The Lowdown
Alright folks, let’s be honest with ourselves. The start of this forecast period is pretty lean. The Groyne is doing its usual thing – not much swell, and the wind’s just messing it up. Saturday the 8th is a total washout, just some small, choppy leftovers.
But then we get a glimmer. Sunday the 9th, the swell bumps up to about chest-high, pushing 3 feet, with a nice pulse of east energy. The morning is looking glassy with that light southerly breeze, and it’ll be one of those rare clean windows. It’s not going to be a classic, but it’s a proper surf. Get out early before the onshore kicks in later.
After that, it’s a bit of a snooze-fest for the next week. The swell drops off to knee-high at best, the energy is weak, and the winds are all over the place. We hit a proper flat spell from the 13th to the 15th. Honestly, you’d get more exercise walking the dog.
Then things start kicking up again around the 16th and 17th, but it’s a messy, short-period SE windswell. The energy numbers start climbing, but it’s stormy, rainy, and blown-out. This is not a paddle-surfing setup – it’s more like a kitesurfing day. The waves will be there, but they’ll be lumpy and chaotic.
But wait, the good stuff is coming. The real deal arrives on Friday the 21st. We’ve got a clean 2.1m (about 7 feet) of ESE groundswell pumping in with 608 units of energy. The winds are light offshore, so the faces will be smooth and lined-up. That’s a proper day for the intermediates.
And then Saturday the 22nd... hold on. This is the one. The swell jumps to a solid 2.5m (over 8 feet) with a massive 1209 units of energy. That’s serious, powerful surf. The morning looks clean with light offshore winds, so if you’ve got the skills, this is your time. The afternoon gets a bit sideways with a moderate cross-shore, so make the most of the morning session.
Sunday the 23rd backs down a touch to a still-solid 1.7m (about 5-6 feet), but it stays clean with that offshore breeze again. A great finish.
So, the story is: this week is slow, and the middle of the month is essentially flat. But the final three days, from Friday the 21st through Sunday the 23rd, are the standout of the entire run. It’s a long-range call, so don’t book your flights just yet, but it’s looking very, very promising.
This is Rusty, keeping it real. See you in the water.

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.
