Current ensemble forecasts from European meteorological models point to a daytime maximum in Helsinki on August 20 near 18–20°C, reflecting typical late-summer Baltic conditions with moderate southwesterly flow and variable cloud cover that limits strong diurnal warming. Official data from the Finnish Meteorological Institute and historical August averages near 19°C anchor trader expectations, while model spread in timing of any showers or wind shifts creates the tight clustering around 19°C (32% implied probability) versus 20°C (24.5%). Updated short-range runs and observational adjustments before resolution will refine these probabilities, as small differences in boundary-layer moisture or insolation can shift the recorded 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 20 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.
