**Forecast consensus for Shanghai on September 20, 2026, centers on a daily maximum of 28–29°C, aligning with the market’s heavy weighting toward those two outcomes (50% and 37%).** Multiple global and regional models, including GFS-derived guidance and agency outlooks, project partly cloudy to mostly sunny conditions with northeast winds of 8–15 km/h moderating temperatures after recent showers. Highs are expected near 28–29°C (roughly 84–85°F), with lows around 22–24°C and minimal precipitation risk (under 10% in most runs). Recent developments reinforce this narrow range: showers and higher humidity on September 19 are giving way to clearing skies and drier northeast flow, preventing both strong warming and significant cooling. Historical late-September baselines for Shanghai average highs near 28°C, and current steering patterns show no incoming warm advection or cold outbreak that would push extremes. Minor model spread exists around exact peak timing and local station readings, but the bulk of guidance clusters tightly between 28–30°C, supporting trader emphasis on the 28°C and 29°C bins while assigning low probability to outliers below 27°C or above 30°C. Updated model runs and official briefings from Chinese meteorological sources will provide the next key signals before resolution.

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.
