Cloudy skies and scattered showers across Tokyo on August 27 are suppressing solar heating and limiting the daily maximum to around 30°C, consistent with Japan Meteorological Agency forecasts and real-time observations showing mid-day readings near 29°C under high humidity and light winds. Model consensus from multiple sources highlights reduced insolation from persistent cloud cover and precipitation probability exceeding 50% during peak heating hours, aligning with climatological August patterns where such conditions typically cap highs near or below the 30.1°C normal. Trader consensus at 99.8% implied probability for 30°C reflects this strong observational and forecast alignment, though a sudden clearing trend could allow brief intensification to 31°C before resolution.

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 27 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.Cloudy skies and scattered showers across Tokyo on August 27 are suppressing solar heating and limiting the daily maximum to around 30°C, consistent with Japan Meteorological Agency forecasts and real-time observations showing mid-day readings near 29°C under high humidity and light winds.
