Trader sentiment on Seoul's March 23 high temperature tilts toward 13-16°C outcomes, propelled by the Korea Meteorological Administration's latest forecast projecting 14-15°C under a mild southerly flow, corroborated by ECMWF and GFS ensemble means around 14°C. Recent model updates highlight divergence: ECMWF's warmer bias from stronger ridging contrasts GFS's cooler tilt tied to potential cold front remnants, amplifying uncertainty in peak hourly heat. Historical data shows March 23 averages near 12°C, but urban heat island amplification and spring's accelerating warming trends—evident in 2024's early mild spells—elevate odds for 16°C+, differentiating the tight race among top probabilities.
