Super Tubes Surf Forecast and Surf Report

Alright, let’s talk it through, Rusty style.

We’ve got a solid run of surf on the way, but the start is a bit tricky. The first few days are a tease, with Saturday really the first proper day to get excited about, but after that it builds into something special.

Friday starts with a 5 ft SW swell, period of 15 seconds, so plenty of push and that long-period groundswell energy. Wind is cross from the north though, which puts a bit of a chop on things. Water temp is a crazy 52°F, which is far colder than usual for this time of year (anomaly of -14°F), so you’ll want a thick steamer and booties. Not the best conditions, but there’s wave energy (930).

Saturday morning is where things clean up nicely. The swell drops a touch to 4 ft, still from the SW with a 14-second period, but we get glassy conditions with an ESE breeze at just 3 mph. This is clean, inviting surf at Super Tubes, and it’s just about perfect for getting your fix. The energy sits at 657, which is decent.

Sunday brings a noticeable step up. Swell builds to 5 ft to 5 ft, period drops slightly to 12 seconds, and the wind goes cross-offshore from the WNW and SW. This is clean, well-shaped surf and the energy climbs to 689 and 742. It’s starting to get proper.

Monday 17th August is the first real highlight. The swell jumps to 8 ft, period 14 seconds, and we get a gentle offshore wind from the WSW in the morning. That’s excellent for experienced surfers. The energy jumps into four digits at 2094 – moderate to strong. The afternoon stays clean with cross-offshore wind. This is a standout window.

Tuesday 18th morning is magic: glassy conditions, ENE breeze at just 3 mph, with a 7 ft SW swell and 13-second period. The energy is 1408. This is a top-tier morning, but the afternoon gets blown out by a strong cross-onshore wind (ESE at 16 mph), so get out early.

Wednesday 19th is another belter for experienced surfers: 8 ft SW swell, 13-second period, clean offshore and cross-offshore wind all day. Energy is pushing 1969. This is consistent, powerful, and clean. Great day.

Thursday 20th sees the swell back to 6 ft, but the morning onshore wind makes it marginal. The afternoon cleans right up with a light cross-offshore breeze, so that’s the session to target.

Friday 21st brings a clean, offshore morning with a 6 ft SW swell, period 12 seconds. The wind is a steady offshore from the WSW. Energy is 819. The afternoon stays clean but a little smaller at 4 ft.

Now, the standout of the whole 16-day period is Saturday 22nd August. Morning swell hits 16 ft, and by the afternoon it’s a massive 20 ft SW groundswell with a 16-second period and moderate offshore wind (WSW at 16 mph). The energy is off the charts at 16386 – huge, powerful, and clean. This is for experts only. The swell direction (SW) lines up perfectly with the optimum for the break. This is a true big-wave session.

Sunday 23rd still has a big 15 ft to 13 ft SSW swell, but the wind turns onshore, making it messy with cross-chop. The energy is still massive, but it’s not clean. Monday 24th has similar-size swell (12 ft) with cross-onshore winds, so it’s marginal.

Tuesday 25th sees a return to quality: 8 ft SW swell, 12-13 second period, and clean offshore to cross-offshore wind. Energy is 2362. A solid day for experienced surfers.

From Wednesday 26th onward, it’s a mix. Some days have 10 ft to 12 ft swells but with cross-onshore or onshore winds. Thursday 27th morning is a standout within that – 10 ft SW swell, 14-second period, and gentle offshore wind. Energy is 3067. That’s clean and powerful.

Friday 28th and Saturday 29th taper off in size and quality, with fresh to moderate cross-onshore winds spoiling the shape.

So, if you’re picking the one or two truly best windows: Monday 17th August morning and Wednesday 19th are excellent, but the hands-down winner is Saturday 22nd August afternoon – huge, clean, offshore, and terrifyingly good for those who can handle it.
