Here, we look at Johannesburg’s weather on a seasonal and monthly basis to help you plan what to pack and what activities to consider for your visit to Johannesburg.
Johannesburg Weather in Autumn or Fall: March, April, May
Many people love visiting Johannesburg in autumn because the weather is warm and sunny but not as hot as in the summer. The autumn weather is warm enough to explore the sights and sounds of Johannesburg.

During Autumn, Johannesburg’s thundershowers decrease, and there may be an occasional brief burst of rain with little effect on the weather.
During Autumn I usually wear a short-sleeved shirt and long pants. I may also carry a light sweater or jacket in case it becomes cold in the evening. Although open-toed shoes will be fine during the day, you will need closed shoes to keep your feet warm as night falls. For men, the same types of clothing (short-sleeved shirt, long pants, light sweater and closed-toed shoes) will be helpful for an autumn visit to Johannesburg.
As autumn starts, you can comfortably wear a dress or skirt during Autumn with your light sweater at night. However, towards the end of May, your legs may find the weather too chilly when you wear a skirt or dress.
