The Lowdown

Alright, grab ya cuppa, let's have a look what's on the table. I'm talkin' about Quatro-Once (411), a consistent point break that's known for welcoming beginners, sittin' exposed to that south-southwest energy. The water temp's about average for this time of year, so nothin' wild to report there.

Over the next week, we've got a bit of a slow start, but the quality's real nice. Tuesday the 18th kicks off with a steady 3.6 ft swell from the SW, with a solid 14-second period. That's a proper groundswell, and the combined wave energy is pumpin' at a moderate 567. The wind's a light cross-offshore, so things are lookin' clean for a Tuesday morning session (Big Island).

Wednesday the 19th is the standout of this first week. We're talkin' glassy conditions in the morning – a total zero on the wind – with a 3.3 ft SW swell and that same 14-second pulse. The energy is still chunky at 529. For a point break, that's about as good as it gets for a learner or a cruiser. Glassy, consistent, and that long period will wrap in beautifully. Keep an eye on the afternoon, though; a bit of cross-on wind messes with the surface.

Thursday the 20th through to the weekend holds more clean windows, but the swell tails off a touch. Friday the 21st is a solid shout, with 4.3 ft and glassy conditions both morning and afternoon, and a moderate 466 energy reading. Really fun, clean surf for those days.

We hit a bit of a lull over the weekend and into the start of the next week. The swell drops right down, and while there are a few glassy early mornings (Sunday the 23rd, Monday the 24th), the height's only around 1.6 ft to 2 ft. It's still surfable, but you'll be workin' hard for little waves.

Now, hold onto your board for the end of the run. This is where it gets promising, but it's a long way out. Sunday the 30th of August is the biggest highlight of the whole forecast. We've got a proper 5.2 ft SW swell rollin' in, with a 16-second period and glassy conditions in the morning. The combined energy skyrockets to a very strong 1484. That's expert territory though – over 8 ft it's for the big dogs, but at 5.2 ft on a point, it's a hell of a lot of fun for anyone comfortable in that size. That Sunday morning is the big call, but it's two weeks away, so don't lock it in just yet.

Then Monday the 31st of August and Tuesday the 1st of September still offer decent, clean 4.9 ft and 3.6 ft surf respectively, before it fades out again early in the second week.

Bottom line: The first week is consistent and clean, with Wednesday the 19th bein' the pick. The end of the forecast holds the biggest, most powerful swell, but it's still a maybe. Stay stoked.
