The Lowdown

Alright folks, this is Rusty, and I’m looking straight at the charts for The Groyne. Honestly, it’s a rough start to the outlook. We’ve got a solid run of proper swell on the way, but the wind is just going to tear it up for days. It’s a real shame.

The first real opportunity doesn’t show up until Thursday morning, the 23rd of July. For a while there, it’s just a mess of fresh cross-onshore winds and lumpy, choppy surf. The swell is there, but it’s unsurfable. The wait is about three days of that junk before we get a window.

That Thursday morning, the 23rd, is the standout of the whole period. The wind drops right out, going glassy, and we’ve got a clean 4ft wave from the east. The water temp is sitting at 69°, which is about normal for this time of year. The combined energy is moderate at 205. It’s a short period swell at 8 seconds, so not a ton of grunt, but with that glassy surface, it’ll be the cleanest little waves you’ll find. It’s the only real highlight in the first week.

After that, things get messy again. The wind swings back onshore or cross-shore, and the swell drops off into the tiny stuff into the end of July. There’s a long gap of poor-to-ordinary conditions, with a few mornings of clean-ish air but hardly any swell to ride.

Now, looking way out to Monday morning, the 3rd of August, we get a bit of a pulse. The swell picks back up to 5ft from the SSE, and the wind goes glassy again. The period is a short 6 seconds, so it’ll be a bit lumpy and weak, but combined energy is moderate at 196. It’s promising, but it’s a long way off, so don’t book the trip yet. That’s the best of the second week.

Tuesday morning, the 4th, looks dead flat again with no wind, so not much to get excited about there.

Overall, it’s a frustrating outlook. The best bet is to be on the water at The Groyne on Thursday morning, the 23rd of July, for that glassy session. The rest of the time, you’re better off waiting for the forecasts to change.

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.
