**Market-implied odds favor a Tokyo minimum temperature of 24°C on August 3, reflecting climatological norms and short-term model guidance.** Japan Meteorological Agency data show the daily normal minimum for early August near 23.9°C, while broader summer 2026 outlooks indicate above-normal temperatures nationwide. Current forecasts for August 3 describe cloudy conditions that typically limit overnight radiative cooling, supporting overnight lows in the 24–26°C range. AccuWeather monthly guidance places typical August lows between roughly 22–28°C, with trader consensus clustering tightly around the 24–25°C outcomes. Key resolution factors include official JMA observations from Tokyo’s primary stations; any shift in steering patterns or increased cloud cover could nudge the minimum slightly lower, though historical analogs and the current warm seasonal baseline keep extremes below 22°C or above 27°C at low probability. Updated JMA three-day forecasts and ensemble model runs over the next 48 hours will provide the clearest near-term signal for position adjustments.
