The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way.
The long-range picture is a bit of a mixed bag. We’ve got a decent swell window opening up, but the wind is going to be the main character for most of the run. The first few days are a write-off, but there’s a small window that looks like the real deal if you’re patient.
The Groyne is a reef setup, and it's fairly consistent when conditions line up. The water temp is sitting at 68°, which is a bit colder than normal for this time of year, so you might want a slightly thicker spring suit.
We’ve got a total blank to start. Thursday the 6th and Friday the 7th are a no-go with poor surf and cross-onshore or cross-shore breezes. The swell is tiny and weak. Saturday the 8th is much the same story – light winds but the swell is too small and messy to bother with.
Okay, Sunday the 9th. This is the one. Early morning, we’ve got glassy conditions, 3ft of east swell with a 9-second period. The energy is moderate (211), and the wind is dead glass. This is the standout of the whole forecast. The swell is a bit small for a big day, but it’ll be clean and lined up. Light crowds are possible, so get in early. The swell direction is a touch east of the optimum south-east, but it’s a solid, fun wave.
After Sunday morning, the wind swings around and the surf quality drops off a cliff. Sunday afternoon gets choppy, and Monday the 10th turns offshore with a fresh breeze from the WSW, but the swell drops to 3ft and the energy is weak. It’s clean, but barely surfable. Tuesday the 11th is similar – small, clean, but very ordinary. Wednesday the 12th sees a jump in size to 5ft, but it’s a short-period, wind-affected mess from the north-northeast. Then it’s a long, slow decline into tiny, weak surf for the rest of the week.
The second week gets a bit ugly. From the 15th onward, the swell starts to build again, but the wind is all wrong. Saturday the 15th has a 5ft swell but it’s cross-onshore and short period. The real trouble starts Sunday the 16th with a 8ft south-east swell packing heavy energy (524), but it’s accompanied by a fresh cross-shore wind that’s going to make it lumpy and difficult. This is expert-only territory, and even then, it’s going to be a battle. The wind stays strong and cross-shore right through to the 20th, with the swell hovering between 6ft and 7ft. The whole setup is messy, cross-onshore, and with rain showers. Honestly, for a beach-and-reef setup like this, it looks more interesting for kite surfing than paddle surfing during that stretch.
So, to sum it up: your one and only true standout is Sunday morning, the 9th of August. Get it while it’s good. The rest is a long wait for more wind and swell that won’t cooperate.
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.
