Recent forecasts from multiple models indicate Cape Town's overnight low on October 8 will likely range from 9–12°C under partly cloudy skies with light westerly to northwesterly winds, consistent with spring climatology moderated by the cool Benguela Current. Radiational cooling under clearer intervals could push the minimum lower than daytime averages near 17–19°C, while increased cloud cover or stronger onshore flow may limit the drop. Model consensus shows limited spread, but small shifts in wind direction, humidity, or frontal passage introduce uncertainty around the exact threshold. Official South African Weather Service observations will determine resolution, with traders pricing the 5°C-or-below outcome highest amid awareness of potential model underestimation during transitional seasons.
