Latest numerical weather prediction models from the China Meteorological Administration converge on a daily maximum of 28°C for Wuhan on May 17, supported by light southerly flow beneath a modest subtropical ridge that favors daytime warming with partial cloud cover limiting further gains. This aligns with May climatology around the region, where average highs reach 26–29°C, and recent observational trends from the Wuhan Tianhe International Airport station showing consistent peaks near this threshold. Trader consensus on Polymarket has priced the 28°C outcome at near-certainty, reflecting the narrow uncertainty range in short-range ensemble guidance. A sudden increase in insolation from unexpected clear skies or a shift in steering winds could still push readings to 29–30°C, though current model agreement makes such deviations unlikely 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 Wuhan Tianhe International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/cn/wuhan/ZHHH.
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.
