Alright folks, Rusty here. Let’s have a look at what’s on the menu at Black Rocks Jetty.
We’ve got a solid run of surf kicking off this Monday, July 13th. The combined swell energy is pumping (1876), which brings in a strong 7ft SSW groundswell hitting that exposed reef, pushing through a long 14-second period. This is not one for the grommets – that’s expert territory right there. Winds are a gentle offshore NNE breeze in the morning, keeping things clean for the experienced crew. Water temp is sitting at 76°F, which is about average for this time of year.
Things stay excellent through Monday afternoon too. The swell drops a little to 7ft from the SSW, but it goes glassy (5 km/h SE wind). That’s about as good as it gets for a session on the reef – clean and powerful.
Tuesday, July 14th, offers a step down in size to a still respectable 6ft SSW groundswell in the morning, with that same glassy-offshore combo from the ENE. The afternoon gets even smaller at 5ft and goes completely glassy. A very nice window for those who aren't chasing the big stuff.
The standout window falls on Monday morning, July 20th. We see a jump in size to a solid 8ft SSW groundswell (energy at 2399). This is big, powerful, and definitely for experts only. The catch is the wind switches to a cross-shore SE breeze, so the surface won't be perfect glass, but the raw power will have the reef throwing up some heavy, wedgy lines.
Another solid shout is the morning of Sunday, July 26th. You get 7ft of SW groundswell (1875 energy) combined with a glassy SSW breeze. That’s a quality long-period groundswell (14 seconds) on a reef with an optimum SW direction – this will be organised and punchy.
### Second Week
From the 22nd, the swell backs off a bit but still offers moments. The glassy period on the 24th afternoon looks great (6ft SSW, glassy), and the 26th repeats the Sunday glassy conditions with 7ft SW groundswell.
Bottom line: The best bets are the big, glassy mornings on July 13th and the powerful 8ft on the 20th for experts. The consistent reef break means we’ll see waves on most days, but the glassy windows around the 14th and the last weekend are where you want to be for the best shape. Keep an eye on the wind, as the cross-shore days will chop it up. This is Black Rocks Jetty, so expect a crew; the good windows will be busy.
Rusty.
