Recent Japan Meteorological Agency forecasts for Tokyo indicate a minimum temperature near 25°C on July 16 amid cloudy conditions and possible rain, reflecting typical midsummer humidity and limited nocturnal cooling. Ensemble model spreads and steering patterns introduce uncertainty between 24–27°C, with urban heat island effects and cloud cover as key variables that can elevate overnight lows above climatological averages of 23–24°C. Trader consensus around 26–30°C outcomes captures this forecast variability and the potential for slight warming under stalled frontal systems, while lower probabilities on 21°C or below align with the low historical likelihood of significant cold advection in peak July. Updated model runs and official briefings over the next 48 hours will likely refine these ranges as land-sea breeze influences clarify.
