This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Tokyo Haneda Airport Station in degrees Celsius on 29 Aug '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=rjtt If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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.Persistent cloud cover, widespread rain, and northeasterly flow across the Kanto region are suppressing daytime heating in Tokyo on August 29, 2026, producing observed and model-forecast highs of 24–27 °C according to Japan Meteorological Agency guidance and ensemble runs. These conditions align with the near-100 % market-implied probability on a 27 °C peak at the Haneda station, reflecting the narrow band of plausible outcomes once final NOAA data are recorded. A sudden reduction in cloud cover or rainfall could permit additional insolation and push readings modestly higher, yet current observational trends and short-range model consensus make such a shift unlikely before resolution.
