Korea Meteorological Administration observations confirm Seoul's morning low temperature reached exactly 12°C around 0600 KST on May 14, aligning with short-range forecast model consensus from prior 24 hours that pinned the daily minimum there amid clear skies and light easterly winds. Daytime highs have climbed to 26°C with increasing solar heating, eliminating further cooling potential and driving trader consensus to 100% implied probability for 12°C versus negligible odds for 11°C or below. This positioning reflects May climatological norms, where Seoul lows average 12–16°C, supported by stable high-pressure systems. Realistic challenges include an anomalous late-day temperature plunge or official data revision from the primary station, though current synoptic patterns make these highly improbable; final KMA daily summary expected post-midnight.
