The Lowdown
Alright folks, Rusty here. Let’s get into it for this little patch of coast. We’ve got a bit of a mixed bag ahead, but I’ll walk you through it day by day.
Right off the bat, the first week is pretty grim. We’re looking at a solid stretch of poor surf conditions. From Tuesday the 1st right through to Friday the 4th of September, there’s just nothing worth paddling out for. The wind is howling from the NE and ENE, strong and cross or cross-on, and the water’s getting chopped up badly. It’s a write-off.
We do see a bit of a shift starting Saturday the 5th and into Sunday the 6th. The swell sticks around at about 7 ft to 7 ft from the ENE, but the period jumps up to 13 seconds, which is a proper groundswell. The combined energy is strong, hitting 2083 and 2266 on Saturday, and 1928 on Sunday morning. It’s a good sign for power, but the wind is still a fresh cross-shore, so the surface is lumpy with cross-chop. It’s only marginal conditions, and the crowds at Middles/Generals can often be there, so you’ll have company. For a more experienced intermediate, it might be worth a look if you’re desperate, but it’s not the gem of the forecast.
Monday the 7th and Tuesday the 8th are still marginal, with the swell dropping a bit and the wind backing off to a moderate breeze. The water temp is sitting at 81°F, which is about normal for this time of year, so no surprises there.
Now, here’s where it gets interesting. The real standout, and I mean the one that’s got me talking to myself, is shaping up for late in the second week. On Friday the 11th of September, we’ve got a big pulse of swell arriving. The afternoon shows 12 ft from the ENE at a 9-second period, and the combined energy is a massive 2411. It’s a strong swell. The wind is a moderate cross-shore from the NE, which is much more manageable. The file says the wind and tide are favorable, but the swell is predicted to be too big for this break. This is a serious, expert-only affair. If you’re not comfortable in solid, powerful surf, sit this one out. This is the pick of the entire 16 days, but it’s not for the faint-hearted.
Saturday the 12th keeps the size going with 13 ft from the ENE, period around 10 seconds, and energy values of 4061 and 3345. Again, wind and tide are favorable, but it’s too big for the break. Same story – expert only, and it’s a week and a half away, so keep an eye on it but don’t bank on it.
After that, things drop off fast. Sunday the 13th and Monday the 14th see the swell fading and the conditions turning poor again. By Tuesday the 15th and Wednesday the 16th, it’s tiny, with weak energy and messy wind. The last week is a blank.
So, bottom line: if you’re a confident, experienced surfer, keep your eyes on Friday the 11th and Saturday the 12th of September. That’s the big energy window. Everything else is either blown out or too small. Don’t get your hopes up for the early part of the forecast.
Stay safe out there.
