Recent JMA forecasts for Tokyo on June 18 project a minimum near 19°C under cloudy conditions with scattered showers, yet trader consensus clusters tightly on 20–21°C implied probabilities exceeding 80% combined. This positioning reflects model spread in nocturnal radiative cooling rates, where partial cloud cover and urban heat island effects can elevate overnight lows above official guidance. El Niño-enhanced warmth across the western Pacific adds upward bias to ensembles, while precipitation timing remains the key variable that could shift outcomes by 1–2°C. Updated JMA and global model runs through June 17 will likely refine these thresholds ahead of market resolution.
