**Latest Japan Meteorological Agency guidance points to a mostly cloudy day with a forecast maximum of 31°C for Tokyo on August 31, yet multiple numerical models cluster nearer 29–30°C amid persistent easterly flow and high humidity.** Marine air advection, widespread stratiform cloud cover, and light drizzle potential are limiting daytime heating compared with recent clearer spells earlier in the month. Traders appear to weigh the official deterministic forecast against ensemble spreads and observed boundary-layer moisture that typically caps urban highs 1–2°C below guidance on similar setups. With resolution hinging on exact insolation and any afternoon showers, the near-even split between 29°C and 30°C reflects genuine uncertainty in the final observed maximum at the official Tokyo station.

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 31 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 for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the 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.**Latest Japan Meteorological Agency guidance points to a mostly cloudy day with a forecast maximum of 31°C for Tokyo on August 31, yet multiple numerical models cluster nearer 29–30°C amid persistent easterly flow and high humidity.** Marine air advection, widespread stratiform cloud cover, and light drizzle potential are limiting daytime heating compared with recent clearer spells earlier in the month.
