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 28 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 If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source. 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 forecasts from the Finnish Meteorological Institute and consensus models show a daytime high near 19°C for Helsinki on August 28 under mostly cloudy skies, light southeast winds around 4–8 m/s, and minimal solar heating. This positions 20°C (45.5% implied probability) and 21°C (25%) as frontrunners, reflecting typical late-summer variability and slight upward model spreads rather than strong warming. Lower outcomes like 19°C (20%) remain viable if cloud cover thickens or winds strengthen, while extremes below 18°C or above 22°C carry low probabilities given stable high pressure and absence of significant fronts. Traders weigh these official guidance updates against historical August baselines around 20–22°C.
