The Lowdown
Alright, Rusty here again. Lookin’ at the same stretch but in feet and mph for those who think that way.
First things first – the early days are a write-off. We’re stuck with a cross-off ENE breeze blowing 12 to 16 mph and swell that’s barely a foot and a half. Combined energy numbers are low – staying below 300. The water’s 80°, which is normal for the season, but the surf itself is useless for paddle surfing. You’d be better off doing something else.
There’s a slow build starting Monday, 10th August. Swell creeps up to about 2ft from the SSW, combined energy hitting 530. Still only marginal, but you can see the pulse starting. The wind stays cross-off.
The best window opens Wednesday 12th August into Thursday 13th August. Wednesday afternoon sees waves around 4ft from the S with an 18-second period – that’s proper groundswell. Combined energy hits near 1000. Wind is still cross-off, but the surf looks clean. Thursday morning is the pick: 4ft from the S, 16-second period, combined energy at 909. That’s a nice, solid south swell hitting a reef that loves that direction. Crowds are possible but not guaranteed. The swell is big enough that beginners might find it a handful, but for anyone with a bit of time in the water, it’s the best looking day of the whole 16-day run.
Saturday 15th August morning throws a curveball – 6ft from the E but period crashes to just 7 seconds. That’s wind swell junk, all bump and no shape. Combined energy is 810 but it won’t surf well. By afternoon it’s back to 3ft from the S.
From Sunday 16th August onward, it’s back to small surf (2ft or less) with cross-off winds at 15-19 mph and poor conditions. Nothing to get excited about.
So bottom line – circle Thursday, 13th August if you can. Brenneckes with 4ft of south swell and a long 16-second period is as good as it gets this stretch. The wind’s not perfect but it’s clean enough. That’s your day.
Rusty.

Information about the Brenneckes Surf forecast
The above surf forecast table for Brenneckes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Brenneckes can be found by selecting the local surf guide option on the grey menu. Our Brenneckes 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 (Brenneckes) 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 Brenneckes 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.
