Righto, grab a seat, let’s talk surf. The Groyne (The-groyne_1) is sitting there, and over the next couple of weeks, it’s a bit of a mixed bag. The water temp is pretty average for this time of year, nothing weird going on there.
You’ve got a real dead patch to start off. Thursday the 9th and Friday the 10th are basically a write-off – messy cross-shore winds and poor quality surf. Saturday the 11th morning shows a glimmer though. Swell drops to a knee-high 3 ft from the SE, period around 11 seconds, and with a light S breeze, it goes cross-offshore, leaving the place clean. The energy is weak (231), but it’s the best you’ll see for a few days. It’s not a standout though, just a little session if you’re desperate.
Things stay flat-ish and ordinary through Sunday and Monday the 12th and 13th. Then there’s a real lull from Tuesday the 14th right through to Wednesday the 15th – tiny, barely anything.
Now, here’s the bit that gets the blood going. Late in the outlook, on Saturday the 18th afternoon, we see a proper pulse. Swell jumps to a solid 7 ft from the SE, with a moderate 10-second period. The kicker is the wind – light cross-offshore from the SSW – and the combined energy hits a strong 1266, the biggest reading in the whole forecast. That’s “excellent surf conditions for experienced surfers” territory. This one is the clear standout: clean, decent power, and well over the 5 ft mark, so it’s for the competent crew only.
After that, Sunday the 19th morning is still surfable but dropping fast, and then it fades again into tiny, weak dribble through the following week. The window from the 23rd onwards looks flat again. So, for my money, the one to circle on the calendar is that Saturday the 18th afternoon.

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.
