Current Japan Meteorological Agency forecasts and ensemble models indicate overnight lows near 23–24°C in Tokyo on August 13, driven by a persistent Pacific high-pressure system, elevated humidity, increasing cloud cover, and scattered showers that limit nighttime radiative cooling. These conditions align with the market’s leading outcomes at 23°C (45.5%) and 24°C (33.5%), reflecting trader consensus on the latest model guidance amid a broader summer pattern of above-normal temperatures. Resolution hinges on official daily minimum readings, with fresh JMA updates and refined model runs expected to refine probabilities ahead of the date.
