Right, let’s have a look at what the next couple of weeks are shaping up like for the local stretch. I’m not gonna lie to ya, this is a tough run. We’re going to see a long, quiet spell with very little to get excited about. The Groyne is the only break on the cards here, and it’s a reef setup that’s fairly consistent, but the conditions are going to fight us almost every step of the way. The water’s running at about 69°, which is a fair bit cooler than usual for this time of year – nearly two and a half degrees off the mark – so you’ll want a decent spring suit.
Starting off on Saturday the 4th of July, it’s a write-off. Small, messy swell with a cross wind, just poor surf. Sunday the 5th and Monday the 6th are the same story – onshore winds and lumpy, weak lines. The swell does bump up on Monday afternoon, hitting 8 ft from the SE, but it’s short-period windswell at just 7 seconds and the wind is all wrong. That’s too much juice for beginners anyway, and the quality is garbage. Things stay pretty average right through until Wednesday the 8th of July. That morning we get a little flicker of hope: 6 ft of SE swell with a longer period of 11 seconds, giving us a moderate wave energy of 882. It’s a groundswell, which is good for a reef like The Groyne, but the wind is still cross, and they’re calling it marginal at best. Honestly, not worth paddling out for.
From there it fades hard. The rest of that week and into the next is a total doldrum. Thursday the 9th through to the end of the following week sees the swell drop to barely a ripple, with combined energy readings in the double digits and single digits. There’s a morning on Saturday the 11th of July where the wind goes cross-off and light, but the swell is only 3 ft and the energy is weak (147). It’s surfable, but ordinary. Sunday the 12th of July is much the same – tiny 2 ft SE swell, though the wind goes light from the NNW (cross-off). Clean but gutless.
Finally, after a long, dry run, we get something to aim for on Sunday the 19th of July. The afternoon sees a jump to 6 ft of SSE swell with a period of 10 seconds and some serious energy behind it – 1030. That’s the standout in the whole forecast. The wind is light from the SSE, putting us in a cross position at The Groyne. It’s not perfect, but it’s the best we’ve seen in weeks. It’s a solid size, so this one’s for the experienced crew – beginners will find it a handful. The direction is a touch south of the optimum SE, but with that much energy and a clean-ish wind, it could still produce some fun ones.
Everything before that is a gap of more than a week with nothing worth chasing. Keep an eye on that Sunday the 19th though; it’s a long way out, so treat it as promising but not locked in.

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.
