Recent forecasts from multiple models show Cape Town's September 24 high temperature likely ranging 23–26°C under mostly cloudy to partly sunny conditions, with southwesterly winds and moderate humidity limiting extreme warming. Trader sentiment favors the 27°C-or-higher outcome at 36% because current spring patterns and a warmer-than-average September 22 (highs near 29–30°C) support potential for a stronger high-pressure ridge or reduced marine influence that could push afternoon readings higher. Official South African Weather Service guidance and updated GFS/ECMWF runs expected in the next 24–48 hours will clarify whether sea breezes or cloud cover cap the peak below 25°C, where combined probabilities for 24–26°C already exceed 55%. Historical September maxima average near 19°C, underscoring the current anomaly driving market positioning.

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.
