The Lowdown

Alright, Rusty here, breaking down the surf for The Groyne. The water’s running at 68°, which is a touch colder than usual for this time of year, so keep that in mind.

To be straight with you, the next 16 days are a bit of a slog. The Groyne is a reef break that’s fairly consistent and likes a SE swell, but the wind and conditions are just not cooperating for most of it. We’re looking at a lot of poor conditions, so you’ve got to pick your moments.

The real highlight is Sunday morning, August 9th. That’s your best bet. You’ve got a 4ft easterly swell with a 9-second period, and the wind is glassy – dead flat. That’s going to be clean. The combined wave energy is moderate at 253. It’s not a big swell, but with the wind off, it’ll be the best quality you’ll see. Just know it can get a little busy sometimes.

After that, it’s a long stretch of mediocrity. From the 10th through the 19th, the wind is mostly onshore or cross-shore, making things choppy. The swell stays small, mostly 2ft to 3ft, with a lot of short-period slop. There’s a tiny window on Wednesday afternoon, the 12th, with a clean offshore wind but only a 2ft swell – it’s surfable but nothing to write home about.

Towards the end, on the 20th, we see some longer-period groundswell from the SE at 12 seconds and 2ft, but the wind is straight onshore again, ruining it.

So, bottom line: Sunday the 9th is the day to circle. Everything else is a grind. It’s a tough run, but it won’t stay this way forever.

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.
