Many travel experts believe that September is actually the best time to visit South Africa, primarily because wildlife start emerging from their winter hideouts with the start of spring. Along with this, there is also an improvement in weather conditions. There are a lot of reasons to check out South Africa in September. Let us go through a few of them below.

  • Safari magic: The start of spring and South African weather mean that the animals of Kruger National Park come out into the open seeking watering holes, making this an ideal time to go on safari tours.
  • Beach paradise: If you are heading towards Durban and the coastal areas of the Indian Ocean, you can expect beautifully warm and dry conditions. This makes September a great month to enjoy a relaxing stay on the beach.
  • Whale-watching: September marks the start of the peak whale-watching season. Head down to Hermanus and the Western Cape to track their migratory pattern and see these magnificent giants in the wild.
  • Swim with sharks: If you want to swim with some of the oceans’ scariest inhabitants, September is the last month of the peak season. This is because cooler waters draw sharks to the shore to feed. Dive if you dare!

Where to go and what to do

Speaking of whale-watching, you might want to join the flood of locals and tourists alike and head down to Hermanus for the Hermanus Whale Festival. This event celebrates the start of their migration, and you can enjoy three days of parades, eco-friendly educational exhibits, music and culinary delights. This, together with spotting whales, makes for an unforgettable experience.

If you are planning on being in South Africa towards the end of September, specifically on September 24, you can enjoy Heritage Day, a national holiday. This is also known as National Braai Day and offers a chance to try South African classics on the barbecue like chakalaka and pap. Events are held all across the country on this day, so you are bound to have an amazing time regardless of where in South Africa you find yourself.

The weather in South Africa in September is ideal for a hiking trip on the famous Table Mountain. Although the peak hiking season begins in November, when South Africa is at its driest, cooler temperatures make September a more enjoyable time to go on a hike — just come prepared for any impromptu rainfall!

If you are coming to South Africa for safaris, this is a great time to do it as warm weather means that animals queue around watering holes. Great spots for an ultimate safari experience include Kruger, Addo Elephant Park and Marakele.

All in all, September is a great month to visit South Africa. Whether you are heading inland to check out the wildlife at one of the many national parks, traveling to coastal areas for whale-watching, or are looking forward to kicking back on a sandy stretch, there is something to suit everyone during this time of year.
