The Lowdown
Right then, let’s have a look at what’s on the cards for our corner of the coast. I’m lookin’ at Broadhaven South here, and I gotta be straight with you—it’s a bit of a mixed bag over the next couple of weeks. This spot is a sheltered little number, and it’s inconsistent, so it’s never gonna be pumping every day. We’ve got a long stretch of poor conditions to sit through before things start to get interesting.
The first few days are a write-off, honestly. There’s a touch of swell on Friday the 4th and Saturday the 5th, but the wind is a mess—cross-off or cross, and the quality just isn’t there. The water temp’s about average for this time of year, so nothin’ to write home about there. You’ll be looking at some choppy, poor surf with combined energy around 180 to 690 (moderate). Not worth a paddle.
Sunday the 6th is even worse—tiny, onshore, just a mess.
Right, here’s where it gets a bit more interesting. Monday the 7th, we’ve got a proper pulse of swell rollin’ in. The morning shows 8 ft from the WSW with a long period of 13 seconds—that’s proper groundswell, lads. The combined energy is a meaty 1750 (strong), so there’s some grunt in the water. It’s a cross-off wind, so the face will be clean. But the guidance says it’s marginal, and with a period that long, it might be a bit too straight for a beach break like this. Still, for the experienced surfer who knows the bank, it could be the best of the lot. The afternoon stays solid with 7 ft and 12-second periods, energy at 1183 (strong).
Tuesday the 8th is a no-go—8 ft from the W but with a short 8-second period and a screaming 22 mph wind. That’s just a washing machine, and for experts only due to the size. The combined energy is 866 (moderate), but the wind ruins it.
Then we got a quiet spell Wednesday the 9th and Thursday the 10th. Thursday morning actually looks decent—7 ft from the WSW, 8-second period, and a nice offshore wind from the WNW. The combined energy is 597 (moderate), and the conditions are described as “expect good surf conditions.” That’s a window to get out there, but it’s inconsistent, so you gotta pick your moment.
After that, it dies right down. Friday the 11th through Sunday the 13th is tiny, weak, and not worth a second look. The combined energy drops to below 200 (weak). A real flat spell.
Now, here’s the standout for the second week. Monday the 14th. Look at this: 8 ft from the WSW with a 7-second period, clean conditions with a cross-off wind, and combined energy of 635 (moderate). It’s a morning session, and it says “expect good surf conditions.” That’s a solid call. The size is right on the edge for beginners though—over 5 ft, so it might be a bit much for the groms. For the intermediates and up, that’s the one to aim for.
The rest of the week after that is a slow fade. Tiny waves, weak energy, and nothin’ to get excited about. The 18th and 19th of September see some glassy conditions, but the swell is barely 2 ft.
So, to wrap it up: the best on offer is Monday the 7th for the big groundswell if you’re an expert and can handle the long period, or Monday the 14th for a more manageable, clean 8 ft with a better wind. The 7th is the real standout for power, but the 14th is the safer bet for a good session. It’s a quiet spot, and it tends to stay poor for a while, but the forecasts can change. Keep an eye on the charts.
