The Lowdown
Alright, let’s get into it. The outlook for The Groyne is a bit of a challenge, with a long stretch of nothing much to write home about. The water temperature is 68° at the start, which is about a degree colder than the norm for this time of year – a bit nippy, but nothing dramatic.
The first real chance of a surf comes on Thursday morning, the 23rd of July. It’s not huge, with swell around 4ft coming from the east, but the magic is in the wind. We’ve got a light, cross-off breeze from the southwest, so the face will be clean. The combined energy (209) is moderate, and the period is a short 8 seconds, so it’ll be a bit fat and weak, but for a spot that’s been so quiet, this is your best bet. Crowds are possible here, so keep an eye out.
Then we jump to Saturday morning, the 25th of July. Another clean session with light cross-off wind from the south, and swell holding at 4ft from the east-southeast. The energy is a bit higher at 242, but still a short period swell. It’ll be rideable but not punchy.
After that, things get really quiet. There’s a whimper of a swell on Sunday morning the 26th, with 2ft from the east, but it’s surfable at best. Then we’re looking at a big gap of practically nothing for days. A few tiny pulses show up, but they’re all under 2ft and not worth paddling out for.
The next flicker of hope comes on Friday morning, the 31st of July. The swell bumps up to 4ft from the east-southeast, with a light cross-off from the north-northwest, so it’ll be clean. The energy is low (118) and the period is short (5 seconds), so it’ll be messy and weak. It’s surfable, but you’ll be working for it.
The last notable mention is Tuesday morning, the 4th of August. The swell jumps to 6ft from the south-southeast, but the wind is a moderate cross-shore from the south, making it choppy and poor. The energy is moderate (259), but the onshore wind kills it. It’s a miss.
So, the standout here is Thursday morning, the 23rd of July. It’s not pumping, but it’s the best we’ve got. The rest of the window is mostly flat or blown out. A tough run for The Groyne.

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.
