The Lowdown
Alright, folks, Rusty here. Let's break down what's on the table for The Groyne over the next couple of weeks. Straight up, it's not a classic run – the first few days are a write-off with strong onshore winds and lumpy, messy surf. The swell shows up, but the wind just won't play ball. We do get a couple of short windows where things clean up, but don't expect any magic.
We kick off Saturday 18 July with some solid swell – 7.5ft to 8.2ft from the SE, period around 10 seconds, moderate energy (1294 on the afternoon). The wind is cross-off in the afternoon, so the surface cleans up, but the overall forecast calls it marginal – likely tide issues. Crowds are possible, so if you're keen, that afternoon slot might be the biggest wave you'll see, but it's far from perfect. Water temp sits at 68.9°, pretty normal for this time of year.
Then it goes downhill. Sunday 19 through Tuesday 22 are all poor – strong cross-onshore winds, messy, chop. Swell drops from 11.5ft down to 5.2ft, but the wind just ruins it. Wednesday 22 afternoon has a light cross-on breeze with 4.6ft E swell, but it's only marginal.
Now, the real highlight – and I mean the only one worth setting an alarm for – is Thursday 23 July morning. The wind goes glassy, dead calm, with 3.3

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.
