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. 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 forecasts from the Finnish Meteorological Institute and converging models from AccuWeather and the UK Met Office indicate a daytime maximum of 20–21 °C in Helsinki on August 14 under overcast skies and light southerly flow. These conditions limit solar heating and warm-air advection typical of late-summer Baltic patterns, anchoring trader consensus on the 21 °C outcome at 72.5 % implied probability. Historical August highs average near 19–20 °C, with only modest upside risk under clearer anticyclonic setups; current guidance shows low deviation potential for 22 °C or higher. Updated model runs and persistent cloud cover have further tightened the distribution around the leading bin while keeping lower outcomes at minimal odds.
