The Lowdown

Alright, surfers, Rusty here. Let’s be straight with you. The next couple of weeks around The Groyne are looking pretty grim, if I’m honest. There’s a lot of chop, a lot of onshores, and not a lot of quality. We’re going to have to pick our moments carefully, and even then, it’s all about managing expectations.

The water’s sitting at 68°, which is about 1 degrees cooler than usual for this time of year. Not a huge deal, but you might want a spring suit if you’re sensitive to that sort of thing.

The window kicks off with a small window on Wednesday morning, August 5th. It’s not much – ankle to knee-high, maybe thigh-high at best, with a weak 3ft of east swell. The wind is glassy though, which is something. It’s clean, and The Groyne (Jersey) is a reef, so it might have a bit more shape than a beachie, but with that energy so weak at 170, it’s just a dribble. You’re only going to get a few little shoulders on a longboard. By afternoon, the wind swings onshore and it’s messy.

The rest of the first week is a write-off, honestly. Thursday and Friday have a bit of swell, but the wind is all over the place – cross-off, then straight onshore. It’s small, weak, and bumpy. Saturday is cross-shore and junky. We see a bit of clean glass again on Sunday morning, August 9th, with the swell picking up slightly to 3ft and the energy rising to a moderate 209. The period is a bit better at 9 seconds too. That morning is going to be the best of the first week. It’s not big, but it will be glassy and clean on that reef. After lunch, the seabreeze comes up and ruins it again.

There’s a bit of a lull for a few days after that, with nothing really worth paddling out for until the following week. The energy stays moderate and the winds are messy, mostly cross-off in the mornings, but the swell drops right off.

Now, looking into the second week, things get a bit more interesting, but it’s not good news. Starting from around the 13th, we see a pulse of swell arrive, but it’s coming from the SE and the wind is just on it, or cross-shore at best. There’s a bit more size – up to 6ft on Sunday the 16th – but the period drops right off to 6-7 seconds. That’s just windswell, and with the cross-onshore winds, it’s going to be a complete mess. All that energy, 290 on the 16th, is just going to be lumpy, close-outy, and generally horrible. This isn’t surf for paddling; with that wind and chop, it looks like a kite-surfing setup if anything.

There’s another pulse of energy on the 20th, with the reading hitting a strong 420, but again, it’s a 4ft SE windswell with cross-shore winds. The period is a bit better at 9 seconds, but it’s still going to be a jumbled-up, cross-chop mess.

So, in short, the standout window is that Sunday morning, August 9th. It’s not big, but it will be the cleanest, most playful surf we get. If you miss that, you’re waiting a long time for anything worth getting wet for. Everything after that has size but no shape, and it looks more like a battle than a session.

Keep an eye on it, forecasts change, but as it stands, be patient. It’s not looking good for a while.

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.
