Recent forecasts indicate a frontal system approaching Cape Town, with rain likely on September 3 accompanied by strengthening southeasterly winds, which traders weigh against typical spring minima near 10–11°C. Cloud cover from precipitation reduces nocturnal radiative cooling, while wind-driven mixing and maritime influence from the Benguela Current limit sharp drops, supporting the clustered probabilities around 10–14°C. Model spread on exact timing and intensity of the system creates the tight contest between sub-8°C outcomes and milder readings above 16°C, with new guidance from regional and global ensembles expected to refine resolution criteria before the 24-hour minimum is recorded.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Cape Town International Airport Station in degrees Celsius on 3 Sep '26.
The resolution source for this market will be information from NOAA, specifically the lowest 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 indicate a frontal system approaching Cape Town, with rain likely on September 3 accompanied by strengthening southeasterly winds, which traders weigh against typical spring minima near 10–11°C.
