Tokyo's minimum temperature on August 13 is expected to settle near 23–24°C amid persistent summer humidity and a forecast of thunderstorms or showers, which limit nocturnal radiative cooling and support higher overnight readings. Climatological normals from the Japan Meteorological Agency place the average August low at 23.7°C, while urban heat-island effects and elevated dew points commonly keep Tokyo minima above rural benchmarks. Recent model consensus and short-range guidance indicate partly cloudy to stormy conditions that could prevent deeper cooling below 23°C, though any clearing overnight might allow a dip toward that threshold. Traders appear to weigh these dynamics against the narrow resolution window, with implied probabilities concentrated on the 23–24°C band reflecting both baseline expectations and the latest precipitation outlook.

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.
