Diamond Street Surf Forecast and Surf Report

Yo, Rusty here. Let's get into it for Diamond Street. Straight up, this is a tough outlook. The next 16 days are looking pretty grim for quality waves. We've got a bit of a pulse coming through on Sunday the 6th, but otherwise it's a whole lot of nothing for most of the period. Let's break it down.

The first real chance for a surf starts on Friday morning, September 4th. We're looking at a small 3ft SW groundswell with a long 17-second period pushing in. Combined energy is at 624, so there's some oomph there. But the big catch is the wind is light offshore from the W, which will keep it clean. The trouble is the tide or something else is making it marginal, so it's not a slam dunk. The water temp is about average for this time of year.

Through Saturday the 5th, it's more of the same, a little 3ft to 4ft S/SW swell, but the wind swings cross-onshore, chopping it up. Not great.

Now, Sunday morning, September 6th, is your best bet for the whole window. Swell bumps up to a solid 7ft from the SSW with a 14-second period. Wave energy is strong at 1422, and the wind is a cross-offshore breeze from the N at 16 mph. The report says clean. That's the standout. This is a legitimate session for a confident surfer. Afternoon sees the wind turn and it gets messy.

From Monday the 7th onward, it's a slow slide downhill. Swell starts to drop from 6ft, and the wind stays mostly cross-onshore. The energy levels drop into the three-digit range quickly. By mid-week, from September 9th, it's getting marginal at 4ft or less.

Then comes the dead zone. From Friday the 11th of September all the way through to Wednesday the 16th, the surf is officially poor. Swell drops below 3ft and the guidance is clear: poor surf conditions. That's a solid 5 days of nothing worth paddling for. The combined energy is weak, down in the 100-300 range.

There's a tiny flicker of life on Thursday the 17th of September, with a very long 22-second period 1ft SW groundswell. Energy jumps to 331, but it's tiny. That's more of a long-period ripple than a wave. And then again on Friday the 18th, a similar small 2ft, 20-second period swell shows up. Both of these are marginal at best, and the weak size means a 22-second period groundswell will likely just roll right through without breaking properly at a beach break like this.

So, overall, your one shot for a decent wave is Sunday morning, September 6th. After that, put the board away for a good week.

Rusty.
