Recent official forecasts from the Finnish Meteorological Institute and ensemble models indicate a daytime high near 19–20°C for Helsinki on August 21, aligning closely with the market’s leading outcomes at 34.5% and 32.0% implied probability. Late-summer cooling under northwesterly flow, combined with increasing cloud cover and light showers, is limiting daytime solar heating and keeping maxima near or slightly below seasonal averages. Key differentiating factors include the precise degree of cloudiness, boundary-layer moisture, and any short-wave trough timing that could enhance or suppress warming by 1–2°C. Forecasters note typical model spread at this range, with updates from NHC-style regional guidance and local observations expected to refine the outlook ahead of resolution.

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 21 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.
