The Lowdown
Alright, Rusty here. Let’s break down what we’ve got for the coming couple of weeks. Honestly, it’s a grim stretch for most of it. The first real chance for a wave comes in on Thursday the 23rd of July, but it’s not much to write home about. We’ve got small 4ft swell from the east, period a short 8 seconds, at The Groyne. The wind is dead glassy, which is a massive positive, giving you clean conditions, but the energy is weak (165). The water’s sitting at 68°, which is about 2° cooler than normal for this time of year – not a huge deal, just a touch fresh.
That Thursday afternoon window is your only real go for the first week, because after that it turns into a write-off. Friday the 24th, through the weekend, and into the next week, it’s all poor surf conditions. The swell stays small and weak, the wind swings around onshore or cross-shore, and it gets choppy and messy. You’re looking at a solid 9-day gap with nothing worth paddling out for.
The second week finally shows some life, but the wind ruins it. On Thursday the 30th of July, the swell bumps up to 5ft from the SE, but the wind is a strong 16 mph cross-onshore, making it choppy and messy. The energy picks up (244), but the quality is gone.
There’s a window around the 1st of August that looks promising on paper – Saturday morning and afternoon have a clean offshore cross-off wind from the SSW at 16-19 mph. Swell is 4ft to 4ft from the SE with a period of 9 seconds. The energy is solid (238-255). But wait – the file calls it “poor surf conditions”. The wind is clean, but the swell direction (SE) is cross-onshore to the east-facing reef, and the period is short. It’s a tease – looks good on the beach, but the wave quality just won’t be there due to the setup.
The best stuff, if you can handle it, comes around the 5th and 6th of August. Wednesday the 5th has 8ft SE swell with a long 11-second period. The energy is huge, with values of 1350 and 1380 – that’s serious juice. But the wind is fresh cross-onshore from the ESE, making it lumpy and messy. That’s only for experts, and even then, it’s not clean. Thursday the 6th afternoon peaks at a massive 10ft SE swell with a 13-second period, and an enormous energy reading of 4284. But the wind is directly onshore from the ESE at 12 mph. That’s going to be a washing machine, and far too big and messy for anyone but the most experienced paddle surfers. It might actually be more interesting for a kite surfer.
Friday the 7th of August brings 6ft SE swell, still with a long 13-second period, and the wind lightens to 9 mph from the east, still onshore. The energy is still very high (1152-1224), and the file calls it “marginal surf forecast”. The long period groundswell will be breaking straight at this beach-reef setup, so it won’t be easy to ride.
Honestly, the only standout window for clean, fun surf is that tiny Thursday afternoon on the 23rd of July. After that, it’s 9 days of nothing, then a lot of big, windy, and messy swell. If you’re desperate and expert-level, the 5th to 7th of August has size, but don’t expect any beauty.
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.
