Alright, Rusty here. Let’s break down The Groyne for the next couple of weeks.
First few days are a no-go. Sunday the 5th and Monday the 6th are all cross winds and sloppy – don’t bother. Tuesday the 7th is the same story. Wednesday morning the 8th sees some real power with combined energy at 1914 (strong to very strong), but the wind is still cross, so it’s messy. The first proper window hits Saturday morning the 11th: glassy conditions, clean 0.9m swell from the ESE. Water temp is about normal for this time of year. The Groyne is a reef spot, wide open to the SE, and that 11-second period means real groundswell. It’s not big, but it’s clean – and that wind is dead calm. Crowds are possible so get in early. After that, Sunday the 12th has offshore wind but tiny 0.6m swell – ordinary but rideable. Monday the 13th is similar and weak. The rest of the second week is small and short-period. Thursday the 16th and Friday the 17th stay average. Saturday the 18th offers a small bump of 0.8m ENE with light cross-off wind, but nothing special. The standout is that Saturday morning the 11th – glassy, clean, and long period. That’s your session.

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.
