Current forecasts from the Japan Meteorological Agency and global models indicate Tokyo's July 14 minimum will likely fall near 25°C, consistent with historical July baselines of 22–25°C under typical summer humidity and light winds. Above-normal seasonal temperatures expected across Japan support the elevated 30°C-or-higher outcome priced at 44%, while cloud cover, urban heat-island effects, and radiative cooling rates create uncertainty around exact thresholds. Model consensus shows limited overnight cooling potential amid high dew points, with fresh JMA updates and ensemble runs likely to refine probabilities before resolution.
