The Lowdown
Alright folks, Rusty here. Let’s get into it.
Well, I’ll be honest with you, the outlook for The Core over the next 16 days is a bit of a mixed bag, and it’s going to take a little patience. The swell is coming in, but it’s going to be a fight with the wind for most of the period. The Core is an exposed spot, but it’s a beginner-friendly wave that’s inconsistent, so it needs perfect conditions to really shine. The water temp is sitting at 83°, which is about average for this time of year, so no worries on that front.
The forecast kicks off on Sunday, September 6th, with a real beast of a swell. We’re looking at a solid 12 ft NNE swell with a 10-second period. The combined energy here is a massive 4252 (strong to very strong energy). But here’s the catch – that’s way too big for a beginner spot like The Core, even with the wind and tide being favorable. It’s a Sunday morning, so it’s a spectacle, but not a paddle. That afternoon sees the swell drop a touch to 10 ft, but it’s still over the top for the crew on shortboards.
Monday the 7th through Wednesday the 9th is a bit of a write-off, sorry. The swell drops to around 6 ft to 7 ft, but the wind is cross-onshore and choppy from the N and NNW. The energy is moderate (between 447 and 666). The wave comment is “poor surf conditions,” and I’m not going to argue with that. The Core just isn’t handling that wind direction well.
Thursday the 10th and Friday the 11th are marginal. The swell is still around 5 ft to 7 ft, and the wind is cross-onshore or onshore. The energy is moderate (511 to 626). The rain and storms don’t help the vibe. It’s a bit of a wait-and-see, but the tide and wind are questionable.
Then we get a bit of a spike on Saturday, September 12th. The swell jumps to 8 ft from the E with a 10-second period, and the energy is strong at 1477. But the wind is cross-onshore from the E at 12 mph, so it’s going to be choppy and messy. That size is still too big for beginners, and the wind is a killer. The afternoon is a little better with a 7 ft E swell, but the wind is still onshore.
The period from Sunday the 13th to Tuesday the 15th is a slow decline. The swell drops to 4 ft to 6 ft, and the wind is mostly cross-shore or cross-onshore. The energy drops to between 197 and 478. The waves are small and weak.
Now, here’s the one true standout. Tuesday, September 15th in the afternoon. The swell is a clean 5 ft from the E with an 8-second period, giving a moderate energy of 502. But the real story is the wind: glassy. Totally calm. The forecast says “expect very good surf conditions.” This is your window. The Core is inconsistent, so this is a rare, perfect moment. The waves will be clean and fun, even if the period is a bit short. It’s the only day I’d be circling on the calendar.
After that, from Wednesday the 16th onwards, it all goes a bit flat. The swell drops to under 4 ft, and the wind is light but not ideal. The energy is weak (152 to 388). The last week of the forecast is a lot of “poor surf conditions” and “marginal” calls. Nothing to get excited about.
So, the bottom line: The Core is a spot that needs a perfect storm of conditions, and we only get one brief window. The first week is too big or too windy, and the second week is too small. If you’re after a surf, hold out for Tuesday afternoon, September 15th. That’s your best bet. Given the inconsistency of the break, a blank run like this is just part of the deal here.
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.
