**Clear, sunny conditions with light northeast winds are expected to drive Zhengzhou’s highest temperature on September 3, 2026, to the narrow 28–30 °C range that dominates trader positioning.** Multiple forecast models (including GFS, ECMWF-influenced runs, and local Chinese sources) converge on a daytime high of 29 °C or 30 °C under mostly clear skies and low humidity, consistent with early-September climatology for the North China Plain. Recent observations show stable high pressure, minimal cloud cover, and no incoming frontal systems or moisture that would alter the thermal profile. Light northeasterly flow (5–8 mph) supports modest mixing without significant advection of cooler or warmer air. This consensus places the strongest implied probability on 29 °C (36 %) and 30 °C (25 %), while the modest 12 % on 32 °C or higher reflects residual model spread and the small chance of slightly stronger insolation. Lower outcomes (27–28 °C) remain possible if boundary-layer mixing or timing of peak heating shifts, but current data favor the central cluster. No major forecast updates or synoptic changes have emerged in the past 24–48 hours to move these probabilities materially.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Zhengzhou Xinzheng International Airport Station in degrees Celsius on 3 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=zhcc
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.**Clear, sunny conditions with light northeast winds are expected to drive Zhengzhou’s highest temperature on September 3, 2026, to the narrow 28–30 °C range that dominates trader positioning.**
