**Official observational data from the Finnish Meteorological Institute (FMI) confirms Helsinki's highest temperature on April 21, 2026, peaked at 15°C, driving the market's 100% implied probability on this outcome as traders align with verified measurements from key stations like Helsinki-Vantaa Airport.** This reading aligns with FMI's latest hourly observations updated late on April 21, capturing peak daytime warmth under partly cloudy skies and mild southerly airflow following cooler prior days. Above the April climatological average high of around 8–10°C, it reflects a brief warm spell amid typical spring variability. Scenarios challenging this include rare post hoc data corrections or disputes over station selection, though FMI's authoritative records render such shifts highly improbable, with market resolution imminent.**

This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 21 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.
