Table - best surf conditions forecast for The groyne over the next 16 days.
Alright folks, Rusty here. Let’s break down the surf ahead.
The first few days are rough. Wednesday and Thursday mornings see some SE swell pushing 7ft down to 5ft, with a period of 12 to 11 seconds, packing moderate to strong energy (2023 and 638). But the wind’s blowing hard out of the SSE at 15 to 19 mph, putting a nasty cross-chop on it. It’s messy, lumpy, and conditions are poor. Kites might have fun, but paddling in is a chore.
Friday stays average – moderate cross-shore winds and rain showers, swell around 5ft to 6ft, but the quality’s not there.
Saturday 11th July morning is the first real standout. Swell drops to 3ft from the SE, period of 10 seconds, but the wind goes light – SSW at 3 mph, cross-off, clean. That’s glassy. The energy is light (257), so it’s small, but it’ll be fun on the reef. Water temp is about average. Crowds are possible, but on that size, no big deal.
Sunday 12th July morning is the real gem. Offshore WSW wind at 12 mph, clean, with 3ft of ESE swell, 11-second period. The model says “expect good surf conditions,” and the energy is moderate (200). That’s the session to aim for. Afternoon stays clean with lighter offshore wind, though the swell eases.
Then the second week goes quiet. Monday through most of the next week, swell drops to 2ft and under, energy in the low two-digits (26 to 57). There’s a bump around 17th and 18th July with swell up to 4ft to 5ft, but the period is short (6-8 seconds) and the S wind is up at 19 mph – lumpy cross-chop. Not worth it.
We get a brief pulse on 21st July (Tuesday morning) – 5ft from ESE, 7-second period, clean with light cross-off wind, moderate energy (223). Rideable, but the short period means weaker waves. On the reef, that’s a caveat.
Overall, there are long gaps of several days with nothing good. The end of the run from around the 14th onward is mostly poor or marginal.
Best bet: Saturday 11th July morning (clean, 3ft SE) and Sunday 12th July morning (clean offshore, 3ft ESE) at The groyne. That’s your window.
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.
