Diaz Beach

Mossel Bay, South Africa
🌀Strong rips🦈Sharks

Diaz Beach is Mossel Bay's long sandy stretch, breaking directly in front of the old Dias hotel with lefts and rights spread across kilometers of shifting banks. Named for Bartolomeu Dias, who landed in this bay in 1488, it is one of the Southern Cape's best places to learn: sandy bottom, manageable peaks and a town that claims one of the mildest year-round climates anywhere. It needs a decent southeast swell to get going inside the protected bay, and the rips deserve respect when it does.

Frequently Asked Questions

What tide is best at Diaz Beach?

The Diaz Beach profile does not specify a preferred tide stage. That does not mean tide has no effect: check local conditions alongside swell and wind.

What wind direction is offshore at Diaz Beach?

The Diaz Beach profile uses wind from WNW (292°) as its preferred direction, with an offshore range of 270° to 330°. Wind speed matters too: light winds outside that range can still produce surfable conditions, while strong offshore winds can make takeoffs difficult.

What swell size and direction work best at Diaz Beach?

The Diaz Beach scoring profile favors swell from SE (100° to 180°), a swell-height range of 1m to 2.5m, and a reference period of 12s. These are model inputs, not guaranteed breaking-wave heights or a promise that the surf will suit every ability.

When is the best time of year to surf Diaz Beach?

The main season at Diaz Beach is Apr-Sep. Winter is most consistent; the bay blocks a lot of swell, so it is often too small.

How do I get to Diaz Beach?

The spot profile lists GRJ as a nearby airport. The estimated road transfer is 30 minutes.

What kind of wave is Diaz Beach?

Diaz Beach is a beach break, a peak with lefts and rights over a sand bottom. Difficulty is rated 3/10.
