January trade-offs

  • ↓Peak prices: accommodation 2–3× winter rates across all categories
  • ↓The Cape Doctor (south-easterly wind) blows strongest in summer — Clifton beaches can be windswept some afternoons
  • ↓January is peak domestic holiday season: Cape Town beaches, Chapman's Peak, and the Waterfront very crowded

September trade-offs

  • ↓Rain still possible in early September; the transition from winter to spring is gradual
  • ↓Sea still cool (15°C) — swimming in the Atlantic requires fortitude
  • ↓Some spring wind days on the Atlantic seaboard as the SE begins to strengthen for summer
