Current forecast consensus from numerical weather prediction models, including runs from the Finnish Meteorological Institute and ECMWF, positions a daily maximum near 20°C in Helsinki on August 18, 2026, under stable high pressure, light southerly flow, and limited cloud cover. This aligns with late-August climatology, where average highs typically fall to 19–20°C amid declining solar insolation and moderating Baltic Sea influence. Recent guidance shows no strong warm advection or radiative cooling signals that would push extremes beyond the narrow 19–21°C envelope, supporting the market’s heavy weighting toward 20°C (54.5%) while assigning lower probabilities to 19°C or 21°C outcomes due to residual uncertainty in boundary-layer mixing. Official observations and updated model ensembles expected later today will refine resolution criteria.

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 18 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.
