Trader consensus on Polymarket heavily favors 17°C (30.5%) and 16°C (27.5%) as Tokyo's highest temperature on March 24, driven by Japan Meteorological Agency's latest forecast projecting a daytime high of 17°C under a stable high-pressure ridge bringing mild southerly winds and partial sunshine. Differentiating factors include ensemble model spread—ECMWF leans warmer at 17-18°C due to urban heat island amplification in central Tokyo, while GFS variants suggest 16°C if low-level clouds persist from residual frontal moisture. Historical March 24 highs average 13-15°C, but this year's early spring warmth has narrowed uncertainty around these outcomes, with upcoming 12Z model updates poised to shift odds further.
