Recent global model runs, including GFS guidance, point to a daytime high near 19–20 °C in Cape Town on October 15 under partly cloudy skies and fresh northwesterly flow. This pattern favors modest warming from the Benguela Current’s cool marine layer while limiting full insolation. Differences among the tightly bunched 21–23 °C outcomes hinge on small variations in low-cloud persistence, boundary-layer mixing depth, and exact wind speeds that modulate onshore advection of cooler marine air. Historical October maxima average near 20–22 °C, so traders are weighting the potential for a brief ridge-induced spike versus continued cloud suppression. Updated SAWS and ensemble guidance later today will likely refine the precise peak before resolution.
