The Lowdown
Alright, let’s get into it. The forecast for The Groyne is a tough one for the next couple of weeks. There’s no surf on the table right now, and it’s going to stay that way for a while.
The first sign of any real swell doesn’t show up until the afternoon of Thursday, 30th July, when a weak 4ft swell from the SE sneaks in, but with a short period of 5 seconds and a cross-onshore wind, it’s just messy. The wave energy is weak (104). It’s not worth paddling out for.
Friday, 31st July, through the weekend, we see a bit more height – around 3ft to 4ft – but the wind stays cross or cross-onshore, and the period is short (6 to 7 seconds). The combined energy climbs into the moderate range (152 to 230), but the surf quality is still listed as poor. Conditions are choppy and lumpy. It’s not looking like fun.
The morning of Monday, 3rd August, sees the swell energy jump to 309 (moderate) with a 4ft swell from the east, but it’s a short-period 7 seconds and a cross-shore wind. The water temperature is about average for the time of year, nothing out of the ordinary.
From Tuesday, 4th August, through to Friday, 7th August, the swell holds around 4ft to 5ft, but the wind is often fresh and cross-shore, and the period remains short. The energy stays moderate, but the conditions are consistently described as poor or choppy. On Thursday, 6th August, the swell hits 5ft, which is getting a bit big for beginners, but with the wind and short period, it’s not a highlight.
The best looking window in this whole 16-day period is the morning of Tuesday, 11th August. The wind goes glassy, the swell is tiny at 1ft from the ESE, and the period is a decent 8 seconds. The energy is weak (41), but the clean conditions are a rare treat. It’s the only real standout, but it’s a small one.
The following morning, Wednesday, 12th August, has a 3ft swell from the east with a solid 10-second period, and a clean offshore wind from the SW, giving a combined energy of 301 (moderate). It’s a promising start to the day, but it’s far out in the forecast, so keep an eye on it.
Overall, this is a long stretch of poor surf. The Groyne is a reef break that needs a decent swell and clean wind to fire, and we’re just not getting the combo. The period stays short all the way through, and the wind is rarely your friend. The glassy Tuesday morning is the only real window for a quiet, small-wave session.

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.
