Observations at Tokyo's Haneda Airport—the market's official resolution station—confirm a peak temperature of 18°C reached earlier today under a cool air mass and persistent cloud cover, as reported by the Japan Meteorological Agency (JMA). Southerly winds and scattered showers have limited solar insolation and daytime heating, aligning with JMA's latest model guidance projecting subdued maxima around 19°C but yielding lower actuals. Trader consensus at 100% reflects this observational data, with the sun setting soon minimizing upside risk. A late-day clearance of clouds could theoretically allow a brief spike, though current downward trends and historical late-afternoon patterns in similar synoptic setups make higher outcomes improbable. Final JMA tallies expected post-midnight.
