The Lowdown
Alright folks, Rusty here with the long-range outlook for Cape Schanck. This is a solid reef set-up that demands respect, and the coming days are a real mixed bag.
Right now, the water temp is sitting at 57°F, which is about average for this time of year, so no surprises there.
The first week is pretty grim, to be honest. We’ve got a lot of lumpy, onshore wind and blown-out conditions. There’s a bit of swell on Thursday the 20th, but it’s tiny at 2ft and the 30 km/h north-westerly has it all chopped up. The energy is weak (313), so it’s a hard pass. Friday and Saturday are no better; Saturday the 22nd sees a jump in size to 8ft from the SW, but it’s a straight onshore gale, making it a mess. That’s expert-only territory for the size, but the wind ruins it.
We finally get a window on Sunday the 23rd afternoon. The swell drops to a clean 6ft from the SW, but the real story is the wind swinging light northerly at 10 km/h, giving us a nice cross-off clean-up. The energy is still strong (1753), and the period is a solid 13 seconds. This is the standout for the first week. It’s a quality, clean wave for experienced surfers.
Monday the 24th is a letdown with another fresh breeze ruining the shape. Tuesday through Thursday are all marginal with onshore winds and messy conditions. The period on Wednesday the 26th drops to 13 seconds, so the energy is fading.
The real hope comes later. On Thursday the 27th afternoon, we get a small but clean 4ft swell from the SW with a light north wind. The energy is moderate (930), but the conditions are clean. Then, Friday the 28th looks proper. The morning has a 7ft SW swell with a long 17-second period, and a light NNE cross-off. The energy is very strong (2953). That’s a big, powerful groundswell with clean conditions. Expect long waits between sets, but the shape will be solid on a reef. It’s one for the experts.
Saturday the 29th offers a nice morning session with a 5ft SW swell and a gentle offshore breeze from the NE. The energy is moderate (839) but the conditions are clean. Good for a relaxed session.
The second week starts to fade. Sunday the 30th is a write-off with 50 km/h winds, even if it’s cross-off. The swell is too small and the wind is a gale. Monday the 31st afternoon shows a bit of promise with a 4ft SW swell and a light NNE breeze, clean conditions, and moderate energy (1040). That’s the best of the later part. The rest of the week into early September is mostly small, weak, and onshore, with nothing to get excited about.
So, the pick of the entire window is Sunday 23rd afternoon for the clean, quality waves, and Friday 28th for the big, powerful groundswell if you’re an expert. Get on it while you can.
Rusty.

Information about the Cape Schanck Surf forecast
The above surf forecast table for Cape Schanck provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cape Schanck can be found by selecting the local surf guide option on the grey menu. Our Cape Schanck 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 (Cape Schanck) 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 Cape Schanck 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.
