Current forecast models from multiple sources project a minimum temperature of 11–13°C for Cape Town on September 28, 2026, under southeasterly winds of 15–25 km/h and mostly clear to partly cloudy skies associated with the South Atlantic subtropical high. This spring pattern typically produces overnight radiative cooling moderated by the Benguela Current and orographic effects from Table Mountain, keeping lows above the seasonal average minimum near 10°C. Model consensus shows limited spread, though small shifts in wind strength or cloud cover could alter the exact low by 1–2°C. Official South African Weather Service updates and final 24-hour observations will determine resolution, with traders weighing these factors against historical September variability.
