Rainbow Rocks Surf Forecast and Surf Report

Alright, Rusty here. Let's talk about what we've got comin' up for Rainbow Rocks.

Right off the bat, I gotta be straight with you—this 16-day window is a rough one. For the next week and a half, we're looking at a whole lot of wind and swell that just ain't lining up. The waves are there, but the conditions are messy. We do have a solid pulse of energy mid-period, but you'll need to pick your moments.

The early part of the outlook is a write-off. Monday the 10th through to Wednesday the 13th have got some serious size—10ft on Monday and Wednesday afternoon with a massive 1412 combined energy—but the wind is a stiff cross-off from the NNW at 22 mph. It’s clean, sure, but that's more of a kite-surfing setup than a good paddle session. The period is a short 7 to 8 seconds, so it’s choppy, fat, and ugly. Don't bother.

We get a slight improvement on Thursday the 14th with the swell dropping to 5ft and the wind easing to a light breeze from the NW. The period is still short at 8 seconds, but the energy is a moderate 536. It's still cross-shore, so it's not gonna be glassy perfection, but it's the best we've seen so far. That Friday the 15th is a weird one—a tiny 2ft swell from the SSW with a very long 18-second period and a massive 503 energy. That's a lot of energy for not much height. It’ll be fat, straight, and only really works at a point or reef, not a beach-and-reef setup like this. The wind is light and cross-shore, so it'll be clean, but it's a mushy, inconsistent mess.

That Saturday and Sunday are similar—small, long-period groundswell with light winds, but nothing with any punch. The best chance in this whole fortnight is shaping up for Wednesday the 19th in the morning. We have a glassy ocean, a light SW breeze becoming glass, and a 2ft SSW swell with a 16-second period. The energy is 494. It’s small, sure, but with zero wind and a very long, clean swell, it’ll be the most user-friendly, organized wave of the period. It's not a standout for power, but for pure, clean fun, this is it.

After that, the forecast gets punchy again on Thursday the 20th afternoon and Friday the 21st afternoon. We see a 7ft to 8ft NW swell with a short 6 to 7-second period and a cross-off wind from the NNW at 9 to 12 mph. The energy jumps to over 900. It's big and strong, but the period is terrible, so it’ll be a crumbly, pitching shorebreak. Only for the experienced crew.

The last couple of days of the outlook drop off into small, weak, and messy conditions.

So, the standout? It's that Wednesday morning, the 19th of August. It's not gonna be huge, but with glassy conditions and a clean swell, it'll be the most enjoyable, least frustrating session on offer. Everything else is either blown out, too big and short-period, or too gutless.

Stay patient, mate.
