Trader sentiment for Tokyo's June 21 minimum temperature clusters around 21–22°C because ensemble forecasts show persistent cloud cover and scattered showers associated with the early Tsuyu rainy season moderating overnight radiative cooling. Recent Japan Meteorological Agency guidance indicates a frontal influence keeping daytime maxima near 25–26°C while limiting nocturnal drops, consistent with climatological June lows of 19–21°C. Model spread in boundary-layer moisture and wind patterns creates the observed probability distribution, with lower outcomes (18–20°C) possible only under clearer breaks and higher values (23°C+) if subtropical ridging strengthens. Updated high-resolution runs and satellite trends over the next 48 hours will refine the diurnal temperature range ahead of market resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 21 Jun '26.
The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the Tokyo Haneda Airport Station, available here: https://www.wunderground.com/history/daily/jp/tokyo/RJTT.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.Trader sentiment for Tokyo's June 21 minimum temperature clusters around 21–22°C because ensemble forecasts show persistent cloud cover and scattered showers associated with the early Tsuyu rainy season moderating overnight radiative cooling.
