**Latest ensemble forecasts from the South African Weather Service and global models point to a mild winter day with peak temperatures most likely in the low-to-mid 20s Celsius, driven by weak high pressure and limited cloud cover over the Western Cape.** Historical August averages near 17–19°C provide context, yet recent model runs show a modest warm anomaly from light northerly flow that can enhance daytime heating despite the cold Benguela Current influence. Low precipitation odds and variable wind shifts introduce spread across guidance, with some solutions reaching 25°C while others cap nearer 22°C, explaining the tight clustering of market-implied probabilities around 23°C and 24°C. Updated SAWS briefings and afternoon model runs in the next 48 hours will clarify resolution thresholds for this single-day maximum.

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 27 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.**Latest ensemble forecasts from the South African Weather Service and global models point to a mild winter day with peak temperatures most likely in the low-to-mid 20s Celsius, driven by weak high pressure and limited cloud cover over the Western Cape.** Historical August averages near 17–19°C provide context, yet recent model runs show a modest warm anomaly from light northerly flow that can enhance daytime heating despite the cold Benguela Current influence.
