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 15 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. 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 Japan Meteorological Agency forecasts project a Tokyo maximum of 29°C on August 15 under cloudy skies with scattered showers, aligning with the market's tight clustering around 29–30°C. Persistent cloud cover from a moderating Pacific high and possible precipitation timing limit daytime heating by reducing solar insolation, while urban heat island effects and humidity near 70–80% could add marginal warming. Minor shifts in forecast model runs—such as delayed showers or clearer intervals—differentiate outcomes between 28°C and 31°C, with historical mid-August normals near 31°C providing a baseline. Updated JMA guidance ahead of the date remains the key catalyst for trader adjustments.
