The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s coming our way at Whitesand Bay over the next couple of weeks. I’ll be honest, straight off the bat, it’s a tough watch for the first week and a half. The surf is there, but the conditions just won’t play ball. We’ve got a long stretch of poor quality on offer, so don’t be in a hurry.
Starting from the 25th of August right through to the morning of the 7th of September, it’s a real struggle. We’ve got wave energy bouncing between a weak 19 and a moderate 237, but the wind is all over the place – mostly cross-onshore or onshore, and at times fresh to strong, so the surface is going to be choppy and messy. The waves themselves are small for a lot of that time, under 2 ft, with short, weak periods. There is a pulse of swell on the 29th of August with a combined energy of 237 (moderate), and then again on the 30th with 649, but the wind is howling cross-onshore, making it properly ugly. It’d be more fun for the kite crew than paddlers.
The end of August and beginning of September gets a bit bigger. On the 31st of August we see a 10 ft swell with an onshore gale-force wind, so that’s one for absolute experts only, and even then it’s going to be blown to bits. Then into the 1st of September, near gale force winds ruin a 10 ft and 8 ft pulse. That’s a pass from me. The 5th of September offers a taste of relief with an offshore breeze from the East at 31 mph, but the near gale force makes paddling out a real mission. The water temp is about average for this time of year, nothing to write home about.
Now, after nearly two weeks of looking at junk, we finally get a window that’s worth setting the alarm for. The morning of the 8th of September is the standout in the whole 16-day run. We’ve got a 6 ft swell from the WSW, and importantly, a clean cross-offshore wind from the NNE at 16 mph. This is going to produce clean lines. The period is a very long 15 seconds, so this is proper groundswell. This kind of long-period swell can sometimes race through beach breaks, but at Whitesand Bay, if it’s lining up right, you’ll get some beautiful, lined-up walls. The combined swell energy is a strong 2094, so there is serious power behind it. The easterly wind should keep it glassy. It might be a touch big for beginners at 6 ft, but for anyone with a bit of experience, get on it. The afternoon of the 8th holds similar promise with a 7 ft swell from the WSW and a cross-offshore breeze. After that, the 9th of September morning settles right down to a more manageable 4 ft, with a light offshore from the ENE. A gentler, cleaner option for the longboard or a learner session.
To be frank, it’s a grim start, but that 8th of September is worth waiting for. It’s a long way out, so keep an eye on the charts, but that’s the one.
Rusty.
