The Lowdown
Okay folks, here’s the deal. We’ve got one spot on the table – Whale Rock. And I gotta be straight with you, it’s a tricky stretch ahead. We start off with a bit of size, but it’s pretty ragged and the conditions are fighting us. Let’s walk through it day by day.
From the get-go, Sunday the 23rd, there’s some swell coming in but the wind is a cross-breeze and the ocean’s getting thumped by 1868 units of combined swell energy. That’s a powerful, messy mix. Not one to get excited about. The afternoon drops off a fair bit too.
Monday the 24th morning brings a window of glass. The swell’s tiny though – only 0.7m out of the SSW. A pretty weak pulse, but clean. If you’ve got a longboard, this might be a quiet, glassy session before the flat spell. The afternoon shrinks further. Tuesday the 25th sees a longer period groundswell – 15 to 17 seconds – but the winds are cross and the energy numbers climb back up. The look’s still marginal.
Then Wednesday the 26th, things amp up – we get a solid 2.0m early, building to a 3.0m Southerly pulse by the afternoon with 17-second periods and the energy spikes to 5733. That’s a lot of power. But the wind turns cross-onshore, so the face will be lumpy and hard to handle. This is expert territory at that size, especially on a reef. It’s big and it’s not clean. Not sure it’s worth the risk unless you’re pulling into heavy, bumpy stuff.
Thursday the 27th is a write-off. Strong onshore winds – up to 45 km/h – and continuing swell. The ocean’s proper messy. Best to leave it.
From Friday the 28th right through to Tuesday the 3rd of September, we’re looking at a solid stretch of poor-to-marginal conditions. Swells drop under 1.5m, mostly cross-onshore winds, and weak energy numbers. There are a couple of clean windows – like Thursday morning the 3rd with light offshore cross-off wind and a small SSW groundswell – but it’s tiny (0.6m). You’d be scratching for runners.
Now, the only real highlight in all this comes Saturday the 5th of September. That morning looks glassy, the combo energy bumps up to 144, and we get a clean, small waist-high wave from the SSW. It’s not huge but it could be fun if you’ve got a fish or a longboard. That afternoon, the swell suddenly jumps to 2.3m from the SSE with 8-second period and 1144 energy, but the wind swings cross and it’s got chop. That’s the best of a tough period, and it’s still a session for the keen crew.
Best bet is the glassy morning on Saturday the 5th – small but clean. The standout bigger swell day (Wednesday 26th) is let down by lumpy onshore winds, so the quality’s blown.
Water temp sits at 21° in the first sessions, which is about normal for this time of year, so no surprises there.
Whale Rock itself is an advanced reef break, inconsistent and exposed, and it likes a Southerly direction. It can get a crowd sometimes. Over the coming weeks, expect a lot of flat or blown-out days between a few brief moments of clean surf.
Stay loose, keep an eye on the wind shifts.

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.
