Forecasts for Cape Town’s maximum temperature on August 28 center on 17–22 °C amid mixed model guidance and transitional synoptic patterns. Recent high-pressure ridging has produced above-average daytime warmth earlier in the month, yet an approaching cold front and increasing south-westerly flow are expected to enhance cloud cover and marine-layer influence, limiting insolation and peak heating. Ensemble spreads from global and regional models reflect this sensitivity to boundary-layer moisture and wind direction, keeping the distribution of possible daily maxima broad. Official updates from the South African Weather Service and short-range model runs over the next 48 hours will likely narrow the range and determine which temperature bin resolves the market.

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.
