**Current forecasts from the Finnish Meteorological Institute (FMI) and ECMWF model runs position a daily maximum of 19–20 °C as the most probable outcome for Helsinki on August 18, 2026.** Late-August climatology supports this narrow range, with average highs near 19–20 °C as declining solar insolation and Baltic Sea thermal moderation limit extremes. Recent guidance shows stable high pressure, light southerly flow, and limited cloud cover, favoring modest warming above seasonal norms without strong warm advection that would push readings to 22 °C or higher. Ensemble spread remains tight, reflecting low uncertainty in boundary-layer mixing and sea-surface temperature feedbacks, which explains the market’s heavy concentration on 19–21 °C outcomes (combined >99 %). Lower-probability tails for 18 °C or below acknowledge minor risks from localized cooling or measurement-site variations, while negligible odds above 23 °C align with the absence of anomalous heat signals in the latest official data. Traders weight these forecasts heavily because resolution depends on verified observations, typically from Helsinki-Vantaa Airport, where model consensus has historically proved reliable this time of year.

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.
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.**Current forecasts from the Finnish Meteorological Institute (FMI) and ECMWF model runs position a daily maximum of 19–20 °C as the most probable outcome for Helsinki on August 18, 2026.** Late-August climatology supports this narrow range, with average highs near 19–20 °C as declining solar insolation and Baltic Sea thermal moderation limit extremes.
