Persistent rain, extensive cloud cover, and northerly flow have suppressed daytime heating across the Tokyo region on September 11, 2026, keeping maximum temperatures near 20–21 °C according to consensus model guidance and surface observations. High humidity near 90 % and steady precipitation reduce solar insolation and evaporative cooling, limiting the diurnal rise that would otherwise occur under clearer September conditions. Market-implied odds strongly favor 21 °C because official forecasts from agencies such as the Japan Meteorological Agency align with this narrow range, reflecting both current mesoscale conditions and the low likelihood of rapid clearing before peak heating hours. A sudden break in cloud cover or a shift to southerly winds could allow modest additional warming toward 22 °C, though model agreement on continued overcast skies and light northeasterly flow makes such an outcome unlikely before resolution.

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.
