The Lowdown
Alright, Rusty here. Let’s break down what’s coming. We’ve got a solid run of swell, but not every session is a keeper. The real highlight is a couple of super clean windows early on, but then things get heavy and too big for the usual spot.
First wave of action is on the afternoon of the 12th at Bennion Beach Cleggies. We’re looking at a solid 7ft SW swell with a strong, long period of 14s, packing some serious energy (1807). The water is a bit cooler than average for this time of year, so you might want a thicker wetsuit. The wind is cross, so it’s not perfect, and the surf is a bit marginal. It’s a start, but not the best of the run.
The standout is definitely Thursday morning, the 13th. That’s your session. The swell is still a chunky 7ft from the SW, but the period jumps to a very long 16s, and the energy is pumping (2299). More importantly, the wind is offshore from the ENE at just 3 mph. That’s glassy, clean conditions. The report says it’s excellent for experienced surfers, and that’s spot on. This is the one to circle. The spot is a reef, and it’s inconsistent, so you’ll need to be patient, but when those sets come through, they’ll be beautiful. Crowds are often here, so expect company.
Friday morning, the 14th, is another good shout. Same 7ft SW swell, 16s period, with a cross-offshore wind from the ENE at 6 mph. That’s clean, with a touch more wind than Thursday but still really good. The afternoon of the 14th is a real treat, too, with a glassy 7ft SW swell and 16s period. The wind goes to a complete glass-off from the SSE. That’s about as clean as it gets.
Saturday the 15th drops off a bit. The swell backs down to 6ft from the WSW, and the period drops to 14s. The morning has a cross-offshore wind that keeps it clean, but it’s a step down in power.
From Sunday the 16th onward, the swell starts jumping around. Sunday morning has a 7ft WSW swell with a 16s period, but the wind is a stiff 16 mph cross-offshore. It’s clean but getting blown out. The afternoon is similar with a bigger 8ft swell.
Then we hit a rough patch. Monday the 17th goes to crap with strong onshore winds and lumpy conditions. By Tuesday the 18th, the swell is way too big. We’re looking at 13ft on Tuesday morning and 12ft in the afternoon. The energy is massive (7202 and 7627). This is experts-only territory, and even then, the reef is predicted to be too big to handle. It’s a no-go for paddle surfing.
Wednesday the 19th is a write-off, with strong winds and messy surf. The swell is 8ft but with a short period of 8s, making it junk.
Thursday the 20th is a monster. A 15ft W swell with an 18s period and an insane 21408 energy reading. Again, too big for this break.
The rest of the fortnight is a mixed bag of big, blown-out swell and periods of smaller, cleaner but marginal surf. There’s a window on the morning of the 22nd with a 10ft SW swell and a glassy cross-offshore wind, but that’s still a big wave for this reef. The 23rd sees the swell drop back to 8ft with a clean cross-offshore wind, which is a better size, but by then the forecast is less certain.
After that, it tails off into smaller, onshore slop. For the most part, after the first week, the swell is either too big or the wind is on it. Stick to Thursday morning the 13th for the cleanest, best-shaped waves.
Rusty.
