The Lowdown

Alright, Rusty here again. Let’s look at the same picture, but in feet and miles per hour.

This 16-day window is looking pretty slim for The Groyne. It’s a reef break, and it’s going to be a battle with the wind for most of the time.

The only real chance of a decent wave is on Wednesday morning, the 2nd of September. The wind goes glassy – that’s a huge plus. The swell is from the ENE at 4 feet, with a period of 8 seconds, and the combined energy is moderate at 203. The report says “expect good surf conditions,” which is the one bright spot. The water temp is about normal for this time of year.

After that, it’s a long, dry spell. The wind is onshore or cross-shore for days on end. The swell runs between 1 feet and 5 feet, with periods mostly under 8 seconds. The combined energy drops to low numbers like 28 (very weak) and 57 (weak) by the 10th of September. There’s a bit of cross-off wind on the 8th of September, but the swell is only 3 feet with a weak energy of 86 – not worth the effort.

The gap between the decent session on the 2nd and anything else is huge. You’re looking at a gap of over a week from the 2nd of September right through to the 10th, but even the 10th is just a flat, glassy morning with a tiny 1-foot swell and energy of 28 – not surfable. The 7th of September has some swell, but the wind is cross-on and choppy.

For a beginner, the 4-foot swell on the 2nd is fine, but the main enemy here is the wind. The constant onshore flow will mess up the surface. The only standout is that one glassy window. If you’re a local, you know the deal – you have to be ready to go when it’s on, because it doesn’t stay good for long.

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.
