This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 15 Jul '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 official forecasts from the Finnish Meteorological Institute and European models project a daily maximum around 24–25°C for Helsinki on July 15, 2026, under mostly cloudy skies with light northeasterly flow and limited solar heating. Historical July climatology shows average highs near 21–22°C, with occasional peaks to 26–28°C when subtropical ridges strengthen over Scandinavia and suppress marine influence from the Baltic. Trader positioning at 26–28°C likely incorporates model spread and the chance of clearer conditions or warmer advection in the final 48 hours, while lower outcomes reflect the current consensus trajectory and typical late-summer cooling. Updated model runs and surface observations through July 14 will refine these probabilities ahead of market resolution.
