Finnish Meteorological Institute observations at Helsinki-Vantaa Airport confirm the day's highest temperature reached 13°C earlier on April 20, 2026, under partly cloudy skies with light northerly winds (3-5 m/s) limiting further warming, aligning with forecast model consensus from ECMWF and GFS updated April 19 projecting a midday peak around 13°C. Evening readings now hover at 9-11°C with clear conditions and dropping solar insolation, solidifying trader consensus at near-certainty for this outcome per Wunderground resolution data. While inherent forecast uncertainty exists, a realistic challenge would require an anomalous late-afternoon heat burst exceeding models, improbable given current cooling trajectory and historical April norms of 10-12°C highs in Helsinki. Final observations expected within 24 hours.

This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 20 Apr '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Helsinki Vantaa Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized.
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.
