The Lowdown
Alright, folks, Rusty here. We’ve got a long look ahead at our local spot, Whale Rock, and it’s a bit of a mixed bag. The pickings are slim for a while, but there are a couple of windows that will get the blood pumping.
Right now, we’re looking at a slow start. The first couple of days are honestly not worth paddling out for. The swell is messy, and the winds are all over the shop. Thursday the 20th has a bit of 6ft swell, but it’s short-period, wind-affected junk that’s more frustration than fun. We’ve got a bit of a gap here with no real quality on offer through to the weekend.
The weekend itself is a write-off. Saturday the 22nd gets absolutely thumped by a strong cross-shore near-gale, blowing 31 mph into a lumpy 12ft mess. That’s not for paddling; that’s for the kite crew if anything. Sunday follows with a big but unruly 8ft swell under a cross breeze—still too raw to get excited about.
Keep your eyes on Monday morning the 24th. That’s our first proper highlight. We’ve got clean 4ft swell rolling in from the south under glassy, dead-calm conditions. The water temp is about average for this time of year, so it won’t feel out of the ordinary. The energy is moderate (607), and for a reef break like Whale Rock, those clean conditions will make every wave count. If you can sneak off for a Monday session, that’s the one to chase.
Then, Tuesday morning the 25th serves up what looks like the standout of this whole forecast. The swell pushes up to a solid 5ft from the SSW, but the wind is a clean offshore breeze (cross-off) from the southwest. The period stretches out to a long 15 seconds, meaning that groundswell energy is packing a punch with 1093 units of energy. This is proper, powerful surf for experienced surfers. Expect long, lined-up waves at Whale Rock, but the crowd might be an issue, as it’s a spot that can get busy when the surf’s this good. This is the one to circle on the calendar.
After that, things get messy again. The rest of that week and into September is mostly a write-off with strong onshore winds, lumpy conditions, and poor surf quality. We do get a brief glimmer on Sunday afternoon the 30th—another glassy session with 5ft of clean south swell (693 energy). It’s a very late call, but keep it in the back of your mind if you’re desperate for a wave when the wind dies off.
That’s the long story, short. A couple of gems buried in a lot of rubbish. Stay patient, be ready for that Monday morning glass and that Tuesday offshore session.
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.
