Christmas Weather
December marks the beginning of the summer season in Cape Town, South Africa, and the days are glorious with little precipitation and plenty of bright sunlight.
Located on South Africa’s southern coast, the weather in Cape Town remains temperate all year long, but winter can be rainy, making December and the other summer months a much better time for visitors who want to be outdoors. It is easy to see why the rising temperatures and dry days that characterise December make it one of the most popular times to visit this resort.

Overall, Cape Town is a wonderful December destination. The holiday spirit is in full swing, and because it is located in the southern hemisphere December is the sunniest month of the year in Cape Town, and also has the longest days. These factors mean you can expect an average 11 hours of bright sunlight daily. For visitors from Europe and other places in the northern hemisphere, Cape Town is a great place to find some sun.
Rising temperatures in December beckon visitors and locals alike to the outdoors.
