Official measurements from the Finnish Meteorological Institute confirmed a daily maximum of 19°C in Helsinki on August 13, driving the market's 100% consensus on this outcome. This aligns with regional forecasts showing modest highs under mostly cloudy conditions and a northwesterly flow that limited daytime warming, consistent with late-summer climatology where averages hover near 18–20°C. Traders placed full weight on verified station data rather than models, given the day's proximity to resolution. Revisions to official records or discrepancies among Helsinki-area stations remain the only realistic paths to an alternative outcome, though such adjustments are rare once preliminary observations are validated.
