Scuba diving in the Western Cape province of South Africa is possible year-round. The area generally has a Mediterranean climate with hot summers and rainy winters. Expect cooler temperatures during the winter season (June-August). However, the southern coast is much calmer and more accessible during these cooler months. On the other hand, the Atlantic coast becomes inaccessible during the winter months. As a rule of thumb, the season in which you visit will determine where you dive. Water temperatures average between 55 and 63°F (13 and 17°C). If you are looking for a thrill and the possibility of seeing something big, then diving in Western Cape is the right choice for you.
