Current forecasts for Cape Town on August 28 indicate a mild winter day with highs likely in the 18–24°C range, driven primarily by variable cloud cover and shifting winds under a moderate pressure gradient. Recent model runs show potential afternoon warming from northerly or northwesterly flow, which can advect milder air, contrasted with increasing southerly winds and higher cloud fractions that limit solar insolation and cap temperatures. Official South African Weather Service guidance and global ensembles highlight this narrow spread, with historical August maxima averaging near 17°C but recent observations trending warmer. The closely matched market odds around 21–23°C reflect genuine uncertainty in peak timing, local urban heat effects, and evolving model consensus ahead of updated runs.

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 28 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.Current forecasts for Cape Town on August 28 indicate a mild winter day with highs likely in the 18–24°C range, driven primarily by variable cloud cover and shifting winds under a moderate pressure gradient.
