Recent forecasts for Cape Town's maximum temperature on September 20 show a tight cluster of outcomes centered on 25–27°C, reflecting model consensus amid clear skies, light southerly winds, and strengthening insolation during early Southern Hemisphere spring. High-pressure dominance has suppressed cloud cover and precipitation, allowing daytime heating to build, while southeast winds provide moderate cooling that prevents extremes. Global models like GFS and ECMWF diverge slightly on boundary-layer mixing and exact wind speeds, producing the observed spread between 24°C and 28°C scenarios. Historical September maxima average near 18–20°C, but this season's +2°C anomaly and stable conditions support the market's emphasis on the upper end of typical ranges, with new model runs and observational updates expected to refine probabilities before resolution.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Cape Town International Airport Station in degrees Celsius on 20 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=fact
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.Recent forecasts for Cape Town's maximum temperature on September 20 show a tight cluster of outcomes centered on 25–27°C, reflecting model consensus amid clear skies, light southerly winds, and strengthening insolation during early Southern Hemisphere spring.
