Persistent heat wave conditions across the Seoul-Incheon region, reinforced by Korea Meteorological Administration heat emergency warnings, drive trader consensus toward a 34–35°C peak on August 8 at the official Incheon station. Forecast models and short-range guidance indicate clear skies, light easterly winds, and high humidity that favor strong daytime heating without significant cloud cover or precipitation to moderate temperatures. Recent days have recorded maxima of 33–35°C under similar synoptic patterns, aligning with climatological August baselines near 30–31°C while reflecting the current elevated thermal regime. Model consensus remains tight for this 24-hour window, though minor steering shifts or localized sea-breeze effects could nudge the exact maximum within the narrow 34–36°C range favored by market-implied probabilities.
