Current forecast models from sources like GFS and ECMWF indicate stable high-pressure conditions and clear skies over Cape Town on September 30, with light easterly winds limiting radiative cooling and supporting overnight lows near 14–16°C. This aligns with the market-implied odds favoring 15°C and 16°C options, as recent model runs show minimal influence from cooler Atlantic air or frontal systems typical for late spring. Historical September minima average around 10°C, yet the absence of significant cooling events in the past week has tempered trader expectations for colder outcomes like 8°C or below, despite its leading 47% implied probability reflecting residual model uncertainty. Updated briefings from regional meteorological agencies ahead of resolution could further refine these probabilities.
