Cape Town's climate data reveals a fascinating pattern: it's one of the few Southern Hemisphere cities with a true Mediterranean climate. I was there in January (their summer) expecting tropical heat — instead got dry, windy, 26°C days perfect for wine country visits. The data shows December-February as ideal, but watch for the 'Cape Doctor' — a strong southeast wind that can disrupt plans. Winter (June-August) is wet and cool, but the whale watching peaks in July.
