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 22 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 international models indicate a daytime maximum near 18–19°C in Helsinki on August 22, 2026, under overcast skies with light showers and southwesterly winds of 3–6 m/s that limit diurnal heating. Persistent cloud cover and modest Atlantic moisture advection have kept surface temperatures below seasonal norms, consistent with the observed late-August cooling trend (daily highs declining ~4°C month-over-month). Ensemble guidance shows low spread around these values, with only isolated runs reaching 20°C if breaks in cloud occur; sub-17°C outcomes remain unlikely absent rapid advection of colder air. This scientific consensus underpins the 55% market weighting on 19°C, with traders incorporating the latest model runs and real-time observations to refine implied probabilities ahead of final station readings.
