The Lowdown
Alright folks, Rusty here. Let's break down the next couple of weeks for you.
The first week is pretty much a bust. Onshore winds and small, weak swell are the story. The real fun doesn't start until the 6th of September.
Trestles (Uppers) is the only break in the picture, a reef and point that's very consistent, so when it's on, it's on. The water temp is about average for this time of year, so nothing to worry about there.
Right now, from Tuesday morning, it's just messy. We're looking at a tiny 3ft swell from the south with a period of 11 seconds, but the wind is on it, and the combined energy is weak (289). It's a no-go. Wednesday and Thursday are more of the same – small, weak, and onshore. Friday shows a bit more energy (704), but that's a 3ft south-southwest swell with a cross-onshore breeze. Still not worth the paddle.
Things start to look interesting on the morning of Saturday, the 5th. The wind shifts to a light onshore from the southwest, and the swell picks up to 4ft from the southwest with a 16-second period. The combined energy is a solid moderate (620) and the conditions are described as "unknown" but it's a step in the right direction.
But the real standout, the one you've been waiting for, is Sunday morning, the 6th of September. We've got a 7ft swell from the south with a 13-second period, and the wind is a light cross-offshore from the north. That's clean. The combined energy is a massive 1442, which is strong wave energy. This is an excellent session for experienced surfers – that size is a bit much for beginners. The afternoon is still clean, but the wind picks up a little.
Monday the 7th is also a cracker. The morning sees a 6ft south swell, and the afternoon is a beauty: 5ft from the south, 12-second period, light cross-offshore breeze from the north. That's another clean, solid session.
Sadly, that's it for the good stuff. Tuesday the 8th gets blown out by strong cross-shore winds, and then we're back to tiny, weak, onshore slop for the rest of the window. The 16th of September shows nothing but poor conditions.
So, if you're an experienced surfer, mark your calendar for the morning of Sunday the 6th and the afternoon of Monday the 7th. That's the pick of the bunch. The rest is a long stretch of flat or choppy water.
Rusty.
