The Lowdown
Alright crew, Rusty here again. Let's look at what The Groyne has in store.
This reef break is in for a rough few days, so don't bother paddling out until later in the week. We've got a decent pulse of swell on Monday July 20th and Tuesday July 21st, with chest-to-overhead sets, but the wind is a nightmare. Strong cross-onshore winds from the southeast are going to ruin the surface, creating choppy, lumpy conditions. The wave energy is strong at 2733 on Monday morning, but it's not worth the hassle.
Things improve slightly on Wednesday July 22nd. The swell drops to around 5 to 6 feet from the east with a 9-second period. The wind eases to a light breeze, but it's still cross-onshore, leaving small wind ripples on the surface. The conditions are still marginal.
Here's the one you've been waiting for. Thursday morning July 23rd is going to be firing. The wind goes glassy, a light offshore from the southwest, cleaning up a 4-foot swell from the east with an 8-second period. The wave energy is low at 204, but with those perfect, clean conditions you'll be getting some fun little waves. This is the best of the bunch, and expect to share the lineup with others.
After that golden window, the surf drops. Friday July 24th and Saturday July 25th are a mix of small, weak swells and poor winds. Saturday morning has some clean but tiny 3-foot waves with a cross-offshore breeze, but the energy is weak at 112. It's surfable, but nothing special.
Heading into the second week, from July 27th, it's mostly flat. The swell all but disappears, with wave heights barely hitting 3 feet and messy winds. There's a tiny blip on July 31st with some 2-foot groundswell from the southeast, with a long 14-second period. The wind is light and cross-offshore, making it clean, but it's very small. The wave energy is only 134.
Bottom line: don't get your hopes up. The first week has one decent, clean morning on the 23rd. The second week is a flat spell with just one day of tiny, clean waves. If you're into kiting, those windy days earlier in the week might interest you more than the paddle surfing.
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.
