It's a great time for couples to enjoy wine tasting without the summer crowds.Autumn, from September to October, offers similarly agreeable weather, with temperatures between 15°C and 28°C. This period coincides with the grape harvest, providing a unique opportunity to experience local wine festivals and events.
