Tokyo's peak summer conditions, driven by persistent high-pressure systems and urban heat island effects, align with official forecasts from the Japan Meteorological Agency projecting a daily maximum of 34°C for August 8. August climatology shows typical Tokyo highs of 31–35°C amid high humidity exceeding 70%, with recent model consensus from regional monitoring reinforcing this narrow outcome. Trader consensus at 100% implied probability reflects verified observational baselines and short-term forecast stability. A rapid shift from unexpected cloud cover, stronger sea breezes, or measurement discrepancies at official stations could alter the recorded high, though such deviations remain low-probability given current atmospheric patterns.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 8 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Tokyo Haneda Airport Station, available here: https://www.wunderground.com/history/daily/jp/tokyo/RJTT.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
