The Lowdown
G’day, Rusty here. Let’s talk about Whale Rock. It’s a tricky reef setup for advanced crew only, and it’s inconsistent, so you gotta pick your moments. Water temp is about average for this time of year, nothing wild.
The first good window kicks off Friday morning, August 21st. We’ve got some clouds, a light onshore breeze from the SSE, and a clean 5ft swell from the SSW at 13 seconds. Combined energy is moderate (653). It’s small, but that long period groundswell will give it shape. The cross-on wind is a bit of a buzzkill, but it’s light, so worth a paddle if you’re keen.
The pattern dips after that, with a blustery Saturday afternoon—10ft of SSW swell but with a short 8-second period, and a near gale cross-off wind. That’s messy and only for the hardcore. Sunday morning offers 8ft at 10 seconds, but with a moderate cross-shore chop. Still, it’s a step up in size.
The standout moment comes Monday morning, August 24th. Glassy conditions, light air, and 3ft of SSW swell with a 14-second period. Combined energy is moderate (400). It’s small, but that glassy surface and long period are a dream for a reef break. The crowd could be on it, though, so get there early.
Tuesday, August 25th, has a 5ft SSW swell at 16 seconds—very long period—and a light cross-on from the SSE. Combined energy is moderate (919). The period is so long it might make the reef line up beautifully, but it could also be a bit straight. Worth a look.
From Wednesday morning, August 26th, the wind builds from the NE, and the swell switches to S direction. The quality drops off fast with fresh cross-onshore winds and lumpy seas. By Thursday and Friday, it’s poor—strong winds, messy waves. The combo of squally conditions and short-period swell (8 seconds) on the 31st of August and 1st of September is not for paddling. This stretch looks more like a kite-surfing setup than a paddle session.
We get a glimmer early on Thursday, September 3rd, with a 4ft SW swell at 13 seconds and a clean cross-off breeze from the SW. Combined energy is moderate (707). It’s clean, but the wind is strong, making it a marginal call.
The real highlight, though, is Friday morning, September 4th. A solid 10ft SSW swell at 16 seconds, with a light cross-on from the SE. Combined energy is strong (5301). That’s a big, long-period groundswell with a light breeze. It’s over 8ft, so only for experts, and the reef might handle that long period better than a beach break. The crowd could be there, but this is the best on offer in the whole 16-day run. The afternoon drops off with a shorter period, so hit the morning session.
After that, Saturday the 5th is a write-off with fresh cross-onshore winds and lumpy conditions.
There’s a long gap of poor surf from the 26th of August through to the 2nd of September, with only a few marginal windows. The forecast can change, but right now, that 4th of September is the one to circle.
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.
