The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up at The Groyne.

We’ve got a bit of a slow start, but things get interesting if you’re willing to wait. The first few days are a bit of a write-off with messy, choppy conditions, but there’s a real gem hiding out towards the end of the forecast.

The best window shapes up for the morning of Thursday, 6 August. That’s the standout. The Groyne is a reef break, and it’s exposed to the swell. On that morning, we’re looking at a solid 6 ft swell from the SE with a clean, offshore wind from the W at just 3 mph. That’s near-perfect wind for this spot, and the water will be glassy and clean. The combined energy is pumping in at 682 (moderate-to-strong wave energy), and the period is a workable 8 seconds. This is the one to circle on the calendar. It’s a morning for the intermediate crew, as that size is a bit too much for beginners.

Leading up to that, we have a few smaller, cleaner windows. The morning of Thursday, 23 July offers a clean 4 ft swell from the E with a light SW cross-offshore breeze at 3 mph. The energy is moderate at 210, and the period is a short 8 seconds. It’s a small, clean session.

Saturday, 25 July morning has a 5 ft swell from the SSE with a clean SSW cross-offshore breeze at 9 mph, giving moderate energy of 497. It’s surfable and clean, but the wind is a bit stronger.

Then there’s a big gap of almost no surfable waves from the afternoon of 25 July all the way through to the end of July and into early August. It’s a long, flat, or poor run. A few tiny bumps show up, like the morning of 1 August with a 1 ft ESE groundswell (period 15 seconds) and glassy conditions, but the energy is weak at 138. It’s only for the longboard or a very patient surfer.

The next decent option after the long dry spell is the morning of Tuesday, 4 August. We get a 3 ft swell from the ESE with a clean NNW cross-offshore breeze at 3 mph, giving moderate energy of 207. It’s small but clean.

But for the real power, it’s all about that Thursday, 6 August morning. For the rest of the afternoons, the wind tends to turn onshore and mess things up. Keep an eye on that morning session.

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.
