Current forecasts from regional meteorological models indicate a highest temperature in Beijing on May 22 most likely between 20°C and 22°C, driven by a slow-moving high-pressure system that limits daytime heating while allowing scattered cloud cover and light showers to moderate afternoon peaks. Ensemble runs show modest variability tied to exact timing of any frontal passage and boundary-layer moisture, producing the tight clustering of market-implied odds around these three outcomes. Historical May climatology places average daily maxima near 26°C, yet recent upstream cold-air advection has kept readings several degrees below seasonal norms, consistent with the observed downward shift in probabilities. Updated guidance from official monitoring agencies is expected later today and will refine land-surface temperature projections ahead of market 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 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.
