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 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 short-range forecasts from the Finnish Meteorological Institute and ECMWF ensemble runs indicate a daytime peak near 17–18°C in Helsinki on July 7, driven by persistent maritime air from the Baltic Sea, moderate cloud cover limiting solar heating, and light southwesterly flow. These conditions align with typical early-July variability at this latitude, where Gulf of Finland sea-surface temperatures moderate extremes and suppress strong diurnal warming. The closely matched market odds around 16–18°C reflect genuine forecast uncertainty from minor model spread on timing of any showers, with historical July highs averaging near 21°C providing context for the cooler current pattern. Traders will watch the next FMI update and ensemble guidance for shifts in cloud or wind regimes before resolution.
