Japan Meteorological Agency ensemble forecasts project an overnight low of 14–16°C for Tokyo on May 24, closely matching the historical May climatology of roughly 15°C. Current atmospheric conditions, including stable westerly flow and absence of significant cold-air advection, support this range, with model consensus showing minimal spread. Trader positioning at 100% for 15°C reflects this alignment between official guidance and typical seasonal baselines. A late-arriving frontal system or rapid radiative cooling under clear skies could push readings toward 13°C or below, though such shifts remain outside the primary forecast envelope as of the latest model runs.

This market will resolve to the temperature range that contains the lowest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 24 May '26.
The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day by the Forecast for the Tokyo Haneda Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized.
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.
