The Lowdown
Alright folks, Rusty here. Let’s break down what we’ve got for the next couple of weeks.
Honestly, you can scratch the first few days. We’ve got a dry spell with no real surf until Tuesday morning, August 4th. The weekend and Monday are just a blown-out mess of onshore wind and junk.
Your first chance to paddle out comes Tuesday morning, the 4th of August, at The groyne (reef). It’s not going to blow your mind, but it’s the start. You’re looking at a tiny 2ft swell from the SE, with a period of 9 seconds. The juice is weak (116). The huge win here is the wind – it’s glassy. That means the surface will be smooth as butter, even if the waves are small. For a beginner, this is perfect. The water temp is about average for the season.
Wednesday the 5th is a step up. The morning offers a 3ft swell from the east (10-second period, moderate energy at 167) with a light cross-offshore breeze from the SW, keeping it clean. The afternoon turns glassy again, but the swell period drops to 8 seconds, making it weaker (122). It’s surfable, but nothing special.
The standout session, and the best of the whole forecast, is Tuesday morning, the 11th of August. The groyne should have a 2ft swell from the SE, but with a very long period of 12 seconds. That’s real groundswell. The energy is moderate (198). The kicker is the glassy conditions with a light offshore wind from the NW. Since it’s a reef, that long-period energy will wrap in nicely and hold up. It’ll be clean, and the long lulls will make it easy to get in position. Crowds are possible.
The rest of the second week is a story of onshore wind. Wednesday morning the 12th is clean with a cross-offshore breeze and a 3ft, 11-second ESE swell (179 energy), but that’s the last decent one. From Thursday the 13th onward, the wind gets nasty, with fresh breezes up to 21 mph. The swell is actually there, with some solid energy (267-415) and long period, but the wind will tear it up. This stretch is for the kite and windsurf crowd.
So, here’s the plan: skip the start. Tuesday the 4th is a tiny, clean option for beginners. Wednesday the 5th is a little better. But the one to mark on your calendar is Tuesday morning, the 11th of August – clean, glassy, long-period groundswell at The groyne.
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.
