The Lowdown
Alright, Rusty here. Let's talk about what's on the menu at this spot.
It’s all about Black Rocks Jetty for the next couple weeks. This is a very consistent reef break, so it doesn't stay flat for long. The water's sitting at about 77°, which is a touch warmer than usual for this time of year – feels good.
We start on Thursday, August 6th with a glassy morning and a clean 3ft SW groundswell. The energy is moderate (299). That afternoon the swell holds at 3ft but with glassy conditions again.
Friday the 7th starts clean with 2-3ft SW (250 energy) and a light offshore, but the afternoon crumbles as the wind goes cross-onshore and the swell drops to a pathetic 1ft.
Find the trigger date: Saturday the 8th. Saturday morning is a dreamy 4ft SW (779 energy) with glassy wind. The afternoon pushes to 4ft SW (937 energy) and stays glassy. This is the start of a really good run.
Sunday the 9th gives you consistent 4ft SW swell (619 energy) with glassy conditions all day. Perfect.
Monday the 10th gets a bit of a side-shore breeze, but the 4ft swell (935 energy) is still there. Tuesday the 11th and Wednesday the 12th are right back to glassy, with 4ft SW swell (731 energy) on Wednesday.
The first real standout is Friday, August 14th. Friday morning offers a solid 6ft SSW swell with a strong energy of 1596. The wind is glassy. This is excellent, punchy surf for experienced surfers.
The big one, the one to circle, is Saturday, August 15th. Saturday morning packs a 5ft SW swell with a very long 20-second period and an enormous 3650 combined energy, all under a glassy sky. The afternoon shifts to a 6ft S swell (4839 energy) with clean offshore winds. This is the best session on the charts – powerful, long-period groundswell and perfect conditions. It’s for the experts only.
Sunday the 16th gets big at 10ft SSW but with a cross-onshore wind that will chop it up, so it’s a rough one even for the experienced.
From Monday the 17th onward the swell fades back to the 3-4ft range with glassy mornings, through to Thursday the 20th and Friday the 21st, but the real magic was that mid-month window.
Rusty.
