Current meteorological forecasts from models such as GFS indicate a nighttime minimum near 12°C for Cape Town on October 15, supported by observed conditions including persistent cloud cover, northerly winds around 15-20 mph, and dew points near 10-12°C that limit radiative cooling. This aligns with typical spring climatology for the region, where October lows average 12-14°C under similar synoptic patterns. Trader consensus at 93.5% implied probability for 12°C reflects high confidence in these official guidance products, though modest uncertainty remains from potential model shifts in cloud thickness or wind direction that could allow temperatures to dip to 11°C or hold at 13°C. Updated short-term forecasts and real-time observations through the overnight period represent the primary near-term catalysts.
