Persistent rain and thick cloud cover from a northerly flow are suppressing daytime heating in Tokyo on September 6, with official forecasts from the Japan Meteorological Agency and international models converging on a high of 23–24°C amid 90–100% precipitation chances and limited sunshine. This aligns with the market's tight clustering around those outcomes, as traders weigh model consensus against minor variations in rain timing or wind shifts that could allow brief clearing and a nudge toward 25°C. Historical September baselines near 27–28°C highlight how the current synoptic pattern deviates from typical conditions, with final JMA updates and real-time observations on the day serving as key resolution inputs.

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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
