The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for The Groyne. To be straight with you, it’s looking like a real quiet stretch ahead. The first surfable swell isn’t for a while, so we’ve got a bit of a wait on our hands.
The opening days are a non-event. The wave energy is weak, with combined swell energy barely getting into double digits – we’re talking readings like 17 (Saturday morning) and 20 (Sunday morning). The swell is tiny, around 1.0ft to 2ft, and the wind is all over the shop, meaning the small bumps are chopped up and messy. There’s nothing to get excited about, and the conditions are poor.
We finally get a glimmer early on Monday the 7th. The morning shows a glassy surface with the wind coming from the East at just 3 mph. The swell is still a meagre 2ft from the NE with a short period of 8 seconds, and the energy reading is only 67. It’s surfable, but just barely. The afternoon turns back to junk with a cross-onshore wind.
The pattern doesn’t improve much. We get a few more mornings with glassy conditions, like on Thursday the 4th and Monday the 14th, but the swell is just too small to offer anything worthwhile. The energy remains weak, always under 100.
The one event that stands out, and it’s a real maybe, comes on the afternoon of Monday the 14th. The swell jumps to 4ft, which is a bit more size, but it’s coming from the NNE with a pitiful period of 5 seconds. The combined energy spikes to 184 (moderate energy), but with a 5-second period, it’s going to be a crumbly, weak mess. The wind is a cross-onshore at 9 mph, so it’ll be choppy and messy too. This is really only for the most dedicated, and even then, it’s a stretch.
The very end of the forecast window, on Sunday the 13th and Monday the 14th in the mornings, has some clean, glassy conditions with a tiny 1ft swell from the SE. The period is a decent 11 seconds, which is a long-period groundswell, but the size is just too small for it to do anything proper at the reef. The energy is still weak.
So, what’s the best on offer? Honestly, there isn’t a standout. If you absolutely have to get wet, the glassy mornings on the 13th and 14th with the 1ft, 11-second swell offer the cleanest conditions, but you’ll be scratching for anything to ride. The 4ft on the 14th afternoon is the biggest, but it’s a poor-quality, short-period, choppy windswell. It’s a tough run.
The water is a bit colder than normal for this time of year, sitting at 68°.

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.
