The Lowdown
Alright, this is Rusty here, checkin’ in from The Groyne. We’re looking at a pretty flat and frustrating 16-day window, so let’s get real about it.
Right off the bat, from now (August 28th) all the way through to the morning of September 7th, it’s a long, grim stretch. That’s over a week of barely a ripple worth paddling for. The swell is tiny or too short-period, the wind is constantly messing it up – mostly onshore or cross-shore crap. Kites might dig the breeze, but for us surfers? Forget it.
Mornings around September 2nd and 3rd have a tiny pulse (2ft to 2ft from the E and ENE) with clean conditions – Wednesday the 2nd is glassy, Thursday the 3rd has a clean cross-offshore breeze from the NNW. But at 2ft and 7-10 second periods, we’re talkin’ barely surfable waves. The energy is weak – between 75 and 80 (two-digit values). It’s a tease, not a session.
The one true standout is the morning of Monday, September 7th. Finally, a change. We’ve got 5ft of SE swell, and a light cross-offshore breeze from the SW. That wind is gonna clean it right up. The combined energy is moderate at 216 (three-digit value). The break is a reef setup and exposed to the swell. The period is short though, only 6 seconds, so the waves will be a bit crumbly and close together, not the kind of long wall you’d dream of, but it’ll be the best we’ve seen in ages. The water temperature is about average for this time of year. Crowds are sometimes a thing here, so get there early.
After that, it drops again quick. Tuesday and Wednesday, September 8th and 9th, see some waist-high swell (4ft to 3ft) but the wind goes onshore from the SE, so it’s back to choppy junk.
Rusty, out.

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.
