The Lowdown
Alright, this is Rusty. Let me tell you what's cookin' for our little stretch of coast. We've got a bit of a slow start, but the second half of the outlook is where the real magic happens, so stay tuned.
The first few days are pretty ordinary. Tuesday afternoon you've got some tiny 2ft surf from the south, but it's glassy and the water is a touch warmer than normal at 76°. The combined energy is weak (112). It's surfable, but nothing to get excited about. Wednesday and Thursday mornings stay small, 1ft to 2ft, with that southwest swell trying to find its feet, but the afternoons get blown out with onshore wind, so don't bother.
Friday morning is still small, but the real story starts on Friday afternoon. That's when we see a nice jump to 5ft from the southwest, with a long period of 17 seconds. The wind goes glassy, and the energy is strong (1221). This is looking like excellent surf for experienced surfers. The crowd situation at Black Rocks Jetty can be a bit of a thing sometimes, but if you get in the water that afternoon, the conditions are going to be clean and beautiful.
Saturday sees a bit more size, 5ft in the morning, but it's a little cross-onshore. The afternoon cleans right up again with glassy conditions and 5ft surf. Sunday is much the same with 4ft waves and clean conditions all day. The combined energy is moderate (733 and 786), but the consistency is there.
Now, the standout. The real deal is from Tuesday the 8th. The swell starts to crank up, and by Wednesday morning the 9th, we're looking at a solid 12ft from the south-southwest with a very long period of 17 seconds. The wind is glassy. The combined energy is a massive 7359. This is exceptional, expert-only territory. This is a groundswell with that very long period, so it's going to have some serious power and long lulls, but it's a reef break, so it'll hold up beautifully. Absolutely not for beginners. The afternoon of the 9th holds at 10ft, still glassy, still exceptional.
Thursday the 10th is still pumping with 7ft to 5ft and glassy conditions, excellent for experienced surfers. The energy is still strong.
The second week starts to taper off. The mornings of the 14th and 15th have some size, 7ft and 5ft, but the wind is a problem. The 15th has a strong 19 mph offshore wind, which will keep it clean, but that's a lot of wind. The 16th is back down to small 3ft.
So, the pick of the entire period is hands down Wednesday the 9th. That massive, glassy, 12ft south-southwest groundswell at Black Rocks Jetty is the one to circle on the calendar. The Friday afternoon before that, the 4th, is also a beautiful, glassy session for the stronger paddlers.
Signing off, Rusty.
