The Lowdown
Righto, gather 'round. Rusty here, and I've been staring at the charts for The Groyne. Let's be straight with each other – it's a bit of a rough stretch ahead. The Groyne is a reef setup, works best with a solid SE swell, but we're looking at a long, dry spell before anything half-decent shows up.
The first week and a bit is a write-off. From Thursday the 16th right through to the 22nd, it's a mess. We've got a solid SE swell coming in, but the wind is just no good. It's cross or cross-onshore, and the whole thing is lumpy, choppy, and messy. The wave energy is all over the place, from moderate up to very strong on the 20th, but with that wind, it’s just a washing machine. Forget about it. There's a bit of a gap here with no real recommendations for days.
The light at the end of the tunnel comes on the morning of Thursday the 23rd of July. That’s the first time we see "clean" in the report. A light cross-offshore wind from the SSW, with a 5ft SE swell, period around 8 seconds. The energy is moderate. For the first time, it looks genuinely surfable and clean. It’s not a standout for the ages, but after the junk we’ve had, it’s a welcome sight. The water temp is about 69°F, which is pretty normal for this time of year.
Friday the 24th of July morning also looks okay with a 4ft swell and clean conditions from a cross-offshore SW wind, but the swell is a little smaller. The standout here is definitely that Thursday morning session. Saturday the 25th morning is clean but small, with a 4ft SE swell. After that, it all drops out again, with minimal energy and poor conditions through to the end of the month. The last few days of July and into August are small, weak, and mostly cross-onshore again. There’s a final flicker on the 30th with a clean 5ft SE swell, but the energy is weak, so it's ordinary.
So, in a nutshell: wait for the morning of Thursday the 23rd of July. That’s your best bet. The rest is a long, slow grind. Hang in there.
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.
