**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.**
