The Lowdown
Alright, let’s get into it.
Right now, we’re looking at a pretty bleak stretch here. Honestly, for the next week and a bit, there’s nothing worth paddling out for. From Tuesday the 18th of August all the way through to Sunday the 30th, every single session at Broadhaven South is rated as poor surf conditions. That’s a solid twelve or thirteen days of flat to messy, weak, and unsurfable waves. The combined swell energy barely cracks three digits on a couple of days (like Thursday the 20th with 265), but the period is short and the conditions just aren't coming together. Wind is often cross-off or strong, and when there’s a little pulse of swell, it’s got no quality behind it.
The one tiny glimmer comes right at the end of the run. On Monday morning, the 31st of August, we get a 4ft swell from the WSW with a 7-second period, and 157 units of combined energy. It’s still only “surfable waves but very ordinary conditions” – not a standout. The wind is cross-off from the WNW at 30 km/h (19 mph), so it’ll be clean enough for a grovel, but don’t expect anything exciting.
Then, on Tuesday the 1st of September, things finally wake up. A solid 10ft swell from the WSW, 8-second period, and a massive 1068 combined energy reading. That’s strong, powerful stuff. The wind is offshore from the NNW, 40 km/h (25 mph) – strong offshore and clean, but that’s going to be a real battle to get out. This is expert-only territory. The wave period is short, so it’ll be a bit lumpy and dumpy, but for the experienced crew, there could be some heavy, hollow wedges. The morning looks the biggest, with the afternoon dropping to 8ft. This is the only true standout in the whole forecast, but it’s for big-wave chargers only.
Wednesday the 2nd drops back down to 6ft and 6ft, but the wind swings onshore and cross, making it messy again.
As for the water temp, it’s 64°F with a 3°F anomaly, so a touch warmer than normal for this time of year – not a major issue, but noticeable if you’re used to the usual chill.
Crowds at Broadhaven South can be often, so on that Tuesday if the swell delivers, expect a crew. But given the size and wind, most will be watching from the cliff.
So, bottom line: sit tight for nearly two weeks, then on Tuesday the 1st of September, if you’ve got the balls and the paddle fitness, Broadhaven South could offer a heavy, challenging session. Not for the faint-hearted.

Further information to help with frequently asked questions about our surf forecast for Broadhaven South 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.
