Forecast models from agencies like the South African Weather Service show a tight cluster of possible daily maximums in Cape Town around 21–23°C for August 28, reflecting modest uncertainty in the timing of a weak frontal system and variable cloud cover over the Cape Peninsula. Winter baseline temperatures typically peak near 18–20°C under prevailing westerlies, but recent drier conditions and potential subsidence have nudged trader-implied odds toward slightly milder outcomes. Key variables differentiating the 21°C versus 23°C bins include local wind shifts around Table Mountain and the degree of afternoon clearing, which ensemble runs continue to resolve differently. Daily updated guidance through the weekend will likely narrow these closely matched probabilities before resolution.
