The Lowdown
Alright crew, Rusty with the imperial take for Broadhaven South. We’ve got a 16-day outlook that’s slim pickings. There’s a real gap here. We get one good-looking session early on, and then a long dry spell of flat or poor conditions for days. Let’s get into it.
The one to point the van at is Thursday morning (13th August) at Broadhaven South. You’ll see a clean 3ft swell from the WSW, period a solid 10 seconds, and the wind is light out of the NW at only 3 mph—glassy smooth. The combined swell energy is moderate at 222, so there’s enough to hold your line. Water temp is a touch warmer than average at 65°F, so it’s comfortable. This is a sheltered, inconsistent little spot, and the SW swell direction suits it well. It can get busy when it shows life, so expect company on the peak. Not a big-wave day, good for intermediates, but the inconsistency means you’ll have some lulls.
After that, things fall apart. By Thursday afternoon (13th), the wind picks up and the quality drops. Through Friday (14th) to Sunday (16th), it’s tiny, weak surf under 3ft with messy wind. Combined energy readings drop below 110, mostly a dribble. Monday (17th) is nearly flat with just 0.3ft showing.
Tuesday morning (18th August) brings a 6ft pulse from the west, but it’s short-period windswell at 7 seconds. The energy is moderate at 269, but with a strong 16 mph cross-offshore wind, it’s going to be rough and only for experienced surfers. The rest of the second week is a write-off: onshore winds, rain, and weak swell dominate until the end of the month. Thursday afternoon (27th August) sees a 5ft SW swell with a 257 energy reading, but again the wind blows hard.
Like I said, if you want a wave, dawn on Thursday (13th) is the call. After that, you’re waiting.
Rusty.
