Latest ensemble forecasts position Busan’s June 12 high near 28–29 °C, reflecting a weak warm ridge and southerly flow over the Korean Peninsula that favors modest warming above early-June climatology of 23–26 °C. Coastal marine influence and possible afternoon sea breezes introduce downward bias relative to inland sites, while variable cloud cover and any early Changma moisture could trim peak readings by 1–2 °C. Model spread between ECMWF and KMA runs, plus uncertainty in exact frontal timing, keeps 28 °C and 29 °C probabilities closely matched, with upside risk to 30 °C if clearer skies allow stronger daytime heating.
