Trader consensus on Polymarket prices a tight cluster of outcomes around 16–19°C for Tokyo's highest temperature on April 3, reflecting the latest Japan Meteorological Agency short-range forecasts and global model ensembles like ECMWF and GFS, which show peak afternoon highs in this range amid mild spring conditions. Early April climatology supports this, with historical daily maximums averaging 17°C and a typical range of 12–22°C, influenced by increasing southerly winds and solar heating as La Niña transitions to ENSO-neutral (60% probability per NOAA by April). Differentiating factors include model spread on cloud cover suppressing highs at 16°C versus clearer skies or urban heat island effects boosting to 19°C; uncertainty persists due to variable boundary layer mixing and potential frontal passages. JMA updates expected daily through resolution.
