**Trader consensus centers on 22–24°C for Cape Town’s August 27 maximum, reflecting tight model spread in short-range forecasts amid typical late-winter variability.** South African Weather Service and global guidance indicate fine conditions with moderate southerly to south-easterly flow, yielding daytime highs near or slightly above the seasonal 17–18°C average. Key differentiating factors include the strength and position of the South Atlantic high, which modulates onshore flow from the cooler Benguela Current, versus any transient northerly component or reduced cloud cover that could allow greater insolation and push readings toward 24–25°C. Recent model runs show minor disagreements on exact wind backing and boundary-layer mixing, creating the observed clustering around the 22–24°C outcomes while limiting support for extremes below 20°C or above 25°C. Updated NWP guidance and SAWS briefings over the next 24–48 hours will likely narrow this range ahead of resolution.

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.
