**Consensus forecasts from the Finnish Meteorological Institute and supporting models indicate a daytime maximum of 19–20 °C for Helsinki on August 29, driven by mild southerly flow under mostly cloudy skies with limited diurnal heating from the Baltic Sea.** This places the highest temperature squarely in the market's leading outcomes (20 °C at 59.5 % implied probability, followed by 21 °C at 24 % and 19 °C at 14 %), consistent with near-normal late-August climatology where average highs hover around 18–19 °C. Ensemble guidance shows little spread for extremes, as stable pressure patterns and moderate winds (roughly 5–10 m/s) suppress both stronger warming and sharp cooling. No significant model updates or synoptic shifts have emerged in the past 24–48 hours to alter this range, keeping probabilities anchored to the narrow forecast cluster rather than outlier scenarios.
