Trader consensus on Polymarket heavily favors a Tokyo high temperature of 15°C (30.5% implied probability) for March 23, closely trailed by 14°C and 16°C at 26% each, driven primarily by the Japan Meteorological Agency's (JMA) latest forecast projecting a daytime peak near 15°C under partly cloudy skies with light southerly winds boosting mild early-spring warmth. Differentiating factors include subtle model divergences—global ensembles like ECMWF hint at slightly cooler 14°C outcomes if afternoon clouds thicken, while higher-resolution local runs support 16°C with sustained sunshine—against Tokyo's historical March 23 average high of 13°C, elevated by urban heat island effects and recent above-normal trends. Resolution hinges on official JMA observations from the Tokyo station by midnight UTC.
