Trader consensus on Polymarket heavily favors a Tokyo high of 16°C (27%) or 17°C (25.5%) for March 24, driven by the latest Japan Meteorological Agency (JMA) ensemble forecasts projecting afternoon peaks in the mid-teens Celsius amid a persistent high-pressure ridge over eastern Japan. This setup overrides seasonal norms of around 14°C by advecting warmer southerly air, but model spread—ECMWF leaning slightly cooler at 16°C due to potential afternoon cloud incursions, while GFS hints at 17°C under clearer skies—explains the razor-thin odds separation. Urban heat island effects and precise timing of the diurnal maximum further amplify uncertainty, with traders eyeing hourly observations for resolution catalysts.

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.
