The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for the next couple of weeks.

We’ve got a bit of a slow start, but things do pick up. The first real action worth getting in the water for is this Wednesday afternoon. Brenneckes is a reef setup that’s fairly consistent and works best on a south swell. Water temp is sitting right on 81°, which is pretty much spot on for this time of year – no surprises there.

So, for Wednesday afternoon, the 9th of September, we’ve got some clouds overhead and the wind is glassy from the SSE at just 3 mph. That’s clean. Swell is a modest 3 ft from the SSW with a lovely long period of 13 seconds. That’s groundswell, and on a reef, that’s going to shape up nicely. The combined energy is moderate (236). It’s a beginner-friendly spot, but the quality is there for anyone to have a fun session.

Thursday the 10th through the weekend, we’re looking at smaller surf, mostly 1 ft to 2 ft, and a persistent cross-off wind from the ENE at 9 to 12 mph. It’s clean but small and ordinary. Not worth rushing out for. The energy drops right off, with readings in the double digits by Sunday.

Now, here’s the standout. Mark your calendars for Tuesday the 15th of September. Morning and afternoon both look solid. We’ve got 2 ft of SSW swell rolling in with a period of 20 seconds – that’s a very long period groundswell, and on a reef like Brenneckes, that’s going to produce some proper, lined-up waves. The wind is cross-off from the east, light at 6 to 9 mph. Combined energy is strong, hitting 415 in the morning and 398 in the afternoon. This is the best on offer, no question. It’s a beginner spot, but with that period and size, it’ll have plenty of push for a good session. Crowds can be a factor sometimes, so get in early.

After that, from Wednesday the 16th right through to the 20th of September, we’re in a bit of a holding pattern. Swell hangs around 2 ft to 4 ft from the SSW, but the wind stays a moderate cross-off from the ENE at 12 to 16 mph. The energy builds into the 900s by Friday the 18th, so there’s plenty of juice, but the conditions are only marginal – the wind keeps things bumpy. Not a total write-off, but not the pick of the fortnight.

Then, a shift. On Monday the 21st of September, the swell direction swings around to the east, and the period drops to a short 8 seconds. We’re looking at 6 ft to 5 ft of short-period swell. That’s a bit of a different beast. It’s cross-off from the east, light to moderate. The energy is still strong (525). This setup might actually be more interesting for kite surfing than paddle surfing, as that short-period stuff can be a bit crumbly and messy for a reef break.

That east swell continues through Tuesday the 22nd, dropping from 4 ft to 4 ft, still short period. Winds stay light and cross-off. It’s surfable, and the scores say it’s good, but the short period is a caveat for a reef break.

By Wednesday the 23rd and Thursday the 24th, we’re back to SSW swells around 2 ft to 3 ft, but the wind turns onshore from the south and SSW. The conditions get sloppy. Not your best days.

So, to wrap it up: the real standout is Tuesday the 15th of September. Wednesday the 9th is a fun warm-up. The rest is a mixed bag of small, windy, or short-period stuff. Keep an eye on that Tuesday.

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.
