The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s cookin’ for The Core over the next couple of weeks.
Right off the bat, we’re in for a bit of a slow start. Monday the 31st of August is a write-off with risk of thunderstorms, a cross-shore wind, and weak energy in the water (58). The swell is a messy 2 ft from the east, and at 8 seconds it’s not doing much. By the afternoon, the swell jumps to 7 ft, but it’s short-period junk from the ESE, and the energy is still only moderate (325). Not worth paddling out.
Tuesday the 1st of September is where we start to see a glimmer. The morning is glassy with a light swell from the east at 3 ft and 9 seconds, and energy ticks up to 219. The afternoon gets even better – glassy conditions, 5 ft of east-northeast swell at 9 seconds, and energy climbs to 300. It’s not big, but it’s clean, and the break is exposed to the east-northeast, which lines up nicely. For a beginner spot that’s inconsistent, this is a good window to get a few foamy ones.
Wednesday the 2nd sees a mix. The morning has a light cross-shore and 4 ft from the northeast at 9 seconds (269 energy) – it’s marginal. But the afternoon glass-off returns with 4 ft from the northeast at 10 seconds (226 energy). It’s clean, but the consistency is still wonky.
Thursday the 3rd is a write-off in the morning with a cross-shore and weak energy (164). The afternoon improves with a clean cross-offshore wind and 4 ft from the north-northwest (200 energy), but the period is short at 7 seconds.
Now, here’s the standout: Friday the 4th of September. The morning is glassy with 6 ft of north swell at 9 seconds, and the energy jumps to 980 – that’s strong. The afternoon is also glassy with 6 ft from the north (780 energy). The wind is light and clean, the swell direction is near the optimum northeast, and the energy is pumping. This is the best session of the whole forecast. The Core is a bit inconsistent, but when it fires like this, it’s worth the wait.
Saturday the 5th has a light cross-shore in the morning with 5 ft from the north-northeast (336 energy) – marginal. The afternoon sees 7 ft from the north (1237 energy) but with a cross-onshore wind, so it’s bumpy.
Sunday the 6th and Monday the 7th are messy with onshore and cross-onshore winds, and the swell is 6 ft to 7 ft but with a short period and poor energy (352 to 494). Not great.
From Tuesday the 8th, the swell starts to get longer period but the wind is still cross-onshore. The 8th morning has 4 ft from the east at 14 seconds (786 energy), and the afternoon has 4 ft from the east at 13 seconds (1064 energy). The energy is moderate to strong, but the wind is a problem.
Wednesday the 9th is a big one – 8 ft to 8 ft from the east at 12 to 13 seconds, with energy soaring to 1844 and 2535. The wind is onshore to cross-onshore, so it’s bumpy, but the swell is serious. For a beginner break, this is getting too big for most.
From Thursday the 10th onward, the swell goes ballistic. 10 ft to 15 ft from the east-northeast and north-northeast, with periods of 10 to 13 seconds, and energy values from 2830 to 9402. The wind is cross-onshore or onshore, and the guidance says the swell is too big for this break. This is expert-only territory, and even then, it’s going to be a washing machine. This run of big, powerful swell continues through to Tuesday the 15th of September. The Core is a beach-and-reef setup, and with this much energy and swell, it’s looking more interesting for kite surfing than paddle surfing.
So, if you’re after a wave, your best bet is Friday the 4th of September. Clean, glassy, strong energy, and the swell is just right. After that, it’s either too small and clean, or too big and messy. The Core is inconsistent, so when it lines up, you’ve got to be on it.
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.
