This market will resolve to the temperature range that contains the highest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 13 Jul '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 for Tokyo indicate mostly cloudy skies with scattered showers possible on July 13, supporting maximum temperatures near 30–31°C and tempering the urban heat island effect amid typical mid-July humidity. This aligns with JMA’s broader summer 2026 outlook for above-normal seasonal temperatures while reflecting short-term model consensus favoring moderation over the 32°C seen on July 11. Traders’ heavy weighting toward 30–31°C outcomes captures these atmospheric conditions and the limited time for significant shifts before resolution, with cloud cover and precipitation as key variables that could cap peaks below seasonal averages.
