The Lowdown

Alright, let’s talk about this in feet and degrees. The Groyne is in for a proper rough patch for most of the next couple of weeks, but there are a couple of windows that might just save the trip.

Starting off, nothing. Wednesday the 9th is a bust – tiny 3 ft swell from the SE, period of 5 seconds, and cross wind. No good. Thursday the 10th brings some real size, with 7 ft to 8 ft of SE swell, but the wind is a fresh 35 km/h from the SSE, hitting it onshore. It’s lumpy, messy, and unsafe. The wave energy is moderate (314) in the morning, rising to strong (780) in the afternoon, but it’s all blown out. That same pattern – sizeable but ugly – sticks with us right through to Monday the 14th. The swell stays between 4 ft and 7 ft, but the wind is always cross-onshore, and the period is short. That’s a solid week of poor surf.

The one real diamond in the rough is Thursday morning the 17th. The swell drops to a clean 3 ft from the ENE, but the wind goes glassy – just 5 km/h from the NE. The water temp is about average for this time of year. The energy is weak (98), but on a reef, a glassy morning with a little 3 ft groundswell is going to feel like a dream. Clean, tidy, and small. Crowds are possible.

After that, it’s back to the grind. Friday the 18th and Saturday the 19th are small and messy. We get another glassy morning on Saturday the 19th, but the swell is a tiny 2 ft from the E. Not worth it. The next week stays quiet, with small, short-period swell and cross-on winds. On Monday the 21st we see a brief spike in the afternoon with 6 ft SE swell and moderate energy (314), but the wind is a moderate 20 km/h cross-onshore. Just messy.

The only other possible session is Wednesday morning the 23rd. Again, glassy conditions with a 5 km/h ENE wind, and a 3 ft NE swell with a 8-second period. The energy is moderate (155). It’s surfable and clean, but nothing special.

So, the standout is clearly Thursday morning the 17th – glassy, clean, and fun on the reef. If you miss that, your next best bet is Wednesday morning the 23rd. For the rest, it’s a long wait.

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.
