased cloud cover or showers might cap the peak below the threshold.

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 8 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.
