The Lowdown
Alright, mate, Rusty here again, same story but in feet and degrees Fahrenheit.
First week is a total bust. From Monday July 27th through to the end of that week, you’ve got hardly any surf – tiny waves, onshore or cross winds, and weak energy. Swell height is barely 0.6ft to start, and even when it bumps up a bit, the period is short (5-6 seconds) and the wind is messy. Combined energy readings are low, like 28 to 55, meanin’ it’s all fluff. Not worth wettin’ the suit.
Into early August, the size starts to come up but the wind stays average – cross or cross-onshore – and conditions remain poor or marginal. You get some moderate energy (265 to 528) on the 5th and 8th, but the period is still short and the wind chops it up. Still no good.
The real window opens Monday August 10th. Monday morning the swell jumps to 8ft from the SE with a 10-second period, and the combined energy rockets to 1923 – that is serious power. Wind is a gentle cross-shore, so it’s not glassy but it’s workable for experienced blokes. At that size, this is experts only. The groyne is a reef, so the longer period should give some shape, but it might close out. This is the biggest day of the whole run.
Then Tuesday August 11th morning – glassy. Wind from the SW, barely a breath. Swell holds at 6ft from the east, 10-second period, combined energy 740. That’s your cleanest, most user-friendly day. Lines will be clean, chest-to-head high, proper waves. Crowds can show up (sometimes), so get in early.
First week and a half is a dud. The second week has the only real standouts: Monday for the big stuff (experts only) and Tuesday morning for clean fun.
Water temp is 68°F, which is a bit below the usual for late July – about 2° cooler than average. Not drastic, just a little brisk.
Rusty out.

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.
