Hoedspruit is a part of Limpopo. With almost all year-round sunshine, it can get rather hot in the summer months. From October to March, the weather touches 27 degree Celsius. However, you can expect temperatures to soar up to 30 degree Celsius during this time too.
You can also visit Johannesburg in spring when the skies are clear and hot. So, the best time to visit Hoedspruit would definitely be June to August. The city is lively and there is a chance you get to see all the attractions!
