Trader consensus on Polymarket heavily favors a Tokyo high temperature of 19°C (55.5% implied probability), closely followed by 20°C (37.5%), driven by the Japan Meteorological Agency's (JMA) evening forecast from March 29 projecting exactly 19°C amid cloudy skies turning partly cloudy later, with 20% morning precipitation chance dropping to 10% afternoon. This reflects a mild southerly airflow pattern continuing from March 29's observed 21°C peak, warmer than the late-March climatological average of 14–15°C, boosted by high-pressure ridging. Model consensus shows tight uncertainty around peak afternoon heating, with cloud cover potentially capping intensity below 21°C (8.3%). JMA surface observations will track hourly maxima through evening for final resolution.

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.
