Trader consensus on Polymarket's closely contested odds for Tokyo's highest temperature on May 15—24°C at 33.5%, 23°C at 28.5%, and 25°C at 24.0%—reflects genuine uncertainty in Japan Meteorological Agency (JMA) forecast models amid a weak high-pressure ridge ushering mild southerly airflow. Recent days featured highs of 24–26°C under similar setups, but today's (May 14) scattered showers introduce carryover cloudiness that could cap peaks at 23°C via reduced solar insolation, while clearer midday skies might push to 25°C through enhanced urban heating. Historical mid-May averages hover near 23°C, with sea breeze timing as a key differentiator; JMA hourly updates tomorrow will sharpen resolution based on Tokyo station observations.
