The Lowdown
Alright folks, Rusty here. Let's have a yarn about what's comin' our way at The Core. It's a bit of a slow burner, this one, so don't go paddlin' out just yet.
We're lookin' at a real dry spell for the better part of the first week. The start of the forecast period is pretty much a write-off for any decent surf. For Wednesday the 19th of August, we've got a tiny 3-foot east-northeast swell with a short, weak period of 7 seconds, and on top of that, there's a risk of thunderstorms and onshore wind. It's not lookin' good, mate. The wave energy is next to nothing (100), and the conditions are just poor. Thursday the 20th afternoon shows a glimmer with glassy conditions, but it’s still only a 4-foot, 8-second swell from the east-northeast, and it's described as very ordinary. You'd be hard-pressed to get a good one.
Honestly, you can pretty much write off the first week. There's a long gap of very ordinary to poor surf with tiny, weak swells. The best you'll get is some glassy windows on the 20th and 23rd of August, but the swell is just too small and gutless to get excited about.
Now, the real story starts to build late in the second week. Keep your eyes on the 26th of August. Wednesday morning, we see a solid 5-foot swell from the east with a proper long period of 14 seconds, and the wave energy jumps right up (866). That's a groundswell signal. The wind is onshore, which is a pain, but it’s only a light breeze. The real standout, the one you wait for, is the afternoon of Thursday, the 27th of August. The Core is gonna fire with a solid 8-foot groundswell from the east, a very long period of 16 seconds, and then the wind goes glassy. The energy is massive (3030), and the report says it’s excellent for experienced surfers. For a beginner spot like The Core, that size (over 8 feet) is strictly for the experts. The crowd factor is something to consider too—it says crowds are "sometimes", so you might have a few out, but on a setup like that with glassy conditions, it’ll be worth the company.
Friday the 28th keeps the size up around 8 feet from the east (14-second period), but the wind swings cross-onshore, so it won't be as clean. By Saturday the 29th and Sunday the 30th of August, the swell jumps to 10 to 12 feet from the east-northeast, but the model flags it as "too big for this break." At that size, it’s a washing machine, even for the skilled lads. It's not for paddlin', might be more of a kite session.
So, for the one standout: Thursday, 27th of August, afternoon. Glassy conditions, a clean 8-foot east swell with a long 16-second period at The Core. It’s a groundswell, so expect sets with lots of push. That’s the one day in the whole 16-day window that's truly worth circling on the calendar. All other days are either too small, too onshore, or too big for what The Core can handle.
Stay frothy.
Rusty.

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.
