This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 13 Jun '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.Current short-range model consensus from agencies including the Finnish Meteorological Institute and ECMWF indicates a highest temperature in Helsinki on June 13 most likely between 15–18°C, with light southerly flow, possible drizzle, and limited daytime heating under variable cloud cover. This distribution drives the market's heaviest weighting toward 18°C (34%) and 17°C (23.5%), while the tail probabilities for 19–22°C reflect occasional warmer ensemble members or slight model spread in boundary-layer warming. Key variables include the exact timing of any weak frontal passage, wind direction shifts that could enhance or suppress mixing, and the degree of insolation under broken stratiform clouds—factors that can still shift by 1–2°C with updated runs before resolution. Historical June averages near 16–17°C provide context, yet the narrow two-day lead time keeps uncertainty elevated until final observations confirm the daily maximum.
