Recent meteorological observations and numerical weather prediction models show Shanghai's daily maximum temperature on September 18 reaching 29°C amid mostly cloudy skies, northeast winds of 5–10 km/h, and high humidity near 65–75 percent that limits daytime heating. Midday readings at multiple stations have stabilized around 28–29°C, consistent with late-summer climatology for the region and official forecasts projecting no significant afternoon surge. Trader consensus reflected in the 99.7 percent implied probability for 29°C aligns with this data convergence, though final resolution depends on the precise peak recorded by authorized meteorological stations. A stronger-than-expected break in cloud cover or a temporary wind shift could still push the official high to 30°C before sunset.

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=zspd
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.
