Recent forecasts indicate persistent cloud cover and scattered showers across Tokyo on August 29, limiting daytime heating and supporting peak temperatures near 27–28°C. Official guidance from the Japan Meteorological Agency highlights cloudy conditions with occasional rain, consistent with multiple global models showing suppressed maxima relative to the late-August climatological average of around 30–31°C. Variable steering patterns and precipitation timing create the narrow spread in market-implied odds, as even modest shifts in cloud breaks or rainfall intensity can alter the daily high by 1–2°C. Traders appear to weigh the strong consensus for a cooler, unsettled day against residual uncertainty in short-range model solutions ahead of final observational data.

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.
