Will the highest temperature in Seoul be 16°C or higher on March 23?

Analysis

1-day weather forecasts are highly accurate, and multiple models support the market's 52% probability for 16°C+. KMA projects 15°C peak with ECMWF showing warmer bias toward 16°C+, while GFS favors 14°C. The tight clustering around 14-16°C creates legitimate uncertainty. Key factors supporting 16°C+: Urban heat island effects at Incheon Airport, weakening Siberian High allowing southerly flow, and ECMWF's consistent warm bias. Historical March averages of 11-13°C could be exceeded. However, the outcome hinges on a single degree difference with significant model disagreement. The $10k+ trading volume suggests informed meteorological analysis is already priced in. Staying close to market consensus - no strong information edge over professional weather models and experienced traders.
