The Lowdown
Alright, mates, Rusty here again. Let’s break down the same outlook but in feet and miles per hour, because that’s how we feel it.
The first few days are a bit of a dud, with tiny, weak waves and poor conditions. But hang tight, because there’s a serious pulse of energy coming, and a couple of windows where it’ll all come together.
The real standout is on Monday, August 3rd. We’ve got a clean little groundswell rolling in from the east at 2ft, with a long 15-second period. The magic touch is that glassy afternoon wind, which will have the surface looking like a mirror. The water temperature is sitting at 84°, which is about average for this time of year. The combined energy is moderate at 234, and while it’s not huge, that long period means the waves will have some shape and punch. This is the best small-wave session on offer.
Then, things get… well, they get a bit heavy. From Tuesday, August 4th through to Saturday, August 8th, the swell just keeps building, with the east swell topping out over 10ft and periods hitting 19 seconds. The combined energy spikes into the thousands (6,416 on the 6th), which is serious power. But for a beginner-friendly spot like The Core, anything over 8ft is expert territory. In fact, by the 6th and 7th, the swell is predicted to be too big for this break. The winds are mostly offshore on those big days, but the size and power will make it a gnarled, challenging beast. If you’re an expert, you might get a thrill, but for everyone else, it’s a look-don’t-surf situation.
After that big swell, the wave heights drop back down fast. The 9th and 10th of August see a return to small, weak surf (1ft to 1ft) with very little energy.
We get a second, smaller pulse on Tuesday, August 11th, with a chest-high east swell at 3ft and a 13-second period. The wind turns cross-off in the afternoon, cleaning it up nicely. The combined energy is moderate at 277. Then on Wednesday, August 12th, we get another glassy afternoon with the same 3ft swell from the east-northeast. Both of these afternoons offer clean, fun waves for a longboard or a fish, but they’re not as solid as the 3rd.
After that, it fades back into small, choppy, and onshore junk for the rest of the window. The best bet is to pencil in August 3rd for a glassy, user-friendly session, and if you’re a strong paddler, the big days from the 4th to the 8th might be a wild ride.
Rusty out.

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