**Persistent cool northeasterly flow and widespread cloud cover have capped Helsinki's maximum temperature near 6°C on October 12.** Official Finnish Meteorological Institute observations and multiple forecast models show daytime readings holding at 6–7°C amid light rain and overcast skies, well below the 1991–2020 average high of 9.9°C. This stable air mass, with dew points near 5°C and sustained winds, has prevented any significant diurnal rise, aligning with trader consensus reflected in the 95.5% implied probability for 6°C. Final resolution depends on the official daily maximum from the primary Helsinki station; minor upward revisions to 7°C remain possible if a brief late-day spike occurs, though current data streams make that unlikely.
