Trader consensus on Polymarket heavily favors a Tokyo high of 16°C (50% implied probability) on March 22, driven by Japan Meteorological Agency (JMA) and ECMWF model forecasts converging on 15-17°C amid a stable high-pressure ridge over eastern Japan. Recent observations show March 20's verified high of 14°C and March 21's preliminary 15°C, aligning with seasonal norms where Tokyo's March average peaks at 13.8°C but this year's mild La Niña-influenced pattern has boosted early spring warmth. Lower odds for extremes reflect low volatility in urban heat island-moderated forecasts, with traders eyeing JMA's evening update for potential shifts.
