Trader consensus positions 23–24°C as the leading outcomes for Helsinki’s August 1 daily maximum, reflecting ensemble forecasts from the Finnish Meteorological Institute and ECMWF models that place the most likely range slightly above the early-August climatological average of 19–20°C. Persistent high pressure over the Baltic region, combined with southerly flow and relatively warm Gulf of Finland sea-surface temperatures near 18°C, supports modest daytime warming, while increasing cloud cover and light northerly winds later in the period limit further rises. Recent model runs show tight clustering around these values, with lower probabilities for 25°C+ or sub-22°C readings consistent with typical late-summer variability and forecast uncertainty ranges of ±1–2°C.
