The Lowdown

Alright folks, Rusty here. Let’s break down what’s coming for the next couple of weeks.

First thing, it’s a bit of a slow start. The Groyne, a reef break, is the only spot on the menu, and the first few days are pretty underwhelming. Tuesday morning, August 4th, we’ve got a glassy 2 ft SE swell, but the energy is weak – only 103. The water is sitting at 68°, which is about 2° cooler than average for this time of year, so nothing unusual. The waves are small and the conditions are just "so-so." It’s not a total loss, but it’s not calling you out of bed.

Wednesday morning, the 5th, picks up a little to 3 ft from the east, with a 10-second period and a bit more punch (170 energy). Glassy again, which is a gift. That’s the best of the early week – clean, small, but surfable. Thursday morning, the 6th, drops back to 2 ft with a weak 8-second period, so it’s a grind.

From Friday through the weekend, the swell holds around 2 to 3 ft, but the wind gets messy – cross-shore and cross-onshore, so it’s choppy and ugly. The energy is weak to moderate, but the quality is poor. Sunday morning, the 9th, we see a jump to 4 ft from the east with a 9-second period and 313 energy, but the wind is cross and the report says "marginal." It’s frustrating.

The following week, Monday the 10th through Wednesday the 12th, the mornings clean up with a light offshore or cross-off breeze, and the swell stays around 3 ft from the east. Periods are 9 seconds, and energy is in the 150-190 range. These are your best windows for a real surf – small but clean, and the reef will handle it fine. Wednesday afternoon, the 12th, actually has a gentle offshore wind, which is a rare treat.

Then things get interesting. From Thursday the 13th onward, the swell builds. By Friday the 14th, we’re looking at 5 to 5 ft SE swell with periods of 10-11 seconds and energy jumping to 473-492. That’s a lot of power, but the wind is cross or onshore, so it’s messy. The reef can handle the size, but the chop will make it a fight.

The real standout window is Tuesday the 18th and Wednesday the 19th of August. Tuesday morning, we’ve got a 6 ft SE swell with a 10-second period and a massive 626 energy. That’s proper groundswell. The wind is light cross-shore, so it’s not perfect, but it’s the best looking swell of the whole run. Wednesday morning, the 19th, is even more powerful – 6 ft SE with a 9-second period and a whopping 857 energy. The wind is just a whisper, light cross-shore. That’s the one to mark on the calendar. It’s too big for beginners, but for the experienced crew, that’s a solid session. The reef at The Groyne will turn that energy into some proper waves.

Bottom line: the early days are small and average, the middle of the run is clean but small, and the last few days are where the power shows up. If you can wait, the 18th and 19th are the real deal.

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.
