The Lowdown
Alright folks, Rusty here. Let's take a long, hard look at what Whale Rock has in store for us over the next couple of weeks. I gotta be straight with you from the get-go – this stretch is gonna test your patience.
The overall pattern is dominated by persistent, messy wind. A lot of the time, it’s coming from the east or northeast, which is cross-onshore for this spot, chopping up the line-up and making things feel like a battle. For a reef break that demands respect, that’s a tough hand to be dealt. The water's also sitting at a very unusual 62° – that's nearly 7° colder than normal for this time of year up at Whale Rock, so you'll want a good, thick wetsuit. Don't leave your hood at home.
For the first many days, it's honestly a write-off. From the 12th right through the 19th of September, the winds are just nasty. We see a lot of "poor surf conditions" in the cards. Even when there’s size, like a 10ft swell on Monday the 14th with a combined energy reading over 2000, it's accompanied by a fresh 22 mph cross-onshore. That’s lumpy, messy, and frankly, dangerous. For a few days around the 15th and 16th, the swell drops off to under 3ft with weak energy, so there’s nothing doing. It starts to get some push again around the 17th, but again, the wind angles are all wrong.
We do have one brief window, and it’s the only thing on this forecast that gets me talking. Look towards Tuesday the 22nd of September. That afternoon session sees a clean 8ft swell from the east (energy is a solid 1476), but more importantly, the wind is forecast to swing light and offshore from the southeast at just 9 mph. For Whale Rock, an east swell is okay, not perfect, but that offshore wind will clean everything right up. The period is a decent 11 seconds, hinting at some good groundswell lines. This would be the standout for the whole 16-day run – it's the only time the wind plays ball with any real size.
But don't get too excited. The morning of the 23rd is back to a fresh 19 mph cross-on from the northeast, ruining it. Then, on the 25th of September, we see another possible window. Friday afternoon shows a 6ft east swell (809 energy) with a moderate cross-offshore breeze from the southwest. That’s a better angle than most and could offer some clean-ish, lined-up walls. After that, the wind swings back on for the weekend.
To be brutally honest, this is a lean patch for Whale Rock. The one truly promising moment is on the afternoon of Tuesday the 22nd, and maybe the afternoon of the 25th for a backup surf. For everything else, you’d be fighting the wind more than the wave. It’s an exposed spot, and right now, it's feeling the full force of the breeze.
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.
