**Forecast consensus from official sources like the Finnish Meteorological Institute (Ilmatieteen laitos), ECMWF, and Yr.no centers the highest temperature in Helsinki on August 24 around 19°C, with some runs near 18°C.** This reflects a stable late-summer pattern featuring mostly cloudy skies, light northwesterly winds around 5–6 m/s, and minimal daytime heating under a cool maritime air mass. Current conditions on August 23 show temperatures in the mid-15°C range with showers and northerly flow, which is expected to persist into Monday without significant warming. Historical data place the long-term average high for the date at 19.3°C, so the market-implied odds—led by 19°C (46%) and 18°C (34.5%)—align closely with model agreement and the absence of any anomalous ridging or southerly advection that could push readings higher. Traders appear to be pricing in limited upside risk from the cloudy, breezy setup while assigning low probability to 20°C+ outcomes or cooler extremes below 17°C. Updated model runs and the official FMI forecast on August 24 morning will provide the final resolution inputs.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Helsinki Vantaa Airport Station in degrees Celsius on 24 Aug '26.
The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=efhk
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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.**Forecast consensus from official sources like the Finnish Meteorological Institute (Ilmatieteen laitos), ECMWF, and Yr.no centers the highest temperature in Helsinki on August 24 around 19°C, with some runs near 18°C.** This reflects a stable late-summer pattern featuring mostly cloudy skies, light northwesterly winds around 5–6 m/s, and minimal daytime heating under a cool maritime air mass.
