Recent Japan Meteorological Agency ensemble forecasts peg Tokyo's March 26 high at around 13°C, driving trader consensus with 28% implied probability on that outcome amid tight clustering from 11-15°C. This reflects a mild high-pressure ridge over the Kanto region, fostering above-normal spring temperatures following a cool anomaly earlier in the month, while historical March averages hover near 12°C. Differentiating factors include potential diurnal cloud variations and light southerly winds boosting urban heat island effects by 1-2°C, versus overnight cooling risks under clearer skies pushing toward 11-12°C; 16°C+ odds at 15.5% capture upside tail risk from stronger warm advection, but core models converge below 15°C. Traders eye tomorrow's 12Z update for resolution shifts.

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.
