Recent short-range forecasts from the Korea Meteorological Administration indicate daytime highs in Seoul near 28–29°C under mostly clear to partly cloudy skies with light winds, aligning with early summer climatology before peak monsoon humidity builds. Ensemble model consensus and recent observational trends support this range as the most probable outcome, with limited potential for brief warming to 30°C or cooling below 27°C depending on cloud cover and urban heat island effects. Trader-implied odds reflect high confidence in these authoritative guidance products, tempered by typical forecast uncertainty of 1–2°C on any given day.
