**Forecast models from the Korea Meteorological Administration and international ensembles currently favor a daytime high of 26–28°C in Seoul on June 22, 2026, aligning with the market’s top outcomes at 27°C (38.5%) and 26°C (26.0%).** Near-normal early-summer conditions, including moderate southerly flow, increasing humidity, and partial cloud cover ahead of the East Asian monsoon, are limiting strong daytime heating. Historical June climatology shows average highs near 26–28°C, with 27–29°C within one standard deviation. Recent short-range guidance has shown little shift toward extremes, keeping 29°C+ probabilities low at 8.5% and sub-25°C outcomes even less likely. Updated model runs expected over the next 48 hours will refine these ranges ahead of resolution.
