Nanakuli Blackrocks Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s cooking at Nanakuli Blackrocks. We’ve got a solid 16-day window with waves pretty much the whole time, starting right away on Tuesday, July 14th. The water temp is sitting at 26°, which is bang on average for this time of year, so no surprises there.

The standout days are the first few and then again around late July. We kick off Tuesday morning with a clean 2ft swell from the west, period a long 16 seconds, and a light offshore breeze from the ENE. The combined energy is moderate (493). That’s a real nice, clean groundswell, perfect for an intermediate session. It’s a rare-break spot, so when it’s on, you get it almost to yourself, though crowds can pop up sometimes. Tuesday afternoon picks up a touch to 3ft, still clean with that gentle offshore.

Wednesday the 15th holds steady with 3ft west swell, 15-second period, and light cross-offshore winds. Still clean, still fun. Thursday the 16th is another beauty – 3ft and a light cross-offshore in the morning, then the wind swings to a moderate offshore from the east at 25 km/h in the afternoon, keeping things tidy. The energy bumps up to 674 (moderate), and with a 14-second period, it’s got push.

The weekend from Friday the 17th through Sunday the 19th drops off a bit. Swell sizes dip to 2ft-2ft, and while the wind stays offshore, it’s a moderate 25 km/h breeze, which will make it a bit bumpy. The energy drops into the 100-300 range, so it’s more of a small-wave session. Monday the 20th to Wednesday the 22nd is similar, small but clean, with the occasional 3ft bump on the 21st.

Now, here’s the real stand-out second week: Thursday the 23rd and Friday the 24th. The swell direction swings to the SSW, and the period stretches way out to 20 seconds on the 23rd, then 18 seconds on the 24th. That’s very long-period groundswell. It’s only 2ft-3ft in height, but the energy is pumping – 526 and 649 (moderate). With light offshore winds and clean conditions, these are the best days on offer. This is a reef-y spot, so that long period will line up nicely. Saturday the 25th and Sunday the 26th are still fun, with 3ft-3ft swell and 16-17 second periods, but the wind picks up a bit. After that, the last few days of July fade into small, ordinary surf.

So, the pearl is definitely Thursday the 23rd and Friday the 24th of July. Light winds, clean, long period groundswell, and moderate energy. Get on it.

Rusty.
