Traders have converged on a 100% implied probability for a 17°C high in Helsinki on August 12, 2026, reflecting real-time observational data from the Finnish Meteorological Institute showing the temperature peaked at that exact threshold amid moderate northwesterly winds, partial cloud cover, and limited daytime insolation typical of late-summer conditions. This positioning aligns with current surface measurements and short-range model consensus indicating stable, cool maritime air advection that suppressed further warming near the monthly average. Scenarios that could realistically shift the outcome include a sudden clearing of clouds allowing additional solar heating, a shift in wind direction introducing warmer continental air, or post-hoc adjustments in official station readings, though these remain low-probability given the advanced stage of the diurnal cycle.

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 12 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.Traders have converged on a 100% implied probability for a 17°C high in Helsinki on August 12, 2026, reflecting real-time observational data from the Finnish Meteorological Institute showing the temperature peaked at that exact threshold amid moderate northwesterly winds, partial cloud cover, and limited daytime insolation typical of late-summer conditions.
