The Lowdown

Alright, this is Rusty, and I’ve got the scoop for Whale Rock.

First thing you need to know: this spot is a fickle one. It’s an exposed reef break that needs the right swell direction and a whole lot of luck. Over the next 16 days, there’s nothing that’s really on fire. The water’s sitting at about 70°F which feels pretty normal for this time of year, nothing weird going on there.

We kick off on Monday, August 17, with a tiny 1ft SW groundswell and glassy conditions from a light easterly. It’s clean as a whistle, but honestly, there’s just no energy – combined swell energy is only 27. It’s a little heartbreaker because the conditions are perfect, but the ocean’s flat.

Tuesday the 18th sees a small increase, with 4ft of easterly swell and clean cross-offshore winds from the SW in the morning, but it’s a short-period windswell at 10 seconds and the energy is moderate (432). It’s surfable for someone who really wants to get wet, but nothing to write home about.

Wednesday the 19th and Thursday the 20th are pretty chopped up by wind. Thursday morning does see a bump to 5ft of SSW swell with clean cross-offshore wind, but the period is a short and weak 8 seconds. That afternoon, the swell jumps to 7ft from the SSW with a much nicer 14 second period, and the energy is strong (1591) – but the wind is onshore, making it bumpy. It’s big enough for stronger surfers but messy.

Friday the 21st through Saturday the 22nd is a write-off. Strong winds, lumpy conditions, and poor surf quality.

Now, here’s the closest thing to a standout in this whole run. On Sunday, August 23, we get a solid 5ft SSW groundswell rolling in at 12 seconds. The big news is the morning wind: offshore from the SE, glassy and clean. The energy is strong at 944. This is the window. The setup looks cleanest for those dawny sessions, but remember, Whale Rock is inconsistent and rarely breaks this well, so if you’re there, you’re in for a treat. Crowds sometimes show up here, so you might have a few friends.

Monday the 24th keeps the momentum with 6ft of SSW swell at 14 seconds and light cross-shore winds. The swell energy is very strong (1090) and the waves will have proper shape and power. It’s a solid option for intermediate to advanced surfers.

After that, the quality drops off a cliff. From Tuesday the 25th onward, winds get messy or the swell just fades. There’s a pulse of windswell on Wednesday the 26th (5ft from the ENE at a dreadful 6 seconds) but it’s howling onshore at 22 mph – that’s more of a kitesurfing day than a paddle day.

By the time we hit the end of August and into early September, the swell is small and weak, with cross-shore winds and poor conditions. There’s a small window on Sunday, August 30, with 4ft of SSE short-period swell, but it’s choppy.

So to sum it up: your only real shot at something decent is the weekend of August 23-24. That Sunday morning with the 5ft SSW groundswell and offshore wind is the pick of the bunch. The rest of the 16 days are either flat, blown out, or too messy to bother. Keep an eye on the charts, because this spot can turn on a dime, but for now, it’s mostly patience and a whole lot of waiting.

Rusty.

Information about the Whale Rock Surf forecast

The above surf forecast table for Whale Rock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Whale Rock can be found by selecting the local surf guide option on the grey menu. Our Whale Rock surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Whale Rock) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Whale Rock may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Whale Rock is 47 km (29 miles) from the city of Port Saint Johns. If you plan a holiday in Eastern Cape - Wild Coast, look for hotels and other accommodation in Port Saint Johns. Port Saint Johns has rooms for a wide range of budgets as well as car hire and transport links.
