The Lowdown
Alright, folks, let's talk about The Core. It's gonna be a long haul this time. The next week is a total dead loss – flat, weak, and wrong-direction swell. You'd be wasting your time staring at it.
The first few days are just hopeless. The 15th has a 5ft NE swell, but with a 7-second period, it's just wind chop. The wind is onshore, blowing 15 km/h from the NNE. You'd be out there fighting it for nothing. It drops to 4ft and then lower, and it's just not breaking with any sort of shape. We don't see anything worth mentioning until the 20th.
That's when we get a bit of a pulse. Swell period jumps to 13 seconds, and the energy starts building. The afternoon of the 20th has 4ft of ENE swell with that longer period, and the energy is moderate at 605. But the wind is cross-onshore from the north, so it's lumpy. The 21st sees a bit more size, 5ft, but still cross-onshore. It's not good.
The one session that stands out above the rest is Monday the 28th. We get a 5-6ft ESE swell with a 13-second period. The energy is strong, 882, so there's real power in the water. The direction is still not perfect, but it's the most surfable we're going to see. The wind is still cross-onshore from the NNE at 15 km/h, so it'll be a bit bumpy, but if you're keen, that's your window. After that, it fades out again.
So, there you have it. A lot of nothing, with one glimmer of hope around the 28th. The Core is a beginner spot, and with these winds, it's going to be a mess. Maybe more of a novelty for the experienced crew on that Monday. The water is warm, about 81°, so that's a plus, at least.
I'd say stay home this week. Keep an eye on that 28th, but don't get your hopes up too high. These long-range forecasts are never set in stone.

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.
