Recent model consensus from sources including ECMWF and GFS points to clear skies and moderate southerly winds maintaining overnight lows near 10–12°C in Cape Town on August 24, with the primary catalyst being a stable high-pressure ridge limiting cold-air advection from the interior. Radiative cooling under minimal cloud cover will drive the daily minimum around dawn, modulated by boundary-layer mixing from 10–15 km/h winds and dew points near 9–11°C that curb further drops. Historical August climatology shows typical minima of 8–11°C at the airport, yet current ensemble spreads reflect uncertainty from local urban heat effects versus coastal influences, keeping trader-implied odds tightly clustered between sub-8°C and 11–12°C outcomes. Updated runs ahead of resolution will refine thresholds.
