Trader consensus on Polymarket reflects tight uncertainty in short-range forecasts for Tokyo's highest temperature on March 29, with 19°C (26%) edging 18°C (25%) amid mild spring conditions driven by a lingering high-pressure system over Japan. Japan Meteorological Agency (JMA) models and global ensembles like ECMWF and GFS show a spread of 17–21°C, influenced by variable cloud cover from an approaching cold front, southerly winds advecting warmer air, and Tokyo's urban heat island effect boosting readings by 1–2°C above rural areas. Historical late-March averages hover around 14–15°C, but this year's positive temperature anomalies from a weak La Niña transition add upside risk. JMA's next update later today could refine the outlook as upper-air patterns stabilize.
