Recent forecasts from multiple models indicate a high of 16–19°C in Cape Town on August 29, aligning with the closely bunched market odds around 17–18°C. A strengthening southerly flow ahead of a weak cold front is advecting cooler maritime air from the South Atlantic, while extensive low- to mid-level cloud cover and a 30–70% chance of light rain or drizzle limit daytime insolation and surface heating. These conditions follow milder northerly flow on the 27th–28th that produced highs near 20–25°C. Ensemble guidance shows modest spread in peak values depending on exact frontal timing and cloud breaks, with official agencies such as the South African Weather Service expected to issue updated guidance in the next 24–48 hours that could refine the maximum temperature range.

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 29 Aug '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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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 from multiple models indicate a high of 16–19°C in Cape Town on August 29, aligning with the closely bunched market odds around 17–18°C.
