Recent forecasts from South African Weather Service models and global ensembles point to a cool winter day in Cape Town on July 4, with highest temperatures most likely in the 16–18°C range amid a lingering upper-air trough and moderate Atlantic onshore flow. These conditions limit daytime heating through increased cloud cover and marine air advection, consistent with July climatology where average maxima reach 15–17°C. Key variables differentiating narrow outcome bins include exact cloud timing, wind shifts from southerly to northeasterly, and any weak frontal passage that could add or subtract 1–2°C. Updated model runs over the next 48 hours will refine these details ahead of market resolution.
