The Lowdown

Alright folks, Rusty here. Let’s get into it.

We’re looking at a pretty tough stretch ahead for Brenneckes. This reef break is exposed to the south, and the swell we’ve got on the way just isn’t playing nice. The first few days, from Thursday the 13th through the weekend, there’s some solid energy in the water – we’re talking a long-period, 16-second groundswell from the south on Thursday, with the combined energy reading 1050 (moderate to strong). But here’s the kicker: the wind is a stiff cross-offshore from the ENE at 15 to 22 mph. That’s raw, bumpy, and fighty. The wave heights are around 4 ft on Thursday, but the conditions are “marginal” and the whole setup feels like a chore. It’s not the kind of day you tell your mates about.

The best bet in this whole outlook, and it hurts to say it, is the Saturday the 15th. The swell jumps to 8 ft from the east, with a short period of 8 to 9 seconds. The combined energy is strong (1194 to 1276). That’s a lot of water moving, but it’s a windswell – fat, lumpy, and tricky. The wind is still a fresh cross-offshore from the NE at 19 to 22 mph. For a beginner, 8 ft is too big, and honestly, for most paddle surfers, this is a tough, drifty, bumpy mess. This setup looks more interesting for kite surfing than paddle surfing. The break is a reef, so that short-period east swell is going to be sectiony and hard to love. The water temp is about average for this time of year, so no shock there.

After Sunday the 16th, the swell just drops off a cliff. From Monday the 17th right through the rest of the 16-day window, we’re looking at tiny, weak waves – mostly 2 ft to 3 ft, with very long periods (14 to 18 seconds) from the south or southwest. The combined energy is in the low to mid hundreds, which is weak. The wind stays cross-offshore from the ENE or E, but it’s not enough to save the day. The surf is consistently poor or marginal. There’s a little blip on Saturday the 22nd where the morning shows 2 ft from the SSW at 16 seconds and a “good surf” label, but honestly, that’s still a knee-high dribbler with no push. Don’t get your hopes up.

Verdict: There’s no standout session here. The only window with any size is the weekend of the 15th, but it’s windy, messy, and too big for beginners. The rest of the forecast is a flat, drawn-out pause. For a spot that’s fairly consistent, this is a rare blank run. We’ll just have to wait for the forecasts to change.

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.
