The Lowdown
Alright, listen up, crew. Rusty here. We've got a real mixed bag on the cards for the next couple of weeks. The only solid option on the table is Bennion Beach Cleggies, a reef setup that's a bit inconsistent, so you gotta pick your moments. The water's sitting at 63°, which is a bit colder than normal for this time of year, so you might want a spring suit.
Now, let's talk about the first standout. Thursday morning, the 20th of August, is looking like the absolute pick of the bunch. We've got a big, powerful 10 ft groundswell pumping in from the WSW with a very long period of 16 seconds, and the combined energy is massive at 4242. The real kicker is the wind: a gentle 3 mph easterly making it glassy. It's clean as a whistle. But listen, this swell is serious – it's too big for beginners, and you'll want to be an experienced surfer to handle it. The very long period also means it's going to be a bit tricky at a beach break, but at a reef like this, it could be absolutely firing. Crowds are possible here.
Friday morning, the 21st, is the next best bet. Still a solid 8 ft swell from the WSW, 15-second period, and the energy is strong at 2535. We've got a light 6 mph offshore easterly wind, so the surf will be clean. Again, experienced surfers only.
Saturday morning, the 22nd, is another one to pencil in. The swell drops slightly to 7 ft, but the period jumps to 17 seconds from the WSW, with energy at 2731. The wind is a glassy 3 mph from the NE, so it'll be clean. Still a big, powerful swell.
Sunday the 23rd is a write-off with messy cross-shore winds, and the swell drops, so don't bother.
Monday morning, the 24th, is worth a look. The swell is 7 ft from the WSW, a 14-second period, and the energy is 1848. The wind is a light 3 mph NE, creating clean cross-off conditions. Another one for the experienced crew.
There's a big gap of poor conditions from the 25th through to the 28th, with strong onshore winds and a lot of rain. Stay out of the water.
Then, on Friday morning, the 28th of August, we get a surprise return to form. The swell is still a solid 7 ft from the WSW, 13-second period, and the energy is 1551. The wind is a glassy, 3 mph SSE. It's clean and should be a good session for experienced surfers. This one is a bit more of a long-range call, so keep your fingers crossed.
After that, it's mostly a write-off again with a lot of strong, messy onshore winds and rain, or just too big and wild. The first week of September looks like a right-off as well, with huge, onshore swell. So, to sum it up: your best windows are the mornings of the 20th, 21st, 22nd, and 24th of August, with the 28th as a promising long-shot. Don't sleep on the 20th – that's the one.
Rusty.
