The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for The Groyne over the next couple of weeks. I gotta be straight with you – it’s a bit of a slow burn for the first week and a half, but there’s a little glimmer of hope way out there.
The overall pattern is pretty quiet. We’re looking at a long stretch of small, weak swell with choppy, cross-shore winds that are just going to mess things up. The early days are a real write-off. For the first ten days, there’s nothing that’s going to get you out of bed. We’re talking about a gap of nearly a week and a half with no real surf to speak of.
Wednesday morning, the 2nd, offers a tiny bit of east swell at 1.6ft, but it’s only got a combined energy of 63 (weak). The cross-off wind will keep it clean, but it’s just too small and ordinary. After that, it's a straight-up run of poor surf conditions. Thursday, Friday, Saturday, Sunday... all the same story. Small, weak swells, barely 1.3ft to 2ft, and the wind is either cross or cross-on, turning the surface into a washing machine. The afternoon of Saturday the 5th sees a bit of a bump to 4.3ft, but it’s a fresh 30 km/h cross-wind, making it lumpy and nasty. Sunday morning the 6th is clean with a cross-off breeze, but it’s still only 2.6ft and weak (55 energy). The following week is more of the same – small, messy, and frustrating.
Now, the lone standout. It’s a long way off, but Sunday morning, the 13th of September is the one to circle on the calendar. We’ve got a solid 4.6ft east-northeast swell coming in with a period of 8 seconds. That’s a moderate energy (237) and it’s building. The real kicker is the glassy, flat-calm conditions – wind at 5 km/h from the east. That’s a total score for clean, lined-up waves. The Groyne is a reef break, so a longer period swell like this (8 seconds is decent) will hold its shape and offer some proper waves. The swell direction from the ENE is a good match for the optimum SE direction here, so it should wrap in nicely. Keep in mind, this is a pretty consistent spot, so you won’t be waiting forever. But with a 4.6ft swell, it’s still in the beginner-friendly range, so it won’t be too heavy.
The water is currently a bit chilly, sitting at 68.4°, which is 1.8° colder than normal for this time of year. The morning of the 13th will be a bit of a gamble, but the potential is there for a really fun session. The following Thursday morning, the 17th, also has a similar 4.6ft ENE swell, but the wind is a cross-shore, which is not as good as glassy. The 13th is the clear winner.
Stay tuned, and keep an eye on the forecasts. Until next time, get some.

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.
