Tight clustering of market-implied odds around 20–23°C reflects the latest ensemble forecasts from ECMWF and GFS models, which project Chengdu's March 21 high temperature in this narrow range amid mild spring conditions. Historical data from the China Meteorological Administration shows average March highs near 18°C, but recent upper-level ridging over eastern China and southerly flow have nudged projections warmer, favoring 22–23°C at 51.5% combined probability over cooler 19–21°C outcomes. Differentiating factors include model spread from potential afternoon cloud cover suppressing peaks versus urban heat island amplification in Chengdu's basin; traders await 00Z model runs for resolution amid low ensemble variance. Baseline uncertainty stems from microscale topography and pollution aerosols influencing surface readings.

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 Chengdu Shuangliu International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/cn/chengdu/ZUUU.
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.
