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 15 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Recent forecasts from the Japan Meteorological Agency and AccuWeather project Tokyo's overnight low near 23–24°C for August 15, aligning with the market's leading 24°C outcome at 51.5% implied probability. This reflects typical midsummer radiative cooling limited by high humidity, urban heat island effects, and persistent Pacific high pressure, which suppress overnight temperature drops below climatological normals of 23.5–24°C. Model consensus shows minimal deviation expected, though variable cloud cover could allow slightly cooler readings around 23°C (26.0% implied). Updated JMA guidance ahead of resolution will clarify any shifts from current atmospheric patterns.
