The Lowdown
G’day, it’s Rusty here. Let’s be straight with you: the next couple of weeks are going to test your patience if you’re chasing proper waves. There’s plenty of swell on the way, but the wind and the conditions are going to be fighting us for most of it. We’ve got a long stretch of poor surf to get through before we finally see something worth paddling out for.
Looking at the big picture, we start with a bit of lumpy, cross-shore chop that just isn’t going to do the job. The energy in the water is there – with moderate wave energy (481 to 564) – but the southwest swell is being chopped up by a fresh northwesterly breeze. This is a beach and reef setup, and with conditions like that, it’s more about survival than style. You’re better off staying on the sand for the first few days.
Friday and Saturday see the swell build solidly – we’re talking 4ft on Friday morning, ramping up to a powerful 10ft by Saturday afternoon. The energy numbers are telling the story too, climbing through strong (1316 to 1882) and into very strong territory (3874 to 5118). But honestly, with fresh cross-onshore winds and a lumpy, choppy mess, this is going to be a washing machine. That kind of size and wind on a beach and reef setup is a recipe for a beating. It’s not a surfer’s wave at that point; it’s more interesting for the kite crew. Best to sit this one out.
Sunday offers a little let-up with the swell easing, but it’s still marginal. The wind lightens up, but it’s still onshore, so you’re looking at small, bumpy waves. Monday brings a fresh cross-offshore breeze, which will clean the surface up nicely, but the swell has dropped back to a modest 5ft and the energy has faded back to moderate (843). It’s a tease – clean but not really pushing.
Tuesday and Wednesday look pretty forgettable. Small, inconsistent swell with a mixed bag of winds. We need to wait for the real window.
Now, here’s your standout. Mark Friday, August 28th on your calendar. The forecast is for a light offshore breeze from the northeast – that’s glassy, clean conditions – and the swell is up to 8ft from the southwest with a very long period of 17 seconds. That’s a proper groundswell, folks. The wave energy is pumping at 3057. Yes, the size is getting up there, but it’s still fit for experienced surfers who know their way around. That kind of period and direction is going to set up beautiful lines at Cape Paterson. This is the day we’ve been waiting for. The morning window looks like the pick, as the wind shifts onshore later.
The rest of that weekend and into the following week drops back down. Saturday (Aug 29) has some clean cross-offshore conditions with smaller swell, which is fine for a cruise, but the magic is gone. The following week’s forecast gets smaller and more inconsistent, with the wind swinging around a lot. There are brief clean windows here and there, but nothing that’ll get your heart racing. The swell energy is weak (274 to 441) and the waves are pretty ordinary.
So, to sum it up: the first week is a loss for the most part. Don’t get tempted by the big numbers – they’re not your friend with that wind. Your best bet is the morning of the 28th. That’s your window for something special. After that, it’s a waiting game again.
Stay patient, and stay stoked.

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