Official forecasts from agencies like the Korea Meteorological Administration point to a morning low near 18°C for Seoul on June 12, 2026, under mostly clear skies with light winds that limit overnight cooling. This aligns with early-summer climatology, where average lows hover around 16–19°C before monsoon humidity builds, and recent model runs show minimal deviation from that range. Trader consensus at 97% for 18°C reflects high confidence in these stable conditions and the resolution criteria tied to official daily minimum readings. Uncertainties could arise from unexpected cloud cover increasing radiative cooling or a late frontal passage altering temperatures by 1–2°C, though current guidance shows low probability of such shifts before resolution.
