Recent Japan Meteorological Agency forecasts indicate mostly cloudy skies over Tokyo through June 22, limiting overnight radiative cooling and supporting minimum temperatures near 19–21°C amid the early tsuyu rainy season transition. Seasonal outlooks from the agency project above-normal warmth for June–August 2026 due to a stronger Pacific High, consistent with historical late-June lows averaging around 19–20°C. Model consensus on cloud thickness and any scattered showers introduces modest uncertainty in exact diurnal minima, driving the tight market clustering between 20°C and 21°C outcomes while keeping lower or higher extremes at reduced implied probabilities.

This market will resolve to the temperature range that contains the lowest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 22 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.Recent Japan Meteorological Agency forecasts indicate mostly cloudy skies over Tokyo through June 22, limiting overnight radiative cooling and supporting minimum temperatures near 19–21°C amid the early tsuyu rainy season transition.
