Recent forecasts from the Japan Meteorological Agency indicate mostly cloudy conditions with scattered showers possible over Tokyo on July 13, following a pattern of seasonal monsoon influences. These factors typically moderate overnight radiative cooling, supporting minimum temperatures in the 23–26°C range consistent with historical July baselines near 22–24°C. Trader consensus across closely matched probabilities reflects uncertainty in exact cloud cover, precipitation timing, and urban heat island effects, which can elevate lows by 1–2°C compared to rural analogs. Upcoming model updates from regional agencies will refine wind patterns and humidity levels that determine whether the minimum settles nearer the lower or upper end of this band.
