Recent Korea Meteorological Administration forecasts and supporting models indicate a high around 32–33°C for Incheon on August 18, driven by continued warm, humid summer conditions with mostly sunny morning skies giving way to increasing afternoon cloud cover. Trader consensus favoring 30–31°C (combined ~62.5% implied probability) reflects uncertainty from potential marine moderation at the coastal Incheon site, variable afternoon convection, and any last-minute forecast shifts that could cap the daily maximum below official guidance. Historical August baselines near 30–31°C provide additional context, with low odds on extremes underscoring the narrow expected range ahead of final observational data.
