Recent forecast updates from the Korea Meteorological Administration indicate a daytime maximum of 25°C in Seoul on May 17, driven by stable high-pressure conditions and moderate southerly flow that limit both heating and cooling extremes. This consensus aligns with ensemble model runs showing limited variability in surface temperatures, placing the outcome well within the typical mid-May climatological range of 23–27°C for the region. While the market-implied odds reflect strong trader agreement backed by real capital, a sudden increase in cloud cover, stronger northerly winds, or delayed onset of daytime heating could shift the observed high by 1–2°C and alter the resolution. Updated KMA briefings and real-time observations through the afternoon remain the key data points for any final adjustments.
