The Lowdown
Right then, let's talk about what's on offer at Broadhaven South.
Truth be told, it’s a bit of a heartbreaker looking at the next couple of weeks. The overall pattern is one of wind-ruined potential and a whole lot of waiting. For a spot that’s inconsistent at the best of times, this is a tough run. There’s a real gap of flat, rubbish conditions right through the middle of the period, from around Thursday the 10th right through to the following week.
The only real window that gets my blood pumping is right at the very end. So you’ve got to patient.
Monday the 7th kicks off with a 7 ft swell from the WSW, but it’s carrying a 15-18 mph wind, so it’s only giving marginal, borderline surf. Not worth suiting up for.
That carries into Tuesday the 8th – there’s a 6 ft WSW swell with a helpful NW offshore, but the whole "marginal surf forecast" tag tells me the conditions aren’t coming together. It's frustrating.
A window shows its face Wednesday morning the 9th. A lighter 5 ft of west swell, the wind is offshore from the NW, and it’s clean. The water’s about average for this time of year. Honestly, it’s the best you’ll do for the first week, but it’s still "surfable waves but very ordinary conditions." It’s a grovel unless you’re desperate.
Then the wheels really come off. From Thursday the 10th through the weekend and into the next week, it’s gap after gap of small, cross-shore wind, lumpy chop, and flat spells. The combined energy drops right off – (24 on Thursday, down to 9 on Friday afternoon). You’re looking at a solid 8-day blank run here.
Tuesday the 15th morning offers a tiny glimmer: 5 ft of west swell with glassy conditions. That’s a rare treat for the consistency in the lineup – it’s clean, light, sometimes, you might get it to yourself. Still only "surfable waves but very ordinary conditions" though.
But the real standout, the one you circle on the calendar, is Thursday the 17th. Yes, it’s a week and a half away, and yes it’s light rain, but look at this: an 12 ft West swell rolling in with a 10-second period, and the wind is cross-off from the WSW. The combined energy is a meaty 2652. This is proper, heavy groundswell. For Broadhaven South, that’s going to be a real beast. That 12 ft is absolutely for experts only – if you're a learner, stay on the beach. It’s going to dump. The long period means it could run a bit straight here at a beach break, but with that much juice, it’ll be a powerful, hollow bank if it finds the right one.
That Thursday stands as the only true standout. After that, it drops off again into a mix of moderate swells and messy cross-shore winds right through to the end of the outlook.
So in short: suffer through a long, flat, wind-blown wait, keep your eyes on the 15th for a glassy session, and if you've got the stones, be ready for Thursday the 17th. That’s the one.
