Latest ensemble forecasts from the Finnish Meteorological Institute and ECMWF place Helsinki-Vantaa’s May 17 daytime maximum in the narrow 16–17 °C band, reflecting light southerly advection of mild continental air under a weakening high-pressure ridge. Subtle model disagreements on afternoon cloud timing and boundary-layer mixing create the tight clustering between these two outcomes, while historical mid-May climatology averages 15 °C highs with occasional +2 °C anomalies during spring warming episodes. Resolution hinges on official 24-hour maximum readings once insolation peaks and any thin high cloud or brief frontal influence materializes; traders therefore track the next FMI hourly update for any revision in peak heating potential.
