The Lowdown
Alright, surfers, Rusty here. Let’s cut through the noise and get into what this stretch has in store for us. We’ve got a sixteen-day window, and it’s a bit of a mixed bag. The pattern starts off pretty flat and messy, then builds into some serious size before cleaning up for a few windows of hope. Keep your expectations in check early.
The early part of this run is looking pretty grim. From Friday the 21st right through to the morning of Monday the 24th, it's basically a no-go. We're looking at small, weak swell mixing with onshore and cross-onshore winds, so it's going to be lumpy, choppy, and just plain uninviting. This isn't the time to be paddling out.
Things finally start to get interesting on Monday the 24th. A solid groundswell rolls in from the SSE with a long 19-second period. The energy jumps right up to (1382), which is a big step up from the weak stuff. The morning has light cross-onshore winds, so it's bumpy, but there's something to work with. That afternoon, the swell jumps to 7ft with the same long period, but the onshore wind picks up and it gets messy. Unless you're desperate, I'd wait.
Tuesday the 25th is where the size really shows up. We're looking at a massive pulse, with energy readings in the thousands (3861 in the morning). It's big, it's powerful, and it's going to be challenging. By the afternoon, we're looking at a solid 10ft of south swell. This is well overhead, and while a long-period south groundswell can be good, at this size, it's only for experts. For most of us, this is a day to watch from the sand.
The rest of that week is nothing but a write-off. The wind swings onshore and it gets stormy and rough. The swell drops a bit but it's still on the bigger side, and it's just a mess. From Wednesday the 26th through Friday the 28th, we've got rain, strong winds, and poor quality surf. Not worth the aggravation.
The weekend of the 29th and 30th still isn't anything to write home about. The swell backs off, but the winds stay poor. However, there’s a little light at the end of the tunnel for Sunday afternoon, the 30th. The wind goes glassy, and the surf, while small at 4ft, should finally be clean. It’s a session for a longboard, not a performance board.
Now, here’s where I get a little excited. Monday, the 31st of August is a standout. We've got a 5ft swell from the SSE, but the magic is in the wind. It’s blowing offshore from the northwest, which will groom those waves to perfection. The energy is solid (818) and the period is a healthy 13 seconds. This is your window for quality, clean waves. This is the best day on offer, hands down. The forecast is still over a week away, so keep an eye on it, but this one has real promise.
Following that, we have another gem on Wednesday, the 2nd of September. The morning is looking at a moderate offshore wind from the NNW with 4ft of ESE swell. It's not huge, but it will be clean and fun. The energy is still moderate (814). This is another one to put in the diary.
The run-out from there sees the swell fade and winds turn onshore again. The end of the window on Friday the 4th and Saturday the 5th has some size returning from the south, but the wind and rain look like they'll ruin it. It's not worth getting your hopes up for those final days.
One last thing: the water temp at the start of this, around the 21st, is a toasty 81°, which is about normal for this time of year. So no need for a thick wetsuit.
Keep your eyes on the 31st of August and the 2nd of September. Those are the days to plan around.
Rusty, out.
