Recent forecast model consensus points to a daily maximum of 23–25°C in Cape Town on September 24, reflecting above-average spring conditions driven by a building high-pressure ridge and southwesterly flow off the cooler Atlantic. Variable cloud cover and moderate winds are limiting stronger daytime heating, while clear intervals in some runs allow brief warming toward the mid-20s. Historical September maxima average near 19°C, so current guidance implies a modest warm anomaly. Updated runs from global and regional models, along with official South African Weather Service briefings, will clarify whether thicker marine layer stratus or clearer skies ultimately determine the peak reading.

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.
