Ensemble weather model forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) and Global Forecast System (GFS), corroborated by AccuWeather and China Meteorological Administration guidance, cluster Shenzhen's highest temperature on March 29 around 26–28°C under a persistent subtropical high-pressure ridge driving warm southerly winds from the South China Sea. This tight spread explains trader consensus favoring 27°C (32.5% implied probability) and 26°C (28.0%) nearly equally, with 28°C (20.5%) close behind, as variable cloud cover and moderating sea breezes introduce uncertainty in peak daytime solar insolation and potential late-afternoon showers capping heating. A recent warm spell peaked at 29°C on March 26—well above March climatological norms of 23–24°C—but rising humidity signals moderation; monitor afternoon model updates for convective shifts before resolution via official Shenzhen Bao'an Airport observations.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column on the specified date once information is finalized for all hours on that date, available here: https://www.weather.gov/wrh/timeseries?site=zgsz
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve to "Yes" until 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.
