Recent cold fronts crossing the Western Cape have kept Cape Town under cooler, post-frontal high pressure, producing model consensus for daytime maxima near the seasonal 18°C average yet with enough variability in cloud cover and northerly flow to support trader clustering around 22–23°C. Official South African Weather Service guidance highlights lingering onshore winds and scattered moisture that cap rapid warming, while ensemble spreads from global models show modest potential for brief clearing that could push readings 2–4°C higher. This tight distribution of implied probabilities captures the narrow window between typical winter stabilization and modest recovery heating before the next system arrives.
