Trader consensus on Polymarket clusters tightly around 21–23°C for Beijing's highest temperature on March 27, with 22°C (25.5%) and 23°C (25.0%) leading, propelled by aligned ensemble forecasts from ECMWF and GFS models showing daytime peaks near 22°C under partly cloudy conditions. Recent developments include a stabilizing high-pressure ridge post-cold front, boosting solar insolation after northerly winds eased, while urban heat island effects in central Beijing could nudge readings higher than airport observations. Differentiating the frontrunners: thinner cloud cover favors 23°C via greater shortwave radiation absorption, versus denser overcast capping at 21°C through increased albedo; historical late-March highs average 16–19°C, highlighting this warmer signal amid early spring variability.

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 Beijing Capital International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/cn/beijing/ZBAA.
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.
