Nanakuli Blackrocks Surf Forecast and Surf Report

G’day, Rusty here. Let’s talk about what’s cookin’ at Nanakuli Blackrocks for the next couple of weeks. The water temp’s about what you’d expect for this time of year, so no chills or toasty surprises. It’s not a blockbuster stretch, but there are a few moments worth setting your alarm for.

We start on Thursday, 13 August. There’s a south swell running at about 4ft, but the period is a solid 16 seconds – classic groundswell energy (883). The wind’s blowing offshore from the ENE, so the surface is clean. For a spot that rarely breaks, this is a rare chance to score some lined-up reef waves. Just be aware, crowds are possible, so you might have to share.

Friday, 14 August, keeps the same wind, but the swell drops to 4ft, still from the south with a 14-second period. The energy is moderate (521). It’s rideable, but nothing special.

Saturday, 15 August, gets tricky. The swell shrinks to 3ft, and the wind jumps to 25 mph from the ENE. It’s offshore, but that strong breeze makes paddling a real chore. I’d sit this one out.

Sunday, 16 August, sees a spike to 6ft from the SSE, but with a shorter 11-second period. The energy picks up (946), but the wind stays strong, and there’s a risk of thunderstorms. This one’s more for the kite surfers than the paddle crowd.

Now, from Monday, 17 August, to Wednesday, 19 August, the swell drops to 2ft to 3ft, but the wind lightens up from the ENE, staying offshore. Conditions are glassy to clean. The waves are tiny, but for a rare-break spot, you might snag a longboard wave. Not a standout, but a pleasant little window.

The real standout is Friday, 21 August. The swell is only 2ft from the southwest, but the wind goes dead calm – glassy as a mirror. The period is a gorgeous 17 seconds, so the energy (295) is pure quality. For a spot that rarely shows, this is the day. Clean, peeling waves with no wind to mess ’em up. Crowds are still possible, but with such tiny surf, it’ll be a quiet session.

After that, from 22 August through 28 August, it’s a long stretch of small, clean surf. Swell stays between 2ft and 3ft from the south/southwest, with offshore winds most days. Energy is low to moderate (242 to 530). The 26th has a bit more pop (530) and a “very good” call, but still tiny. Bottom line: if you’re keen, aim for the 21st – it’s the quiet gem in a mellow forecast.

Rusty, signing off.
