The Lowdown
Alright, Rusty here again for the imperial version. Let's talk Bennion Beach Cleggies for the next two weeks. This is a reef break that doesn't fire all that often, so we gotta be smart about it. The water is 62°, which is a good 4° colder than usual, so don't even think about a spring suit.
We kick things off on Sunday the 16th with a solid pulse. Swell is 6ft to 7ft from the WSW with a long 15 to 16 second period. The combined energy is strong (1766 to 2060). The wind is a cross-offshore breeze from the NNE at 16 mph, keeping the surface clean. It’s an inconsistent break and crowds are a real possibility, but the first few sessions of the window are your best bet. This is the highlight of the early days.
Monday the 17th is a total loss. The wind goes onshore and strong, ruining a solid 7ft to 12ft swell. Tuesday the 18th has the same huge 12ft swell with lighter wind, but that is just too much water moving for this reef. Only for the real experts, and even then, it’s sketchy. The energy is enormous (5848 to 6118).
The rest of that first week into the second is a real mixed bag of either big, messy waves or small, junky ones. There are a few clean moments, like Wednesday the 19th and Friday the 21st, but the swell is either too big or the tide is wrong. The consistency just isn't there.
Look to Sunday the 23rd for the next real highlight. The swell drops to a cleaner 6ft to 6ft from the WSW/SW, but the wind goes offshore from the East at 6 to 9 mph. It’ll be glassy with a decent 14 to 15 second period. The energy is moderate (1368 to 1303). This is the best day of the second week.
Then we hit a real dry patch from the 24th through the 30th. The swell is either too small or too big, and the wind is mostly onshore, making a mess of things. There’s a tease on the 26th with a 10ft swell and light wind, but that's just too big for this spot.
The very last day, Monday the 31st of August, is a sleeper. The swell is a small 5ft from the WSW at 15 seconds, but the wind is light and offshore from the ESE. It’ll be clean. It’s a small wave day, but it’s the only other truly clean window in the whole second week.
Rusty, signing off.
