Recent forecast model runs for Helsinki show minimum temperatures on August 23 clustered near 11–12 °C, with official guidance from the Finnish Meteorological Institute and European ensembles indicating a mix of cloud cover, light rain, and moderate northwesterly winds that limit nocturnal radiative cooling. This keeps the market closely divided between the 9 °C-or-below outcome (45.5 %) and the 14 °C outcome (44.5 %), as small shifts in cloud timing or wind speed can swing the overnight low by 2–3 °C. Historical August climatology places typical lows near 10–12 °C, so current consensus reflects a modest cool anomaly without extreme blocking patterns. Traders are watching the next 48-hour model updates for clearer signals on boundary-layer moisture and high-pressure influence.
