**Forecast consensus from official sources and models positions a daily maximum near 30–31 °C as the most likely outcome for Shenzhen on September 16, 2026.** Partly cloudy to mostly cloudy skies, southeasterly winds around 2–4 m/s, and isolated short-duration showers are limiting daytime heating, consistent with recent observations showing peaks of 30–31 °C amid 65–80 % relative humidity. Subtropical September climatology in the Pearl River Delta favors highs in this narrow range when monsoon moisture and cloud cover persist, reducing solar insolation compared with clearer periods. Real-time data from the Shenzhen Meteorological Station and national grid observations through midday support this trajectory, with minimal model spread across runs. Traders’ heavy weighting on 30 °C reflects the tight clustering of authoritative forecasts and the low probability of rapid clearing that would push readings to 32 °C or higher before evening.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=zgsz
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
