The Lowdown

Alright folks, Rusty here. Let’s get straight into it. The next 16 days are a real mixed bag for The Core. We’re starting with a big flat spell, so don’t bother paddling out for the first few days – it’s basically a lake.

From Wednesday the 30th of July right through to Sunday the 2nd of August, we’re looking at tiny, weak waves. The swell is a pathetic 0.7ft to 1ft from the ESE, with a short period of 9-10 seconds. The combined energy is just a dribble – between 9 and 27 – so it’s all poor surf conditions. The wind does go glassy a few times, which is a tease, but there’s just no push. Save your wax.

Now, things start to get a bit more interesting from Monday the 3rd of August. The swell picks up slowly, but it’s still messy. On Monday morning we’ve got 2ft from the east at 16 seconds, energy is 128 (weak), and it’s cross-onshore. Not good. The Core needs that NE optimum swell direction, and we’re not getting it.

The real standout window is Wednesday the 5th of August into Thursday the 6th. This is the best on offer. Wednesday afternoon sees a clean 5ft swell from the east, with a long period of 18 seconds. The wind goes glassy, and the combined energy jumps to 1619 (strong). That’s proper groundswell. The Core is an exposed beach setup, so that long period stuff (18 seconds) can make it a bit straight and tricky, but for experienced surfers, this is excellent.

Thursday the 6th is even bigger. Thursday morning is 6ft, still from the east, period 18 seconds, energy hits 2192 (very strong). The wind is light cross-onshore, so it’s a little lumpy. But Thursday afternoon? That’s the pick. 6ft, east swell, 18 seconds, glassy wind, and the energy is 2222 (very strong). That’s a solid, powerful groundswell with clean conditions. However, at 6ft, this is pushing into expert territory for a beach break like The Core. It’s going to be powerful and lined up, but the crowds are likely to show up.

After that, it fades. Friday the 7th still has some size (5-6ft) but the wind swings cross-shore, knocking the shape. By Saturday the 8th, the swell drops to 4-4ft, and the period shortens. The second week from the 9th of August onward is poor again – small, onshore, and short-period slop, with energy mostly under 300. A few days see wind swell with a 6-second period, which is just bumpy junk.

To sum it up: the first week is a total write-off until the 5th. The best waves you’ll see are Wednesday afternoon the 5th and Thursday afternoon the 6th. That’s your window. Big, clean, powerful groundswell, but make sure you’ve got the skills for a 6ft east swell at a beach break. It’s a long-range call, so keep an eye on it, but it’s got promise.

Stay stoked,
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.
