Nanakuli Blackrocks Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s coming up for Nanakuli Blackrocks.

First off, the water temp is sitting at 80°, which is about 0.5° warmer than normal for this time of year – nothing crazy, just your typical summer warmth.

Now, full honesty: this spot is listed as “rarely breaks,” and that’s the story for the next 16 days. There’s no standout session here. The first few days, from July 11 right through to July 13, are a tough watch. We’ve got tiny swell, mostly 2ft to 3ft from the SW, with a very long period of 18 seconds dropping to 15 seconds. That long period means the wave energy is drawn out, but the size is just too small to get excited about. The combined energy is weak, sitting between 260 and 459 (weak to moderate), and the swell direction is WSW, which isn’t the optimum for this spot. Winds are offshore ENE, so the surface will be clean, but there’s just not enough push.

The middle of the week, July 14 and 15, sees a small bump in quality. Swell hangs around 2ft to 3ft, shifting to a W direction, and the period is still long at 15-16 seconds. The combined energy climbs into the moderate range (496 to 573). Winds stay light to gentle offshore, or cross-off on the 15th, so the conditions will be clean. This is the best stretch, but it’s still not a big wave day. The swell is too small for any real power, and the break is inconsistent.

From July 16 onward, the swell drops off again. We see a mix of SSW and S swells, mostly 2ft to 3ft, with periods shortening to 13-14 seconds at times. The combined energy drops back to weak or low-moderate (89 to 485). The wind stays offshore most of the time, so the surface will be clean, but the waves are going to be tiny and very ordinary. There’s a little spike in energy on July 23 with a 20-second period SSW swell, but the height is only 2ft – all length, no punch.

For a spot that rarely breaks, this is a long stretch of marginal surf. The best bet is the morning of July 15 or the morning of July 16, when the swell is a touch bigger and the wind is light. But if you’re looking for a proper session, there’s nothing here that’ll get your heart racing. It’s a quiet window.

Rusty.
