The Lowdown
Howdy, Rusty here. Let’s break down what’s cooking at The Core for the next couple of weeks.
Right off the bat, it’s a long, slow grind. There’s no real surf to get excited about for over a week. A good seven or eight days of pretty flat and poor conditions, so save your energy. The first sign of life doesn’t show up until Sunday the 20th of September.
On that Sunday, we get a bump in size to about 6 to 6 ft from the ENE, with a super long period of 15 to 16 seconds. That’s proper groundswell energy, and the combined energy is up there at 1626 (moderate wave energy). The catch is a moderate cross-onshore breeze from the NNW at 12 mph, so it’ll have some chop on it. The swell direction isn’t perfect for The Core, which likes it from the NE, but it’s the most wave we’ve seen in a while. It’s a bit much for a total beginner, but fine for anyone with a few sessions under their belt.
The standout is Tuesday the 22nd of September. By the afternoon, the wind goes totally glassy, calm as a lake. The swell is a clean 5 ft from the NNE with a solid 10-second period. The combined energy is 533 (moderate wave energy). The direction is spot on for The Core, and the wind is perfect. This is the call of the period. The waves will be clean, smooth, and offer up some real quality rides. It’s not a giant swell, but it’s the best combination of size and wind you’ll see. Just keep in mind the break can be inconsistent, and there’s a chance for some company in the water.
After that, it fades back to smaller, weaker surf with those light cross-onshore breezes coming back. Nothing else worth rushing for.
Water temp is 81°F, which is right where it should be for this time of year.
So, if you’ve got one day to paddle out, make it the afternoon of Tuesday the 22nd of September at The Core. That’s your cleanest, glassiest window.
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.
