The Lowdown
Alright, this is Rusty, and I’ve been staring at the charts for The Groyne. Let’s be straight with you, mate – the next 16 days are a bit of a tough watch for this spot.
We kick off Friday the 28th with a tiny 3 ft swell pushing in from the east-northeast. It’s combined energy is only moderate (137) and the wind is a light cross breeze, but the call is already poor surf conditions – just not enough push or shape. That theme sticks all weekend. Saturday sees a bit more energy on the Sunday morning with a 6 ft SE swell (moderate-strong energy at 330), but the wind whips up to 19 mph from the SSE creating a lumpy cross-chop. It looks more like a kite surfer’s day than a paddle surfer’s.
Most of the first week is a write-off. Monday is messy with rain showers and onshore wind. The water temp was noted at 69°F on Friday, which is just about average for this time of year with a slight anomaly of -0.9°F – nothing unusual.
Then, a glimmer. On Wednesday morning, September 2nd, we get a tiny 2 ft easterly swell (10-second period, moderate energy at 63) with glassy conditions. The wind is from the north at just 3 mph. The surf is small and ordinary, but the clean conditions make it ridable. A morning session for the longboard or a foamie might just be the go if you’re desperate.
Thursday the 3rd has a similar story in the morning – glassy, with a 1 ft east swell (52 energy). But again, it’s small and the quality is only “surfable but very ordinary”. There’s no standout surf at all here.
The second week is flat and almost lifeless. From the 4th through to the 12th, we are looking at swell heights stuck between 1.0 ft and a brief bump to 3 ft on the 6th, but that bump comes with a horrid 5-second period and a 19 mph crosswind. There is one interesting note: the morning of the 9th shows a 1 ft swell from the southeast with a very long 19-second period (low energy at 119). That’s a groundswell, but at this size it’s just a clean ripple on the reef – not enough to surf.
There are no standout days. The only thing even worth mentioning is that glassy small window on the morning of the 2nd and 3rd of September. But a true highlight? Sorry, there isn’t one in this 16-day run. For The Groyne, it looks like we wait.
Stay patient.

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.
