The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.

The overall picture is a bit of a slow burn. We’ve got a long stretch of marginal to poor conditions ahead, so don’t get too excited just yet. The first real glimmer of something decent doesn’t show up until the 6th of September, which is a solid gap of about a week and a half of mostly underwhelming surf.

The water here at Brenneckes is sitting at a warm 81°, which is about average for this time of year, so no drama there.

For the first week, from the 26th of August right through the 5th of September, it's a pretty flat and messy run. The wind is a steady cross-off from the ENE, which is actually a decent direction for this spot, keeping the surface clean. But the problem is the swell. We’re looking at small, weak, and short-period stuff most of the time, with heights scraping past 3 ft at best. The combined wave energy stays in the low to moderate range, most of the time under 600. The swell periods are all over the place, but a lot of it is short-period windswell, like that 7-second stuff from the east on the 29th and 30th of August. That’s just not going to have any power. The forecast calls it “poor surf conditions” for a reason. It’s a good time to clean the wax off your board.

Now, hold on to your leashes, because the tide starts to turn on the 6th of September (Sunday). That morning, we start to see some life. The swell picks up from the SSW at 3 ft, with a period of 16 seconds. That’s proper groundswell energy, folks. The combined energy hits 410, and the forecast says "expect good surf conditions." The wind is a gentle breeze from the east at 9 mph, keeping it cross-off and clean. That afternoon gets even better. The swell bumps up to 3 ft from the SSW, still a solid 17-second period, and the energy climbs to 578. The forecast is calling for "very good surf conditions." This is the standout. It’s not huge, but it’s clean, lined up, and has some real push. If you can only paddle out once in this whole outlook, make it the afternoon of the 6th of September at Brenneckes. The swell direction from the SSW is right on the money for this reef, and with that offshore breeze, it’s going to be glassy. Keep in mind this is a fairly consistent spot, but it’s also a beginner-friendly reef, so those 3 ft waves are perfect for everyone.

After that little blast of quality, the 7th of September still looks okay, but the energy drops off and the wind picks up again. By the 8th, it’s back to the poor stuff. The 10th of September has the weakest energy in the whole run, down at 192, so don’t bother.

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.
