About this Market

Forecast model consensus from sources including the Korea Meteorological Administration and global ensembles points to a mostly clear to partly cloudy day on September 29 with light variable winds and minimal precipitation, supporting market-implied odds favoring a daily maximum of 23–24°C in the Seoul-Incheon area. These outcomes reflect tight clustering around recent GFS and ECMWF runs showing afternoon highs near 24–26°C (75–79°F), with trader positioning sensitive to small differences in daytime heating driven by cloud cover, boundary-layer mixing, and wind direction shifts that can alter peak temperatures by 1–2°C. Late-September climatology for Incheon averages highs around 24–25°C, providing context for the narrow spread between leading probabilities. With resolution imminent, fresh model updates and official briefings over the next 48 hours represent the key variables that could shift sentiment toward 25°C or pull it lower.
