Table - best surf conditions forecast for The groyne over the next 16 days.
Alright crew, Rusty here. Let’s break down the next couple of weeks.
The main spot to talk about is The groyne, a reef break that usually handles swell well. The water is sitting at 69°F, which is a bit cooler than normal for this time of year.
The real standout is Saturday morning, 11 July. We’ve got offshore wind and clean conditions. The swell is 3ft from the SE, with a period of 11 seconds, giving it proper shape. The combined energy is moderate (231). It’s not jacking, but it’ll be clean and fun. Just a heads up, crowds are possible, so be ready to share.
Friday morning, 10 July, has a bit more size at 6ft from the SE, but the cross-shore wind and chop ruin it. The energy is strong (1062), but the quality is poor. For beginners, 6ft is too big, especially with the mess.
From Sunday 12 July through to Wednesday 15 July, the surf flatlines. We’re looking at tiny waves and weak energy (under 100). A gap of several days with nothing really worth paddling for.
We get a small pulse on Thursday morning, 16 July, with a 5ft SE swell, but the period is a short 8 seconds, so it’ll be a bit sloppy. The wind is cross-offshore, keeping it clean, but it lacks push. The energy is moderate (267).
Then the wind goes nasty. Friday 17 July and Saturday 18 July have 6ft from the SE, but with strong to near-gale cross-shore winds, it’s a total mess. This is more of a kite-surfing setup than a paddle-surfing one.
The second week, from 20 July onward, is tiny. A few mornings on 22 and 23 July show clean, offshore winds with waves around 2ft, but the energy is weak. Not worth a special trip.
So, the call is: Saturday morning, 11 July is your best shot for clean, fun waves. The rest of the forecast is mostly small, windy, or both.
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.
