The Lowdown
Alright, let's get into it. Rusty here, looking at the forecast for The Groyne.
First thing’s first, we’ve got a slow start. The week ahead is pretty much a write-off for anything decent. We’ve got a big, powerful swell coming in on Sunday the 19th, with a massive 3525 (combined energy) of SE swell, but it’s hitting 13ft with a strong 28 mph cross-shore wind. That’s a total mess – strong cross-shore with messy cross-chop. It’s not surfable, that’s a kite day if anything. The water temp is at 69°F, which is about average for this time of year, nothing to write home about there.
Monday and Tuesday are more of the same; the swell is still solid but the wind is onshore or cross-onshore, keeping it choppy and lumpy. The swell drops a bit through the middle of the week, but it’s still not clean enough to get excited about.
The first real glimmer of hope comes on Thursday morning, the 23rd of July. We’ve got a clean 4ft swell from the east with a light offshore wind from the WSW. The period is a short 8 seconds, so it’s not a groundswell, but the conditions will be clean. The energy is down to 216 (combined energy), so it’s a weak, small wave. It’s a surfable option, but it’s not a standout.
The real standout, the best of the whole 16-day window, is the following Saturday morning, the 25th of July. The swell is a bit smaller at 5ft from the SE, but the wind is light and offshore from the SW, which will make it clean. The period is a very short 7 seconds, so it’s a windswell, but the clean conditions on a reef break will make it rideable. The combined energy is 394 (moderate wave energy). This is the best we’ve got on offer.
After that, the surf drops off a cliff. From Sunday the 26th right through to the end of the forecast on August 3rd, the swell is tiny, mostly under 3ft, and the energy is weak. There are a few mornings with offshore winds, but there’s simply no swell to work with. It’s a long, flat spell.
So, to wrap it up: don’t bother with this week. The Thursday morning (23rd) is a small, clean option, but the real call is for next Saturday morning, the 25th of July. Get out there early for a clean, small wave on the reef. The Groyne can get crowded sometimes, so keep that in mind. After that, the board goes back in the bag for a while.

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.
