A strengthening high-pressure ridge over the Kanto Plain is the primary driver behind traders assigning a 76% implied probability to Tokyo reaching 28°C or higher on May 18, as official Japan Meteorological Agency guidance points to clear skies, light southerly flow, and intense afternoon solar heating that should push maximum temperatures into the upper 20s. Ensemble model runs cluster tightly around 28–30°C with minimal spread, well above the mid-May climatological average of 23–25°C at the reference station. Recent surface observations and the latest model updates have reinforced this warm setup, leaving little room for cooler outcomes and aligning market sentiment with the expected diurnal peak tomorrow.
