Trader consensus on Polymarket has locked in a 100% implied probability for Tokyo's lowest temperature on May 10 reaching exactly 16°C, backed by Japan Meteorological Agency (JMA) observations from the Tokyo (Haneda) AMEDAS station recording this minimum in the early morning hours amid partly cloudy skies and light winds. Urban heat island effects in central Tokyo, combined with insufficient radiational cooling overnight, stabilized temperatures above climatological norms of 14–16°C for mid-May, as confirmed by converging ECMWF and GFS model ensembles. While final daily data awaits official tabulation from Wunderground's RJTT records, a realistic challenge would require anomalous clear skies and calm conditions post-sunset to drive sharper cooling below 16°C—scenarios deemed improbable by current guidance.
