Trader consensus heavily favors a Tokyo high of 16°C on March 22 (43.5% implied probability), driven by the latest Japan Meteorological Agency (JMA) forecasts and ECMWF ensemble models projecting mild southerly flow amid a high-pressure ridge over the Sea of Japan, which has boosted early spring temperatures. Recent observations show Tokyo's March 20 high at 17°C and 21st preliminaries near 15°C, aligning with this warmer-than-average pattern—historical March 22 averages hover around 14°C but have trended upward 1-2°C in recent decades due to urban heat island effects and climate variability. Lower odds for 15°C (26.5%) and 17°C (23.5%) reflect model spread and diurnal uncertainties, with minimal support for extremes as sea surface temperatures remain moderate. Upcoming JMA updates at 0600 JST could shift odds further.
