Recent model consensus from the China Meteorological Administration, ECMWF, and GFS places Guangzhou’s May 18 daytime maximum near 27–29°C under a moderating subtropical ridge with scattered convective clouds and patchy rain possible. These conditions create tight uncertainty around the daily peak: sufficient solar heating could push readings to 29°C if breaks develop by midday, while sustained cloud cover or earlier showers would cap the high closer to 27°C. Historical May averages near 29–30°C provide context, yet short-range variability in humidity and boundary-layer mixing keeps adjacent temperature bins closely contested in trader pricing ahead of final forecast updates.

This market will resolve to the temperature range that contains the highest temperature recorded at the Guangzhou Baiyun International Airport Station in degrees Celsius on 18 May '26.
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 Guangzhou Baiyun International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/cn/guangzhou/ZGGG.
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.Recent model consensus from the China Meteorological Administration, ECMWF, and GFS places Guangzhou’s May 18 daytime maximum near 27–29°C under a moderating subtropical ridge with scattered convective clouds and patchy rain possible.
