The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
Truth be told, the next week or so is a bit of a write-off. There’s no surf worth paddling out for until we get deep into the second week. For a solid stretch there’s just nothing doing – a long gap with no real recommendations. The few tiny, weak pulses we see are ruined by poor conditions or just not enough to get excited about. It’s one of those quiet runs for the area.
Now, if we can be patient, things change around Sunday, August 23rd. The Groyne has a bit of a window. That Sunday morning is looking glassy with an offshore breeze, and we’ve got 6ft of east swell rolling in at 11 seconds. That’s a proper groundswell period, so those waves will have some shape and energy. The combined energy is solid at 639 – moderate wave energy, but it’s got some grunt. The swell direction (E) is a good match for this reef break that likes it from the southeast. Water temps are sitting around average for this time of year, so nothing wild there. This is the standout of the whole run.
Then Monday, August 24th morning keeps the good vibes going: 6ft from the east, still a long 11-second period, and clean with a cross-off breeze. Combined energy is 771. That’s a strong session in the making. The Groyne can get crowded sometimes, so keep that in mind, but with conditions this clean, it’ll be worth jostling for a few.
Tuesday, August 25th morning is the last real highlight – 8ft of east swell, 8-second period, clean with a cross-off wind. Combined energy jumps to 676. That’s getting solid, but for the more experienced crew; 8ft with a bit of power will be a handful for beginners. The afternoon goes onshore and messy.
So, bottom line: hang tight through the dry spell. Sunday the 23rd and Monday the 24th of August mornings are your best bets – glassy, clean, and with some proper east swell energy. Tuesday morning is also good for the advanced surfers. After that, the window starts to close again.
Stay patient, and I’ll see you out there.
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.
