Table - best surf conditions forecast for Black Rocks Jetty over the next 16 days.
Alright, let’s talk Black Rocks Jetty. It’s a reef break, open to the southwest, and it’s very consistent. The water’s about 76°, which is pretty normal for this time of year.
Monday the 13th of July kicks off with a banger. We’ve got 7ft of SW swell, a long 14-second period, and the energy is pumping at 1876. That’s strong. Morning has a light offshore breeze from the NE, and the afternoon goes glassy – dead calm from the SSE. This is expert-only territory; anything over 8ft is for the brave, and that long period will make the reef fire. The combined energy is 1876, so expect heavy sets. This is the best of the whole window.
Tuesday the 14th backs off a bit. Morning has 6ft, still 14 seconds, glassy with an ESE breeze. Energy is 995. Afternoon drops to 5ft, 13 seconds, glassy again. Clean and surfable, but not the power of Monday.
Wednesday the 15th starts clean with 4ft, 12 seconds, glassy, but the afternoon goes to 3ft with a cross-on wind. Small and choppy. Not worth it.
Thursday the 16th and Friday the 17th are tiny. Thursday morning has 2ft, NE offshore, but weak. Friday morning shows a 17-second period, but only 2ft from the S – that long period will be weird and straight. Energy is 319. Weak.
Saturday the 18th and Sunday the 19th are poor. Saturday morning has 3ft, 13 seconds, glassy but cross-on. Sunday has 4ft, 16 seconds, but cross-on winds. Messy.
Now, Monday the 20th of July – that’s over a week away. Morning brings a massive 8ft of SSW swell, 15-second period, glassy with a 5 km/h SE wind. Energy is 3156 – that’s very strong. This is expert-only size (over 8ft), and the long period will make it powerful on the reef. Another standout, but it’s a week out. The afternoon jumps to 10ft, but the wind goes cross-on, so it’ll be a mess. That morning session is the call.
Tuesday the 21st is still solid at 8ft, but cross-on. Wednesday the 22nd cleans up with a glassy morning: 5ft, 12 seconds, WNW wind, energy 1010. Nice, clean, moderate day.
The rest of the week (23rd to 28th) is a mix of smaller swells and long-period pulses, but often cross-on or onshore. The 27th of July has a glassy afternoon with 2ft of 18-second period – very long, slow, and straight at the beach, but the reef might hold it. The 28th of July morning looks good: 5ft, 16 seconds, clean cross-off wind, energy 1015.
Overall, the standout is Monday the 13th and Monday the 20th of July mornings. Both are big, clean, and powerful. Crowds are “sometimes” here, so you might see some company. If you’re not an expert, stay away from the 8ft+ days. There are gaps of flat or poor conditions, especially around the 16th–19th and 25th–26th, but the good ones are worth waiting for.
