Black Rocks Jetty Surf Forecast and Surf Report

Alright, let’s get into it. There’s plenty of swell on the cards, but you gotta pick your moments.

We’ve got a bit of a wait for the real juice, but the opening stanza this Wednesday afternoon at Black Rocks Jetty is already looking serious. We’re talking a solid 12ft of SSW swell, with a long 17-second period. That’s proper groundswell, and with the glassy conditions and the water temp sitting at a touch warmer than normal for this time of year, it’s going to be an exceptional session for the experts. The energy is strong too, so there’s plenty of push behind it. This is one of the standouts of the whole run – expert crew only for this one.

After that initial punch, it pulls back a bit. Thursday morning still has a very decent 7ft of SSW swell with a 14-second period and clean glass, but the scores drop off. It’s still excellent for experienced surfers, just not as wild. Thursday afternoon eases to 5ft, still glassy, and it’s good, but not a standout.

Friday drops further to a smaller 4ft, and while the morning is glassy, the afternoon gets a bit iffy with an onshore breeze. Saturday sees a return to a more fun size, around 5ft with clean conditions, and Sunday morning is looking nice with 5ft and a long 17-second period. That Sunday morning session is a good one, but the afternoon gets a little lumpy with a cross-onshore.

The start of the following week gets messy. Monday sees the wind pick up, and conditions turn choppy. Tuesday has some size but the conditions are questionable, with an onshore wind and the waves not looking clean.

Then we hit the second standout. Wednesday the 16th. We get a jump back up to 8ft of SSW swell, a 15-second period, and it’s glassy. The energy is pumping, and it’s an excellent call for experts. This is the other real highlight on the board. We’re looking at the kind of day you’d rearrange your schedule for.

After that, it drops back down. The end of the week sees smaller surf, with Thursday and Friday offering clean but much smaller waves around the 3ft to 6ft mark. It’s a bit of a lull, with some cross-onshore winds making the weekend look average.

There’s a bit of a flat spell there, a few days where it’s really not worth paddling out unless you’re desperate. The swell looks weak and the winds aren't helping.

But hold on, there’s a late push. Around the 23rd, we’re looking at another significant pulse. The 23rd afternoon shows a solid 8ft of SSW swell, a 17-second period, and glassy conditions. This is a long-range call, so it’s promising but we don't have the same certainty as the earlier days. It’s a similar story for the 24th, with good size and clean conditions in the afternoon.

So, overall, it’s a good run for the experts. The two big standouts are the opening Wednesday the 9th, and that Wednesday the 16th. The long-period swell is going to make the reef break at Black Rocks Jetty (Big Island) work well, as it’s a spot that can handle that sort of energy. With crowds “sometimes” in the water, you might have some company on the good days, but it’s not going to be a circus. Keep an eye on that final pulse around the 23rd and 24th; it could be the best of the lot if it comes together.
