Alright, Rusty here again, switching to feet and inches for you.
We’re looking at The Groyne, and the first week is a slow one. You’ve got about a week of tiny, ordinary waves before anything with real push shows up. The water is a bit colder than average for this time of year, sitting around 69°, so expect a slight winter chill.
The session to circle on your calendar is Tuesday, July 21st. The morning is the pick: a clean 4ft swell from the ESE, with a 10-second period and light offshore wind from the south. The energy is solid at 605 (moderate wave energy). It’s clean, glassy, and should offer some fun, rippable waves. This is the best of the whole run.
Before that, from the 16th to the 20th, it gets messy. Swell pushes up over 8ft on the 18th, with a long-period groundswell hitting 12 seconds, but the wind is screaming from the south at 25 mph, creating lumpy, cross-chop. That’s more of a kite-surfing day than a clean paddle session. The energy is massive (1750 on the afternoon), but the quality is poor.
The 24th of July (Friday morning) is another decent option: 4ft from the east with a 12-second period (long-period groundswell) and clean cross-offshore wind from the NNW. The energy is moderate at 387, and it’ll be well-shaped for the reef. It’s a good backup, but not as good as the 21st.
After that, it fades back into small, ordinary conditions through the 27th. Nothing else stands out.
Bottom line: wait for the morning of Tuesday, July 21st. That’s your cleanest, best chance. Friday the 24th is a solid second pick. The rest is either too small, too windy, or too messy to bother.
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.
