The Lowdown
Right then, let’s have a look at what’s on the cards for the next couple of weeks. To be honest, it’s a bit of a tough stretch ahead. The only break that’s on the radar is The Groyne, a reef setup, and it's not exactly playing ball for the most part. We’re looking at a solid run of days where the wind and conditions just aren’t coming together for a proper paddle session.
The Groyne is fairly consistent in terms of swell arriving, but the wind is the real story here, and it’s not a good one. We’ve got a long stretch from Friday the 17th right through to the end of July where onshore and cross-onshore winds are the norm, keeping things messy and lumpy. The swell itself is there, with some decent size, but it’s all short-period, wind-affected stuff. The energy is moderate to strong, hitting over 1500 (combined energy of all swells directed here) on Sunday and Monday the 19th and 20th, with swell heights around 10ft, but it’s coming from the ESE with a short period of 9-10 seconds, and it’s being blown apart by 18-22 mph winds. That’s not surfable; that’s a washing machine. For the first week, it’s mostly a write-off for a decent paddle.
The first real glimmer of a chance comes on Saturday the 26th of July. The morning looks the pick of the whole outlook. We’ve got a light SSW wind, just 3 mph, blowing cross-offshore, which should clean things right up. The swell is small, only 3ft from the east, with a period of 7 seconds, and the energy is weak (89). It’s not going to be big or powerful, but it’ll be clean and glassy, and that’s a rare treat in this forecast. The break is inconsistent, so you’ll be waiting for sets, but when they come, it’ll be your own little clean session. The water temperature is about 69°, which is a touch below the average for this time of year, nothing crazy.
After that, the waves drop away quickly. By Monday the 27th, we’re down to 2ft, and by Tuesday the 28th, we’re looking at near-flat conditions with 2ft and glassy conditions in the morning, but it’s just too small to be worth a drive. The offshore winds continue on the 27th morning, but you’re chasing tiny, weak waves.
Looking into the first week of August, there’s a bit of a pulse. On Saturday the 1st of August, we see a small swell from the SE, 4ft with a 6-second period. The kicker is the wind: a light WNW, 9 mph, blowing offshore. That’s a solid turn-around. The energy is still weak (134), but with clean, offshore lines, it’s a much better prospect than anything we’ve had. It’s still a long way out, so don’t lock it in, but it’s the one to keep an eye on.
Overall, it’s a lean period. The highlights are the glassy morning on the 26th of July for a tiny, clean session, and the promising offshore morning on the 1st of August. If you’re a beginner, the swell never gets over 5ft during the clean windows, so it’s safe. For anyone else, patience is the name of the game.

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.
