The Lowdown

Alright, Rusty here. Let's get into it.

Right off the bat, the surf is pumping, but this is not a spot for the faint of heart. We're looking at a solid run of swell, but the wind is going to be the main character for the next week or so, and it's a grumpy one. It starts with a bang, but the quality is going to be a struggle.

We kick off this Sunday, the 23rd of August, with a massive 15ft swell out of the WNW, but the wind is a full-on gale from the west at 40 mph. It's a washing machine out there. The combined wave energy is enormous at 3781, but it's a no-go for surfing. The same goes for Monday, the 24th. The swell drops a touch to 10ft from the west, but the wind is still a strong breeze. The notes say it's too big for this break, and I agree. It's a shame because the swell is a long-period 15-second groundswell, which would be something special if it was clean.

Tuesday, the 25th, is still a write-off with 7ft+ swell and strong cross-shore winds. The whole first week is a write-off, honestly. The wind just doesn't let up. It's not until Thursday, the 3rd of September, that we get a glimmer of hope. The swell drops to 5ft from the west, and the wind is a light cross-off. It's still marginal, but it's the first day we could even think about paddling out.

Now, the real standout is the morning of Friday, the 4th of September. The swell drops to a clean 3ft from the west, but the wind is a glassy 6 mph cross-off. It's a light breeze, which means the surface will be buttery smooth. The combined energy is weak at 600, but for a clean, fun wave, this is your window. It's a 13-second period, which isn't huge, but with zero wind, it'll be a joy. This is the best on offer for the entire forecast.

Looking further out, the morning of Saturday, the 5th of September, shows another big pulse of 12ft from the west. The wind is a slight air from the SW, which is perfect. But again, the notes say it's too big for this break. It's a classic case of the swell being too powerful for the setup.

The water temperature is sitting at 57°, which is about normal for this time of year, so no wetsuit surprises there.

So, to be blunt, it's a rough start. The first ten days are mostly a battle with the wind and oversized swell. The one true standout is the Friday morning on the 4th of September. It's small, but it's clean. If you're a seasoned surfer, the big swells might be a challenge, but for most, it's a waiting game.

Rusty.
