Trader sentiment for Tokyo’s July 24 maximum temperature centers on ensemble forecasts showing a likely peak near 32–33 °C, driven by persistent subtropical high pressure, clear to partly cloudy skies, and strong urban heat-island amplification in the Kanto plain. Recent model runs from the Japan Meteorological Agency and global ensembles indicate modest day-to-day variability tied to timing of any scattered showers or changes in boundary-layer mixing; lighter winds and higher dew points favor the upper end of the 31–34 °C range while increased cloud cover or sea-breeze effects could cap readings near 31 °C. Historical late-July climatology places average daily maxima around 31–32 °C, providing a baseline against which current model consensus is being weighed by traders.
