Best Time to Visit
The best time to visit Johannesburg is during the spring (September to November) and autumn (March to May) when temperatures are mild and rainfall is moderate. However, each season offers unique experiences:
Summer (December-February) brings warm temperatures and frequent afternoon thunderstorms. While this is the peak growing season with lush landscapes, outdoor activities should be planned for mornings to avoid afternoon rains. The thunderstorms are typically short-lived but intense.
Autumn (March-May) offers pleasant temperatures and decreasing rainfall. This is an excellent time for outdoor activities and sightseeing, with comfortable temperatures and clear skies. The changing colors of the trees add to the city's beauty.
Winter (June-August) is cool and dry with cold nights but sunny days. This is the best time for outdoor activities and wildlife viewing, as the dry conditions make animals easier to spot. The clear winter skies offer excellent visibility.
Spring (September-November) sees warming temperatures and the start of the rainy season. This is when the city comes alive with jacaranda trees in bloom, creating stunning purple canopies throughout the streets. Morning activities are recommended as afternoon thunderstorms become more frequent.
