Trader consensus locks in 15°C as Tokyo's highest temperature on March 23, propelled by Japan Meteorological Agency (JMA) observations and models confirming a daytime peak of exactly 15°C amid a stable cool air mass, light winds, and partial cloud cover limiting solar insolation. Hourly data from Haneda and central Tokyo stations show morning lows near 10°C rising modestly, aligning with late-March climatological norms of 12–15°C highs during transitional spring patterns. This positioning reflects low model divergence, with ECMWF and GFS ensembles converging on subdued advection. Realistic challenges include an unforeseen clear-sky surge boosting surface heating to 16°C or minor station microclimate variations, though probabilities remain negligible given real-time verifications.

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.
