The Lowdown
Alright, let’s break it down, surfer style.
Right now, we’re in for a bit of a flat spell. Don’t even bother until Friday – it’s just not happening. The ocean’s got nothing for us.
But hold on, because the end of the month and the first few days of September are looking like the real deal. We’ve got a proper groundswell coming in from the southwest with some serious period on it. This isn’t just junk; this is the kind of energy that gets a point break like Quatro-Once (411) absolutely firing. Swell heights will be pushing 5ft, and the power behind it is legit – we’re talking energy values in the four-digit range (1181, 1179, 1117), which means there’s some serious water moving.
The winds are going to mess things up a little for the first few days, blowing onshore and making the surface choppy. But it cleans right up on Saturday the 29th. If you can get out early, you’ll be rewarded with clean conditions and a building swell.
The absolute best window is from Sunday the 30th right through to Tuesday the 1st. The swell holds in that 4-5ft range, and the winds are light, with some completely glassy, perfect mornings. This is the time to be in the water. Expect some crowd factor, but it’s worth it. Monday the 31st is the pick of the bunch – glassy, clean, and the point will be reeling off perfect lines. This is one of those sessions you’ll be talking about.
Water temps are pretty normal for the season, nothing to worry about.
After that, it backs off in size but keeps the quality for a few more days. Still worth a paddle, but if you want the big waves, that weekend is your target.
Rusty out.
