Recent forecast model consensus from the Finnish Meteorological Institute and Met Office indicates a daily maximum of 20–21°C in Helsinki on August 14 under partly cloudy skies and light northwesterly flow, anchoring the market’s heaviest trading around those bins. Baltic Sea surface temperatures near 18°C provide modest moderation that limits strong daytime heating, while variable cloud cover and the timing of a weak trough introduce enough uncertainty to sustain 22°C as a viable secondary outcome. This aligns with typical mid-August climatology, where highs average near 19–20°C and exceed 23°C infrequently. Traders are monitoring the next model runs and observational updates for any shifts in cloud or wind patterns that could adjust the peak by 1–2°C.

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 14 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.
