What to pack
For a trip to Йоханнесбург in summer (November to February), pack light, breathable clothing for daytime temperatures around +25 °C, but include a light jacket for cooler evenings. A compact umbrella or raincoat is essential, as summer showers are common. Comfortable walking shoes are a must for exploring the city’s outdoor attractions.
Winter visitors (June to August) should bring layers—warm clothing for chilly mornings and evenings, but lighter options for midday when temperatures rise to +17 °C. A scarf and gloves may be useful for early mornings, especially in July, when nights drop to +4 °C. Sunglasses are still a good idea, as sunny days are frequent.
In the shoulder seasons (March to May and September to October), Йоханнесбург’s weather is mild, so versatile layers work best. A mix of short- and long-sleeved shirts, along with a light sweater, will cover most conditions. If visiting in April or October, a light rain jacket is a good precaution, though rain is less likely than in summer.
