Latest meteorological guidance from the South African Weather Service and global models shows a transitional pattern over the Western Cape, with a moderating Atlantic high and weakening onshore flow potentially allowing daytime maxima in Cape Town to reach the mid-20s °C on August 13 amid typical August variability. Trader emphasis on 27 °C reflects model consensus around seasonal warming episodes, while lower probabilities for 28–29 °C account for possible residual cool advection or increased cloud cover from lingering frontal activity. Key variables include exact steering of the subtropical ridge, sea-surface temperatures along the Benguela Current, and afternoon mixing depth; historical analogs indicate August highs rarely exceed 22 °C without strong subsidence. Updated model runs and SAWS briefings over the next 48 hours will refine these probabilities ahead of market resolution.
