The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Black Rocks Jetty.
We've got a bit of a slow start, but nothing to worry about. Sunday the 19th is a write-off with some drizzly, cross-offshore wind and only small, marginal waves. The water is a touch warmer than normal for this time of year, sitting at 76°F.
The real action kicks off on Monday the 20th. We're looking at a solid SSW groundswell coming in at 7ft with a long 14-second period. The combined energy is strong (1987), and the morning is glassy with a light NNW breeze. This is proper, clean, powerful surf – definitely for the experienced crew only, as it's over 5ft. The afternoon stays glassy with a slight wind shift, keeping it just as good.
Tuesday the 21st keeps the quality high. The swell drops a touch to 6ft, still from the SSW with a 12-second period. The energy is still strong (1112), with glassy conditions in the morning and clean cross-offshore winds in the afternoon. This is beautiful, consistent surf.
Wednesday the 22nd is another standout. The swell is 5ft from the S, period 13 seconds, and the morning is dead calm – glassy as it gets. The energy is strong (1045). This is a session you'll be thinking about for days.
Thursday the 23rd and Friday the 24th see the swell drop a little to 4ft, but the mornings are glassy with a long-period SW groundswell coming in on Friday. The energy is moderate (772). These are great for a longboard or a funboard, clean and easy.
Saturday the 25th afternoon cleans up nicely with glassy conditions on a 4ft SSW swell.
Now, there's a bit of a rough patch from Sunday the 26th morning with strong onshore winds ruining the shape. That lasts through Monday the 27th, where we get a big jump in size (8ft) but the cross-onshore wind makes it a mess. This is a session for the kite crew, not the paddle crew.
The real payoff comes on Tuesday the 28th. The swell is 8ft from the SSW, period 15 seconds, and the morning is clean with a light NW cross-offshore wind. The energy is very strong (2705). This is big, powerful, and angry – experts only. It's a beast of a session.
Wednesday the 29th stays big at 7ft, but the wind is a bit sketchy. Thursday the 30th morning cleans up again with glassy conditions and 6ft of swell.
Hold onto your hats for Friday the 31st. This is the clear winner of the whole forecast. The morning is glassy, the swell is a solid 8ft from the SSW with a 16-second period, and the combined energy is massive at 3110. This is the kind of day that makes you call in sick. It's a heavy, powerful, long-period groundswell that will be reeling down the reef. Experts only, but it will be world-class.
The first week of August sees a return to some smaller, cleaner conditions. Saturday the 1st is a bit mixed, but Sunday the 2nd is a gem with glassy conditions and a 5ft SSW swell (period 17 seconds, energy 1514). Monday the 3rd finishes off with a clean, glassy morning on a 4ft swell.
The Bottom Line: The absolute best of the best is the morning of Friday the 31st of July. The morning of Tuesday the 28th is a close second. The entire run from Monday the 20th through Wednesday the 22nd is also top-tier. Get on it.
Rusty.
