The Lowdown
Hey, Rusty here. Gotta be honest — the next few days are a bit of a write-off. The groyne is copping messy cross-onshore wind and weak, short-period swell from Friday 31 July right through the weekend. Winds are blowing from the SSE and SE at 15 mph with a cross-chop, and waves are only 3 ft to 5 ft. Not worth the effort. You’re looking at a quiet run until Monday morning 3 August.
Monday morning (3 August) is the best of the lot. Wind shifts to SSW at 9 mph, cross-offshore, and the swell drops to 2 ft, but the period stretches to 13 seconds — that’s a proper little groundswell — and combined energy hits 397 (moderate). Clean conditions, small but quality lines on the reef. Crowds can show up sometimes, so get in early.
Monday afternoon goes sloppy with light cross-onshore breeze. Tuesday (4 August) morning goes glassy — dead calm — with a tiny 2 ft ENE swell at 6 seconds and weak energy (107). Surfable, but just okay.
Then we stall through the middle of the week with very small swell (2 ft to 3 ft) and only occasional clean windows. Wednesday morning (5 August) and Thursday morning (6 August) are clean, cross-offshore, but the swell energy is too low (86 to 124) to get stoked about.
Tuesday 11 August morning looks clean again, with a 4 ft SSE swell at 6 seconds, energy still low (135). Wednesday 12 August is your other real standout: morning shows a 4 ft E swell at 11 seconds, strong energy at 418, with WSW cross-offshore winds at 9 mph — clean and solid for the size. Afternoon keeps the offshore wind (WSW 12 mph) with a 3 ft E swell, 11-second period, energy at 390 — another good window.
Thursday (13 August) goes smaller but clean. Friday 14 August morning has offshore WSW wind at 9 mph, 3 ft E swell with 11 seconds, combined energy 226 — clean, small, well-shaped for a quiet paddle.
After that, it fades to small, clean but low-energy surf through Saturday 15 August.
Water temp is 68°F, about 2° cooler than average for this time of year — a bit chilly, so grab the wetsuit.
Best bets: Monday morning 3 August and Wednesday 12 August. The rest is either too small, too messy, or flat. Longer-range stuff is promising but less certain.
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.
