The Lowdown

Alright, Rusty here. Let's get into it.

Honestly, the next week or so is looking pretty frustrating for The Groyne. We’ve got a long stretch of small, weak, and messy conditions. The first real chance of a wave doesn't show up until Wednesday morning, September 2nd, and even then it's a small, clean little knee-high wave. We’re talking about a combined swell energy of just 67, so there’s nothing with any punch. The water temp is about average for this time of year, nothing unusual there.

Things don't really improve. The action kicks off a bit on Wednesday morning, September 9th. We get a glassy morning with a bit of a bump from the SSE, pushing 1.4m (about 5 ft). The combined energy hits 131, so it's not a lot, but the glassy conditions will make it look better than it is. After that, it gets a bit wild. By Thursday the 10th, we see a big jump in swell size, but it's onshore and messy. The standout period, if you can call it that, is the morning of Saturday, September 13th. We’ve got a 2.0m (7 ft) swell from the ESE, period around 9 seconds, and a combined energy of 576. The wind is gentle cross-onshore, so it’ll be fairly choppy, but it's the biggest, most consistent window in the whole outlook. The swell direction is coming from the ESE, which is a bit off the optimum SE for The Groyne, but it's the best we’ve got.

For the purists, Wednesday morning September 9th offers the cleanest conditions, but the waves are small. The biggest surf comes in on the 13th, but it's a bit lumpy. If you're an expert, the big, raw energy on the 10th and 11th is too onshore and messy to be any good. This spot is a reef, so it handles swell direction better than a beach, but even then, the onshore winds ruin it.

Overall, it's a flat start, a few tiny windows, and a messy finish. The period from the 2nd to the 8th is mostly a write-off, with nothing worth paddling out for. The best bet is to keep an eye on that Saturday the 13th.

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.
