Trader consensus on Polymarket heavily favors a Tokyo high of 15°C (30%) or 16°C (26%), driven by the Japan Meteorological Agency's latest forecast model ensemble projecting a peak around 15-16°C under a mild high-pressure ridge bringing southerly winds and partial sunshine. Differentiating these close outcomes are subtle uncertainties in boundary layer mixing and afternoon solar insolation—GFS and ECMWF runs show 15.5°C as the median, but urban heat island effects and variable cloud cover from an approaching front could nudge it higher to 16°C or cap it lower. Historical late-March averages hover at 14.5°C, with recent climate warming adding upside risk, though 14°C (18%) and 17°C (18%) reflect model spread as final observations loom.

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.
