The Lowdown
Alright folks, it’s Rusty here. It’s a quiet patch ahead for The Groyne right now. There’s a real gap in the action for the first few days; Thursday and Friday are pretty ordinary, with small, weak swell and onshore or cross-off winds making a mess of things. The energy is just not there, with readings under 110 (weak) for the first couple of days. Saturday’s morning session is a bit better, but still small and average. We’re looking at Sunday morning, the 9th of August, as the first real highlight. The Groyne will see a clean 3 ft of east swell, with a period of 9 seconds providing a bit more shape. The wind is glassy, and the combined energy is moderate at 257. It’s not a big day, but it’ll be fun and clean. Water temps are about average for this time of year, nothing unusual to report. The Groyne is a reef break, fairly consistent, and it can get crowded sometimes, so keep that in mind if you’re heading out for that Sunday morning glass-off.
The following week starts to get interesting, but it’s not without its issues. Monday morning (10th) sees clean 3 ft waves with a moderate offshore breeze, but the energy is a bit weak. Tuesday and Wednesday mornings are tiny and glassy, but just not enough push. Then things get a bit hectic around the 13th of August. A big pulse of swell hits on Thursday morning, 13th August, with 6 ft of short-period SSE windswell (6 seconds), but the wind is cross-off and the energy is strong at 367. The surf is marginal, and it’s not clean. By Friday, 14th August, the swell is still solid at 6 ft from the SE, 10-second period, with strong energy (674), but the wind is cross-shore and messy. The real standout in this second week, if you’re an expert, is Saturday morning, 15th August. We’re looking at a big 13 ft of SE swell with an 11-second period, and the combined energy is a massive 5339. That’s a serious amount of power. However, the wind is cross-shore and it’s a rain shower day, with marginal conditions. The period is long enough to have some proper groundswell character, but it’s a big, powerful wave that’s only for experienced surfers. The rest of that weekend and into the next week is a messy mix of big, onshore swell and poor conditions, with the swell dropping off through the 20th and 21st.
If you’re a kite surfer, the whole period from the 13th to the 18th of August has strong, consistent cross-shore winds and solid swell, which looks way more interesting for a kite than a paddle.
The best bet across the whole 16 days is the clean, glassy 3 ft of east swell on Sunday morning, 9th August, at The Groyne. It’s the only time the stars truly align for a clean, fun session. The big swell on the 15th of August is a standout for power, but only for the experts who can handle the rough conditions.

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.
