Finnish Meteorological Institute forecasts and ECMWF ensembles currently indicate a daytime maximum near 24°C at Helsinki-Vantaa on July 12, with a heat-wave warning in place but limited upside potential under modest southerly flow and possible afternoon cloud cover. Trader probabilities remain tightly clustered between 26–29°C because ensemble spread at 48–72-hour lead times allows for modest warming if skies clear or winds weaken, while marine influence from the Baltic caps extremes. Historical July climatology places average highs in the low-to-mid 20s, so outcomes hinge on the precise timing of any ridge axis and diurnal heating rates. Updated model runs and FMI briefings over the next 24 hours will likely narrow the distribution ahead of market resolution.
