The Lowdown

Alright, let’s have a look at what’s coming up for The Groyne.

Honestly, the next couple of weeks are a mixed bag. We’ve got some surf on the cards, but a lot of it is going to be ordinary or just plain messy. The best bet looks like it’s going to be the morning of Tuesday the 25th, and then we might get a bit of a window right at the start of September, but don’t hold your breath.

Saturday the 22nd kicks things off with a small 3ft east swell, period around 7 seconds. It’s clean enough in the morning with a light cross-off wind, but the wave energy is only moderate (105). The afternoon stays similar, still just ordinary.

Sunday the 23rd and Monday the 24th are a write-off. The swell drops a touch to 3-3ft, but the wind swings cross and cross-onshore, making it choppy and poor. Not worth paddling out.

Tuesday morning the 25th is the standout for the first week. The swell bumps back up to 3ft from the ENE, still with an 8-second period, but the wind goes glassy. That means clean, smooth conditions. Wave energy is moderate (155). It’s small, but if you want a fun, uncrowded session on a reef break that’s fairly consistent, this is your window. The water temp is about average for the time of year.

After that, the wind turns against us from Wednesday through the rest of the week, with cross and onshore winds ruining the shape. The swell does build a little, hitting 5ft on Thursday and Friday mornings, but it’s coming with cross-shore winds and marginal conditions. Not great.

Saturday the 29th and Sunday the 30th are still messy. The swell tries to hold around 4-5ft, but onshore and cross-onshore winds keep the surface lumpy.

Now, looking into the first week of September, things get a bit bigger but still tricky. Monday the 31st and Tuesday the 1st are blown out with fresh onshore winds and swell around 4-6ft. The wave energy gets moderate to strong (up to 457), but the wind is a problem.

Wednesday morning the 2nd of September is the other one to keep an eye on. We’ve got a 6ft east swell with a 7-second period, and the wind is light and cross-shore. The energy is strong (521), but the period is short, so it’ll be a bit bumpy and crumbly. Still, it’s the best-looking swell size of the whole outlook. The afternoon gets smashed by a strong cross-onshore breeze, so get it early.

The rest of the first week of September is mostly poor, with onshore winds and rain. Friday morning the 4th does offer a clean 5ft ENE swell (499 energy) with a 9-second period and a light cross-off breeze. That’s a solid, clean option if you can get out before the wind shifts.

After that, it drops off fast. Saturday the 5th has a tiny 3ft swell with an offshore wind, but it’s very weak. By Sunday the 6th, the swell is gone, down to 2ft.

So to sum it up: the best windows are Tuesday morning the 25th of August for clean small waves, and then Wednesday morning the 2nd of September for some size, but it’s short period and gets messy fast. Friday morning the 4th of September is another decent, clean option if you’re patient.

Keep your expectations in check, but there are a few fun sessions to be had.

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.
