The Lowdown

G’day, I’m Rusty. Let’s have a look at what’s on the cards for The Groyne over the next couple of weeks. Straight up, I gotta be honest with you—it’s a lean run. This reef break is fairly consistent, but the next 16 days are mostly a write-off for proper waves. There’s a gap right from the start with nothing worth paddling out for until the morning of Thursday the 3rd of September, and even then it’s only scraping a 1 out of 10. The whole stretch is peppered with poor surf conditions and messy winds, so you’ll be waiting a while for anything decent.

The best of a bad lot pops up on Monday afternoon, the 14th of September. We’ve got a clean offshore breeze from the WNW at 10 km/h, which is a beauty for a reef break like this—it’ll keep the face smooth. Swell is tiny though, only 2ft from the ENE, with a period of 6 seconds, so it’s weak energy (51). It’s surfable but very ordinary—think small, crumbly waves for a longboard or a mid-length. The water temperature is about average for the time of year, so nothing wild there. Crowds are sometimes an issue here, with the optimum swell direction from the SE, and we’re getting ENE, so it’s not lining up perfectly. Still, for the window we’ve got, this is the standout—just don’t expect much.

The afternoon of Tuesday the 15th of September offers similar tiny 3ft ENE swell (80 energy) but with a cross-onshore breeze from the NE at 15 km/h, chopping it up. Not worth the drive. The rest of the period is mostly small, short-period slop with cross or onshore winds, or clean but flat mornings like Saturday the 12th of September—glassy conditions but only 2ft of swell (76 energy), and very ordinary. There’s a bump in energy on Thursday the 10th of September (4ft SE swell, 163 energy), but cross-onshore winds at 25 km/h ruin it for surfing. That setup looks more interesting for kite surfing than paddle surfing.

Overall, if you’re desperate, the 14th is your shot. Otherwise, it’s a long wait.

Rusty.

Information about the The groyne Surf forecast

The above surf forecast table for The groyne provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The groyne can be found by selecting the local surf guide option on the grey menu. Our The groyne 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 groyne) 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 groyne 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.
