Recent passage of a cold front over the Western Cape has set up post-frontal warming across Cape Town on August 13, with South African Weather Service and other models projecting a daytime maximum of 25–28 °C under mostly fine conditions and light-to-moderate easterly to north-westerly winds. Clear skies promote strong solar heating while the preceding frontal clearing reduces cloud cover and moisture, elevating temperatures above typical mid-August climatology near 18–20 °C. The narrow spread between the leading 27 °C and 28 °C outcomes reflects minor model differences in the timing of the wind shift, boundary-layer mixing, and peak insolation rates, which can shift the observed maximum by 1 °C at the official measurement site. Traders are weighting these near-term observational and forecast updates most heavily as the day progresses.
