Ensemble weather models from agencies like the Japan Meteorological Agency show the highest daily temperature in Tokyo on August 25 most likely reaching 33–34°C, with modest spread across runs due to uncertainty in afternoon sea-breeze strength and cloud cover. Subtropical high pressure is expected to maintain hot, humid conditions typical of late-summer climatology, but small shifts in wind direction or timing of any frontal passage could push the maximum a degree lower or higher. Historical August maxima in central Tokyo average near 32–33°C, providing context for why traders assign roughly one-third probability to 34°C and nearly one-quarter to 33°C. New model guidance expected within 24 hours could narrow the range.
