Current short-range forecasts from agencies like the Japan Meteorological Agency and global models indicate Tokyo nighttime minima near 23–24°C for August 13, driving the tight 43.5%/39.5% split between those outcomes. Persistent influence of the strengthened Pacific High sustains elevated humidity and limits radiative cooling overnight, while Tokyo’s urban heat island retains warmth from preceding days with highs near 30–32°C. Minor model differences hinge on expected cloud cover, light winds, and any localized shower activity that could enhance or suppress cooling rates by 1–2°C. With resolution in under 48 hours, traders closely track updated ensemble runs for any shifts in boundary-layer conditions.

This market will resolve based on the lowest 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 lowest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 13 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
