Recent Japan Meteorological Agency forecasts indicate a minimum temperature near 24°C for Tokyo on August 6 under cloudy conditions, aligning with the seasonal normal of 23.9°C and limited nighttime radiative cooling from high humidity and cloud cover. Trader consensus clustering on 25–26°C reflects the urban heat island effect in central Tokyo, where concrete and reduced sky view factors typically elevate overnight lows by 1–2°C above rural baselines, plus minor spread in ensemble model runs from global guidance. With resolution hinging on official JMA observations at the central station, any clearer skies or stronger winds could allow modest additional cooling toward the lower tail of probabilities.
