Recent Japan Meteorological Agency forecasts peg Tokyo's March 23 high at 15-16°C, anchoring trader consensus around those outcomes with 21.5% and 19.5% implied probabilities, respectively, amid tight clustering from 14-17°C. This reflects a high-pressure ridge stabilizing mild spring air masses over Honshu, boosting solar insolation for daytime peaks, though divergent ECMWF and GFS ensembles introduce uncertainty—some runs dip to 14°C under partial cloud cover from a weakening northern front, while warmer outliers hit 18-19°C with clearer skies. Historical late-March averages hover near 14°C, but urban heat island effects and above-normal Pacific sea surface temperatures tilt odds warmer, differentiating leaders via model spread on boundary layer mixing and frontal timing. Traders eye JMA's evening update for resolution cues.

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.
