“When is the best time to dive?”

The answer isn’t simple because Aliwal Shoal offers two completely different worlds depending on the season.

Unlike tropical coral reefs that stay largely the same, the KwaZulu-Natal coast is dynamic. Here is how to choose your travel dates based on what you want to see.

Summer (December – May)

The Season of Giants. If you love warm water (24°C – 26°C) and big predators, this is your season. Summer brings the warm Mozambique current, and with it, the Tiger Sharks. These striped giants are most active in the warmer months. You can also expect to see schools of Scalloped Hammerheads passing through the blue.

Visibility: Generally good, though river runoff can occur after heavy rains.

Best for: Baited Shark Dives and warm-water reef drifting.

Winter (June – November)

The Raggie Migration Winter is arguably the most exciting time on the Shoal. The water cools down (19°C – 21°C), but the visibility often opens up to crystal clear conditions.

The Raggies: This is the mating season for the Spotted Ragged Tooth Shark. Hundreds of them congregate in Raggies Cave and Cathedral, offering incredible photo opportunities.

The Sardine Run: In June and July, the “Greatest Shoal on Earth” passes our coastline, bringing whales, dolphins, and chaos to the ocean.

The Verdict?

Come in winter for Raggies and clear water. Come in summer for Tiger Sharks and wetsuit-free warmth. Whatever you choose, ScubaCo launches boats daily.
