The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for The Groyne.
Honestly, for the first week and a half, it’s a tough watch. The wind is just not playing nice for most of it, and the swell is messy. It’s not until Thursday the 23rd that we finally get a window that looks worth paddling out for.
The big problem early on is a strong, persistent cross-onshore wind from the southeast. Through Friday 17th, Saturday 18th, and into Sunday 19th, we’ve got a solid 6ft to 8ft of SE to ESE swell running, but it’s all short-period, lumpy, and choppy. The combined energy is moderate to strong – hitting 316 on Friday morning, peaking at 1392 on Sunday morning – but it’s just not clean. The wind is ruining it. Sunday afternoon gets a bit hectic with a strong breeze and messy cross-chop.
Monday 20th sees the biggest swell of the whole run, with 10ft ESE swell and a 10-second period, and combined energy readings over 1800. That’s a lot of power, but it’s still cross-onshore, lumpy, and only for the experts. Beginners would be insane to get out there. The following days, Tuesday 21st and Wednesday 22nd, the swell drops a bit but the wind is still cross-on, making it a poor choice.
Finally, a glimmer. On Thursday 23rd July, the morning is looking glassy with a light offshore wind from the SW, and the swell is a clean 4ft from the east, period 9 seconds. The combined energy is moderate (225). The water temp is about average for this time of year. This is the standout. It’s a small, clean, rideable morning. Get your shortboard out. The afternoon will see the wind come back onshore from the NE, so that window is tight.
After that, it’s messy again. The swell drops off through the end of July and into the first day of August, with a lot of small, weak, and cross-shore conditions. There’s a little pulse of 3ft, 12-second groundswell on Monday 27th, but it’s cross-shore and choppy. Not worth the drive.
The very last day, Saturday 1st August, shows a clean 3ft swell with a moderate offshore wind from the WSW. It’s small, but it’s the only clean option in the second week. The energy is very weak at 70, so it’s a longboard or a funboard kind of morning.
So, to sum it up: the Thursday 23rd morning is your best bet. It’s not huge, but it’s clean, glassy, and fun. After that, there’s a long gap of poor conditions until that small, clean window on August 1st. Keep your eyes open, but don’t hold your breath for the rest.
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.
