Recent GFS-based forecasts for Cape Town indicate an expected overnight minimum near 13–14°C on October 1, driven by a shift to northwesterly winds and increasing cloud cover that moderates radiative cooling. Historical averages for early October hover around 12–13°C lows, but current model consensus shows modest warming from prevailing spring patterns, with daytime highs projected at 21–23°C. The near-even market split between 10°C-or-below and 20°C-or-higher outcomes reflects uncertainty in final model runs, potential wind direction changes, and cloud thickness that could alter the minimum by several degrees. Updated forecasts from the South African Weather Service and ensemble guidance ahead of October 1 will likely clarify resolution thresholds tied to official observations.
