The Lowdown
Alright, let’s get into it. First off, the water’s sitting at 70°, which is dead average for this time of year. No weird warm or cold blips to worry about. You’re not gonna need a hood, but it’s not warm either.
So, here’s the deal for the next couple of weeks. Honestly, the forecast is a bit of a grind. We’ve got a lot of energy in the water, but the wind is going to be fighting us for most of it. The first real window of surf kicks off Sunday morning, the 9th. The swell is coming in at 4ft from the SSW with a 14-second period. It’s got some push to it, moderate energy at 568, but it’s an inconsistent spot, so the lulls could be long. Wind is a cross-off from the SW, which will help keep it semi-clean. It’s not going to be epic, but it’s something to get wet for.
The rest of that first week is pretty ordinary. We bounce around between onshore and cross-onshore winds, with a bit of chop. The swell jumps up on Monday with a 10ft pulse from the SSE, but that short 8-second period and onshore wind make it a messy, close-out mess. Not worth your time. The next few days are similar, with a mix of onshore winds and a few clean windows, but nothing that really stands out. Most of the scores are in the marginal-to-poor range, so I’d be picking my sessions carefully.
The first real standout shows up on Sunday the 16th. We’ve got a 7ft swell from the E with an 11-second period, and it’s pushing a solid 957 in the energy department. The wind is light from the ENE, so it’s got a chance to be halfway decent. It’s still a cross-on, but light enough to keep the surface clean. This is probably the pick of the first week. Monday the 17th is similar, with 7ft and 6ft from the E, but the wind is a touch stronger. Still, those are your best bets for a proper session.
Then we hit a dry spell. From the 18th through the 20th, there’s nothing doing. The swell is small, the wind is either calm or howling, and the whole thing just looks flat and uninspiring. It’s a good time to do maintenance on your boards.
Now, for the second week, things get a bit more interesting, but it’s a real mixed bag. The 21st brings in a building SW groundswell, but the wind is howling onshore from the ENE, so it’s going to be a washing machine. Then we get a big pulse on the 22nd. We’re looking at a solid 10ft from the S with a 14-second period, and the energy is cranking at 3110. That’s a strong swell. But the wind is a cross from the NE, and that’s a tricky one. It might have some shape, but it’s going to be raw. This is pushing into expert territory, and with the currents and the power, it’s not a day for beginners. The period is long too, which at a reef like this could be proper. But the wind is the issue.
After that, the end of the run is a bit of a flop. The 23rd and 24th are smaller, but the wind stays onshore. The 24th does have a long-period SSW swell (17-second period) coming through, but it’s around 5-6ft and the NE wind is going to put a bump on it. It’s a tease, really.
So, if you’re looking for the best on offer, your top pick is probably Sunday the 16th. It’s got the size, the energy, and the lightest wind of the whole run. Monday the 17th is a close second. The big pulse on the 22nd is there for the brave and the experienced, but it’s a wild card with the wind. The rest is just making the most of it.
For a spot like this, being inconsistent is part of the game. It’s not a place that fires every day, so you have to be ready to move when the windows open. Right now, those windows are few and far between, but they’re there.

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.
