This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 7 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.Forecast models from the Finnish Meteorological Institute and other sources indicate a typical early-August pattern over southern Finland, with a moderating southwesterly flow, partly cloudy skies, and light showers possible on August 7 that limit daytime heating. This setup supports a maximum near the long-term Helsinki average of 20–21 °C, explaining why those outcomes dominate market-implied odds at 54 % and 28.5 %. Recent runs show little model spread, with no signs of stronger high pressure or southerly advection that would push readings to 23 °C or above. Official guidance highlights modest wind speeds and dew points that cap the thermal peak, consistent with the low probabilities assigned to cooler or warmer extremes. Updated forecasts ahead of the daily maximum will be the key near-term catalyst for any shifts in trader positioning.
