Current forecasts from the Korea Meteorological Administration and global models indicate potential for daytime highs in Seoul on June 11 near the 22–24°C range due to variable cloud cover, scattered showers, and moderating northerly flow ahead of the approaching monsoon. These conditions create narrow uncertainty in peak solar heating and boundary-layer mixing, with slight differences in timing of any rain or afternoon clearing tipping the exact maximum between the leading outcomes. Historical early-June averages hover around 25–27°C, but recent model runs emphasize cooler-than-climatological guidance from persistent marine influence and limited insolation. Traders’ tight clustering reflects this short-term forecast sensitivity, with final KMA station observations expected to resolve the market by evening.
