Recent Japan Meteorological Agency forecasts and ensemble model runs indicate a daytime high near 28–29°C for Tokyo on May 18 under partly cloudy skies and light southerly flow, positioning 28°C or higher as the leading outcome at 51% implied probability. This exceeds the mid-May climatological normal of 22–24°C at the Otemachi reference station, driven by above-average insolation and a strengthening subtropical ridge that limits cloud cover and enhances afternoon heating. Trader positioning also reflects uncertainty from possible scattered showers, which could cap temperatures near 27°C at 28.5% probability if they arrive earlier than currently modeled. Updated JMA guidance and satellite observations over the next 48 hours will refine these thresholds before resolution.

The resolution source for this market will be information from Wunderground, specifically the highest 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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
