Trader consensus on Polymarket tilts toward a Tokyo high of 19°C (39%) on March 29, driven by the latest Japan Meteorological Agency (JMA) forecast models showing peak daytime temperatures in the upper teens Celsius under a dominant high-pressure ridge advecting mild southerly air from the Pacific. Recent observations confirm the warming trend, with March 27 highs hitting 17-18°C amid low cloud cover and minimal precipitation risk, aligning with ensemble guidance for solar-driven peaks near 19-20°C while 18°C (16.5%) accounts for potential afternoon cloudiness. Seasonal March averages hover around 13°C, but current positive temperature anomalies—boosted by neutral ENSO conditions—elevate implied odds for above-normal warmth; traders await intraday JMA updates for final positioning amid typical diurnal forecast uncertainties.
