Official forecasts from the Japan Meteorological Agency indicate Tokyo will record a daily minimum of 19°C on June 2, driven by a stable high-pressure ridge suppressing nocturnal cooling under partly cloudy skies and light southerly flow. Ensemble guidance shows minimal spread around this value, consistent with early-summer climatology where overnight lows typically stabilize near 18–20°C absent frontal passages or strong radiational cooling. Traders assign near-certainty to the 19°C outcome because real-time observations through the evening window are unlikely to deviate by more than 1°C. Only an unanticipated late surge in onshore winds or measurement-site anomaly could shift the recorded low, scenarios models currently rate as remote.

This market will resolve to the temperature range that contains the lowest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 2 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.Official forecasts from the Japan Meteorological Agency indicate Tokyo will record a daily minimum of 19°C on June 2, driven by a stable high-pressure ridge suppressing nocturnal cooling under partly cloudy skies and light southerly flow.
