Nanakuli Blackrocks Surf Forecast and Surf Report

Alright folks, let's settle in and look at what the next couple of weeks have in store. We're focusing on the west side, on a spot called Nanakuli Blackrocks. The water temp right now is sitting at 80°, which feels about what you’d expect for this time of year – no real surprises there.

The big story coming in is the wind. It’s going to be coming out of the East-Northeast consistently, and that’s going to lay down some proper offshore grooming. That’s the kind of friend you want for a smooth, clean face.

So, we kick things off this Saturday, July 4th. We’ve got a solid long-period groundswell from the south – 21 seconds between bumps – and with that combined energy reading at 721, there’s some real weight behind it. Expect chest to head high sets at around 2ft to 3ft. The morning is the sweet spot, with that clean offshore breeze. I’m calling Saturday morning the real standout of this first weekend. Heaps of fun, but fair warning: this break is listed as "rarely breaks," so when it does, it's a special treat.

Moving into Sunday and Monday, we see the height ticking up a notch. Swell from the SSW at 3ft, but the period starts to drop off through Monday. The wind stays offshore, so it'll be clean, but the wave quality won't have that same punch as Saturday. By Tuesday, the swell is fading a little and the period is down around 14 seconds. Still some lines coming through, just losing a bit of that grunt. There’s a gap of a few days with just ordinary or poor conditions from Wednesday afternoon the 8th of July through Friday the 10th of July as the swell dips to below 2ft.

Now, hang on. The 11th of July (Saturday) picks up again. The wind stays offshore and we see a new pulse from the SSW with a period jumping back up to 18 seconds. The energy kicks back up to 357 that morning. Good signs.

The real second standout, and possibly the best stretch of the whole outlook, builds from the 13th of July, Monday. The swell is still a solid 3ft, but now it's starting to swing more westerly with a period of 15-16 seconds. The combined energy numbers are pumping, hitting 854 on the 15th of July, Wednesday morning. The wind stays offshore and light. This is the kind of window where Blackrocks might just turn it on with long, clean walls. Wednesday the 15th of July is looking like the top pick of the whole 16-day run.

Beyond that, through the 17th of July, we still see waist to chest high sets from the west, with clean conditions, before things taper off into more ordinary conditions over the weekend of the 18th. Keep an eye on that 19th of July though – the period is back up to 20 seconds, showing a new south swell kicking in, but that one’s a little further out.
