The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for Broadhaven South. Honestly, it’s pretty grim reading for the next week or so.
We’ve got a real flat spell on our hands. The swell energy is weak, barely ticking over most days with values like 117 (moderate) early on, but then dropping right off into the low double digits – 21, 12, that kind of thing. The water temperature’s sitting at 65°, which is a touch warmer than normal for this time of year, but you won’t be feeling it much if you’re not getting wet.
The only real glimmer of hope, and I mean a tiny one, comes on Thursday morning, the 13th of August. We’ve got a clean 3ft swell from the WSW with a light NW offshore, and the energy bumps up to 222 (moderate). That’s the best window in the whole run. It’s surfable, but just very ordinary. The rest of the first week is a write-off with poor surf conditions and cross-onshore or stiff cross-offshore winds.
Then we hit a massive gap. From the 14th right through to the 23rd of August, every single session is rated as poor surf conditions. The swell energy is a joke, often well under 100. The wind is messy, the period is short and choppy. There’s a brief moment on the 24th of August, a Monday morning, with a 5ft swell from the WSW but the energy is still only moderate at 236, and it’s described as surfable but very ordinary. That’s a long way out and not worth getting excited about.
The second week is more of the same – tiny, weak, and uninspiring. The 27th of August sees a 1ft and 2ft swell with energy in the 30s and 40s. A total non-event.
So, the standout here is that Thursday morning, the 13th of August. If you’re desperate, you might get a few knee-high waves with a clean offshore wind, but it’s not going to be a day to remember. For the rest of the forecast, honestly, you’d be better off checking the kite forecast because the wind will be stronger than the waves.
Rusty.
