Recent numerical weather prediction models from the China Meteorological Administration and international ensembles indicate Beijing’s May 17 high temperature will peak near 19 °C under stable atmospheric conditions with light southerly flow and partly cloudy skies. Official observations at Beijing Capital International Airport and urban stations align with this consensus, reflecting typical mid-May climatology where daily maxima average in the low-to-mid 20s °C but are tempered today by modest cloud cover and limited surface heating. Trader positioning at 99.9 % for the 19 °C outcome captures this model agreement and real-time data, while the slim probabilities for adjacent values acknowledge residual uncertainty in boundary-layer mixing or localized urban heat effects that could still shift the recorded maximum by one degree before 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.
