The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
To be straight with you, the outlook for The groyne is a bit of a tough one. We’ve got a long stretch of poor-quality surf ahead, with the first few days looking particularly messy. The wind is mostly cross or cross-onshore, and the swell is short-period stuff that’s not doing us any favours. The combined energy is moderate for the first couple of days, reaching 230 (moderate wave energy) on the Sunday afternoon, but the quality just isn’t there. The water is a bit colder than normal, about 68°F at the start, with a -1.0°F anomaly, so it’s a touch cooler than average for this time of year.
The first real glimmer of hope comes on Monday, 4th August. For the Tuesday morning, the wind swings to a glassy WSW at 3 mph, and we get a tiny 2 ft swell from the east at 7 seconds (combined energy 105 – moderate). It’s small, but clean. The surf report says "surfable waves but very ordinary conditions," so it’s not going to be pumping, but it might be the best chance for a paddle if you’re desperate. Tuesday afternoon, the wind swings back to cross-on and the surf drops off, so make the most of that morning window.
Wednesday the 5th and Thursday the 6th mornings offer a clean cross-off wind, but again, the swell is tiny – 2 ft to 3 ft. The period on Wednesday morning is 8 seconds, so it’s a short, weak wave, and the combined energy is only 92 (weak). It’s clean, but there’s just not enough push to get excited about. The Thursday afternoon gets a bit of cross-on chop again, so it’s back to ordinary.
After that, we go into a real lull. From the 7th of August through to the 11th, the swell drops to 2 ft or 2 ft, and the wind is either cross-on or cross-off, but the energy is low. The Tuesday morning of the 11th looks promising for a brief moment with a clean offshore wind at 12 mph and a 2 ft swell from the east at 9 seconds, but the combined energy is only 52 (weak). The Tuesday afternoon picks up a bit with the wind going offshore and a 2 ft swell at 10 seconds, giving us a combined energy of 131 (moderate). The report says "surfable waves but very ordinary conditions," so it’s not a standout, but it’s the best we’ll see in that second week.
The rest of the second week is a write-off. The swell is 1 ft to 2 ft, the wind is messy, and the energy is weak. The 13th of August afternoon has a period of 13 seconds, which is a long-period groundswell, but it’s tiny at 1 ft and the wind is cross-on, so it’s not going to do anything. The combined energy is 110 (moderate), but with that size, it’s just not surfable.
So, for the standouts, the Tuesday morning of the 4th of August is your best bet for a clean, glassy session, even if it’s small. The Tuesday afternoon of the 11th of August is the other one to watch – offshore wind and a little more energy, but it’s still ordinary. Don’t get your hopes up for any proper waves on this 16-day window, though. The groyne is not really firing right now.
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.
