**Forecast models for Guangzhou on September 18, 2026, converge on a daily maximum near 34–35 °C under partly cloudy skies, light easterly winds, and negligible precipitation.** This setup favors strong daytime solar heating in the region’s subtropical monsoon climate, where September averages historically reach about 31.8 °C. Current observations from September 17 show highs near 32–33 °C with similar conditions, supporting modest further warming without significant cloud cover or rain to limit insolation. Multiple sources, including numerical guidance, project afternoon peaks of 33–35 °C, aligning with the market’s leading implied probabilities for 35 °C (47.5 %) and 36 °C (28.5 %). Lower outcomes like 34 °C receive less weight because recent model runs and analogs indicate limited cooling influence from the weak pressure gradient. Resolution will hinge on official station readings, with any late-day thunderstorm development or slight model shifts in moisture the main variables that could alter the final maximum.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Guangzhou Baiyun International Airport Station in degrees Celsius on 18 Sep '26.
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=zggg
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.**Forecast models for Guangzhou on September 18, 2026, converge on a daily maximum near 34–35 °C under partly cloudy skies, light easterly winds, and negligible precipitation.**
