**Recent forecasts for Cape Town on August 30 show notable spread in expected overnight minimums, with model outputs clustering around 10–12°C but some guidance dipping toward 7°C or holding near 13°C, creating the tight market spread across 10–11°C and nearby buckets.** Clear or mostly clear skies under a building high-pressure ridge, combined with moderate south to southeasterly winds (10–15 km/h), favor radiative cooling after daytime highs near 16°C. Dew points near 5–7°C support efficient heat loss once the sun sets, while limited cloud cover overnight reduces downward longwave radiation. South African Weather Service and international guidance highlight a transition to drier, clearer conditions following earlier showers, with the primary uncertainty stemming from subtle differences in wind speed, boundary-layer mixing, and exact timing of any residual moisture. Historical August minima in Cape Town often range 5–12°C, placing the current setup near or slightly above average; the 16°C+ outcome remains possible only if stronger mixing or delayed clearing occurs. Updated model runs and official minimum observations will resolve the market.
