Trader consensus on Polymarket reflects tight clustering around 18–20°C for Tokyo's highest temperature on March 29, driven by Japan Meteorological Agency (JMA) forecast models projecting mild spring conditions under a high-pressure ridge. Recent ensemble runs from JMA and ECMWF indicate a warm southerly airflow boosting daytime highs into the upper teens to low 20s Celsius, with 19°C edging ahead due to urban heat island effects amplifying central Tokyo readings by 1–2°C over rural stations. Differentiating factors include variable cloud cover—potentially capping peaks at 18°C if thicker—or stronger insolation pushing toward 20–21°C; historical late-March averages hover at 16–17°C, but this year's neutral ENSO phase favors above-normal warmth. Daily JMA updates through March 28 will refine probabilities as surface observations integrate.

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.
