The Lowdown
Right, pull up a chair, grab a coffee. Rusty here, and I've been staring at the charts for our little patch of ocean. Gotta be straight with you – the next week and a half is a bit of a write-off, but the end of the run is looking like something special. Let's get into it.
The only real break on the radar for this whole outlook is Whale Rock. It's a reef setup, so it needs a specific swell direction to really fire, and unfortunately, for the first week and a half, the wind is the main problem. We’re looking at a massive gap in quality surf from now until the middle of next week. The first few days are a total no-go. Tuesday the 8th is a mess – cross-on winds from the NE at 16 mph, smashing up a small 3 ft to 3 ft SSE swell. The energy is weak to moderate, and it's just choppy, lumpy garbage. That pretty much sums up the next several days: small waves, onshore or cross-shore winds, and poor conditions. We get a sniff of something on Sunday the 13th with a 3 ft SSW groundswell (17-second period) and a light onshore breeze, but the energy is still moderate and the forecast says it's marginal. It's just not enough to get excited about.
Then we hit the doldrums again. Monday the 14th is a write-off with 25 mph winds, and Tuesday the 15th starts with a tiny bit of hope – glassy conditions and a 2 ft SSE swell – but the energy is weak and it's just ordinary. Honestly, the first 10 days of this forecast are a total blank. For a spot like Whale Rock, which is already inconsistent, this kind of run isn't a huge surprise. The forecasts can change, but right now, it’s a waiting game.
Now, hold on to your board, because the second week is where it gets interesting. The real standout is shaping up for Thursday, the 17th of September. The swell is going to jump up, but it's a tricky one. We're looking at a 8 ft to 10 ft SSE swell, but with a short, weak period (7 to 8 seconds). The energy is strong, but that short period means it's going to be fat and messy, especially with a moderate cross-shore wind. This is pure expert territory – over 8 ft and short period is a handful. It's a marginal call, but it’s the first real sign of life.
The true standout, and I mean the one you circle on the calendar, is Saturday, the 19th of September. This is the one. We’ve got a solid 10 ft easterly swell, with a 10-second period, producing very strong wave energy. The wind is a cross-offshore from the SW, and the forecast says it's *clean*. For a reef break like Whale Rock, a clean 10 ft E swell with an offshore wind is about as good as it gets. The direction is a little off from the optimum S direction, but the size and the clean conditions will iron that out. It’s big, it’s powerful, and it’s for experts only. The crowd could be a problem here – it's a known spot and on a swell like this, it'll be busy.
Sunday, the 20th is also a solid option, with a 10 ft E swell and a moderate cross-shore wind, but it's not as clean as Saturday. The energy is still massive, but that cross-shore wind will make it a bit bumpier. The following Monday and Tuesday (21st and 22nd) still have size, but the onshore winds return, making it less appealing.
So, to wrap it up: forget the first week and a half. The best bet by a long shot is Saturday, 19th September at Whale Rock. Big, clean, and powerful. It's a long-range call, so it's promising but not a sure thing, but if it comes together, it's going to be a day to remember. For the rest of us, the 17th offers a lumpy, expert-only option.
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.
