Table - best surf conditions forecast for The groyne over the next 16 days.
Alright, Rusty here. Let's break it down.
Things are looking pretty bleak for a while at The Groyne. We've got a long stretch of poor to ordinary conditions ahead, so don't be in a rush to paddle out. The first real glimmer of hope doesn't come until Monday the 20th, that's over a week away. For a solid week before that, you're looking at flat spells, howling cross-shore winds, and some serious lumpy, messy surf. The best bet is to sit this one out.
The one true standout in this whole 16-day window is the morning of Monday the 20th. The swell will be a solid 8 ft from the ESE, carrying a fair bit of grunt with a raw energy reading. That's moderate to strong energy. The period is 11 seconds, so there's some decent shape to it, but on a reef setup like this, that should be fine. What really makes this session is the light offshore wind from the SSW, keeping things clean. The sets will be solid; this is for experienced surfers only as it's well over the 5 ft mark. It's the only session in the entire forecast that gets a big thumbs up for quality.
Leading up to that, the Thursday, Friday and Saturday before (the 16th-18th) are completely out of the question for a paddle board. We're looking at strong SSE winds over 18 mph, pushing a big, lumpy 10 ft cross-onshore swell with period between 8 and 11 seconds. The wave energy spikes hard, hitting massive readings on the 17th, but it's completely blown out and dangerous. Honestly, with that setup and a beach-and-reef configuration, this might be more appealing to the kite crew than anyone with a paddle.
After that Monday morning peak, the surf hangs around but the quality drops. The wind switches around, and the conditions become more marginal through Tuesday the 21st and Wednesday the 22nd. The swell drops, and you'll have some cross or side-off winds, but the tide and conditions will need to be perfect. Nothing else in the second week makes the cut.
So, mark your calendar for Monday the 20th. The rest of the time? Save your energy. The water temp is sitting around 69°, which is about average for this time of year, nothing unusual 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.
