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 25 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.
Recent weather model consensus from the Finnish Meteorological Institute, Foreca, and Yr.no indicates a likely daily maximum of 19–21°C in Helsinki on August 25, 2026, under northerly flow and partly cloudy skies with negligible precipitation risk. Historical August averages for the date sit near 19°C, and current late-summer conditions show a modest cooling trend after recent days with highs of 19–21°C. Ensemble guidance highlights light to moderate northwest winds limiting daytime warming, while clear to scattered cloud cover supports temperatures peaking in the late afternoon. This scientific setup—stable high pressure, seasonal decline in solar insolation, and consistent model runs—explains why traders have concentrated implied probability on 19°C (49.5%) and 20°C (32.0%), with lower odds on 18°C or 21°C reflecting minor forecast spread and measurement variability at the official station. Upcoming model updates overnight will refine the exact peak.
