Korea Meteorological Administration's (KMA) latest short-range forecast projects Seoul's highest temperature on May 1 at 22-23°C amid mostly cloudy morning skies clearing to partly sunny afternoons, with just 10% precipitation probability and light winds. This drives trader consensus toward 20°C or higher at 47% implied probability, tempered by ensemble model spreads in ECMWF and GFS outputs plus recent spring rains that cooled the region after mid-April's record highs exceeding 29°C. Early May climatology averages around 20°C highs during this transitional spring period, when high-pressure ridges promote mild warmth but variable cloud cover and urban heat island effects introduce uncertainty. KMA hourly updates and official station measurements will refine outcomes as the day progresses.
