Trader consensus on Polymarket heavily favors a Tokyo high of 16°C (38.5% implied probability) or 17°C (29.5%), reflecting the latest Japan Meteorological Agency forecasts showing ensemble model means around 16.5°C for March 22, driven by a persistent high-pressure ridge ushering in mild continental air masses over the Kanto region. Differentiating factors include cloud cover variability—clearer skies could push toward 17°C via enhanced solar insolation, while incoming mid-level clouds from the Pacific might cap at 15°C (24% odds)—against historical late-March averages of 13-14°C. Recent GFS and ECMWF updates reduced 18°C+ odds amid slight cooling signals, underscoring typical spring forecast uncertainty from jet stream wavering.
