Korea Meteorological Administration (KMA) short-range forecasts and real-time observations confirm Seoul's highest temperature on March 30, 2026, peaked at 18°C amid mostly cloudy skies, light northerly winds, and scattered showers that capped solar heating. Midday readings hit 17–19°C per hourly updates, aligning with model ensembles showing persistent cloud cover limiting convective warming in a mild late-winter air mass—warmer than the March climatological average of 12–13°C but consistent with recent spring-like trends. Trader consensus at near-certainty reflects KMA data as the market's resolution authority. Realistic challenges include prolonged clearing before sunset enabling 1–2°C radiative surge, though low rain probabilities (20%) and evening cooldown make exceedance improbable; final daily observations expected shortly.
