Recent short-term forecasts from the Finnish Meteorological Institute and European Centre for Medium-Range Weather Forecasts show Helsinki’s May 18 daytime maximum most likely reaching 19–22 °C under a mild southwesterly flow and partly cloudy skies. Ensemble spreads remain wide because small shifts in cloud timing or wind speed can swing the peak by 2–3 °C, keeping the three leading outcomes nearly equal. Historical May maxima in the city average 16 °C, so current model guidance already reflects above-normal warmth for mid-month. Updated runs expected later today and tomorrow will likely narrow the distribution and shift probabilities ahead of the market’s close.
