Official forecasts from the Japan Meteorological Agency and numerical models project Tokyo’s minimum temperature on August 29 near 20–21 °C, driven by widespread cloud cover, light rain, and northeasterly flow that limit radiational cooling while keeping daytime maxima suppressed around 24–26 °C. Recent surface observations confirm overnight readings stabilizing in this narrow band, consistent with the market’s heavy weighting on 21 °C (55 %) and 20 °C (36 %). These conditions contrast with the long-term August normal minimum of approximately 22.5 °C, reflecting the influence of an active frontal boundary and above-average precipitation this month. Traders are monitoring final Japan Meteorological Agency station data at Haneda and Otemachi for resolution, with little scope for deviation absent rapid clearing.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Tokyo Haneda Airport Station in degrees Celsius on 29 Aug '26.
The resolution source for this market will be information from NOAA, specifically the lowest 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.Official forecasts from the Japan Meteorological Agency and numerical models project Tokyo’s minimum temperature on August 29 near 20–21 °C, driven by widespread cloud cover, light rain, and northeasterly flow that limit radiational cooling while keeping daytime maxima suppressed around 24–26 °C.
