Trader consensus on Polymarket reflects the latest forecast model consensus for Tokyo's highest temperature on April 3 at Haneda Airport station, with JMA's MSM run projecting 17.8°C, NOAA's GFS at 18.5°C, and ECMWF at 18.2°C—driving 38.5% implied odds for 18°C and 24.5% for 17°C. These align with early April climatology, where highs typically range 16-20°C amid mild spring highs influenced by weak high-pressure ridges and southerly flows, though partly cloudy skies and possible late rain per JMA guidance cap intensification potential. Recent overnight model updates tightened the spread to under 1°C, boosting mid-range outcomes while lowering 20°C+ to 13.5% combined; day-2 uncertainty (±2°C) persists, with new JMA bulletins and ensemble runs expected within 24 hours potentially shifting steering patterns.
