Alright Rusty here. Let’s look at what we’ve got.
To be straight with you, this forecast is a challenge. For The groyne, we’re looking at a long stretch of nothing good. From Saturday, July 4th, all the way through the next week, the wind is just a constant problem—cross and cross-on breezes at 12 to 19 mph, tearing up every surface. The swell energy, while moderate to strong (up to 664), gets ruined. Water temp is about normal for this time of year.
The only real highlight, and it’s a long way out, is Sunday, July 12th. Early that morning we’ve got a light offshore wind from the WNW at 3 mph and the wind state is glassy. The swell is a tiny 0.7m (2 ft) from the ESE with a long period of 11 seconds, which is a groundswell—good shape, but it might need a reef or point to work its best. The energy’s moderate (195). It won’t be big, but it’ll be the only clean session. Crowds can pop up here sometimes.
Then on Monday, July 13th, another glimmer: a 3 mph offshore from the WNW, 0.7m (2 ft) ESE swell (period 10 seconds), and a clean water surface. It’s weak energy (90), so it’s strictly small-wave gear.
After that, from July 14th through the 19th, it’s tiny or blown-out again. There are days with swell over 1.5m (5 ft)—like the 2.0m (7 ft) on Saturday the 18th—but with a cross-on 12 mph wind, it’s all just lumpy chop. Better for kiting than surfing.
Bottom line: if you want a wave, Sunday, July 12th morning is your only real bet. Everything else is a skip.
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.
