Recent ensemble forecasts from European and global models position daily maximum temperatures in Helsinki on August 1 in the 20–24 °C range, with the 23 °C outcome leading trader consensus due to the latest runs favoring a brief warm advection ahead of an approaching Atlantic trough. Climatologically, early-August highs average near 19–20 °C at the Finnish Meteorological Institute station, so current probabilities reflect modest positive anomalies tied to reduced cloud cover and lighter northerly flow rather than extreme heat. Model spread remains notable, with some solutions keeping highs near 21 °C under increasing maritime influence and showers, explaining why adjacent bins at 21 °C and 24 °C also hold substantial implied probability. Updated high-resolution guidance expected within 24 hours will likely tighten the distribution before market resolution.

This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 1 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.Recent ensemble forecasts from European and global models position daily maximum temperatures in Helsinki on August 1 in the 20–24 °C range, with the 23 °C outcome leading trader consensus due to the latest runs favoring a brief warm advection ahead of an approaching Atlantic trough.
