The Lowdown
Gather 'round, crew. Let's talk about Black Rocks Jetty. This is a reef set-up that's exposed to the SW, and it's a very consistent wave. The water temp is about average for this time of year, nothing wild there. We've got a solid run of surf coming through, so let's break it down.
The real standout is Saturday the 15th, morning session. We're looking at a solid 6ft of SSW groundswell with a very long period of 20 seconds. The combined energy is pumping at 3698 (moderate to strong), and with a glassy W wind, it's going to be clean as a whistle. This is prime Black Rocks Jetty, a proper reef set-up that loves that long-period groundswell direction. That is the one to circle on your calendar.
The rest of the first week has plenty on offer. Thursday the 13th kicks off with a glassy 4ft SW swell, but the energy is low (363) – a nice warm-up. Friday the 14th gets better: 6ft SSW swell in the morning and 5ft in the afternoon, both glassy with moderate to strong energy (1175 and 1534). Saturday afternoon sees the swell jump to 7ft, but the wind turns cross-on, making it a bit messy. Sunday the 16th is a mixed bag – a morning cross-shore wind on a 8ft swell, but the afternoon cleans up with a glassy 7ft SSW swell (energy 2510). Monday the 17th drops back to a nice 4ft SW groundswell, glassy and clean. Tuesday the 18th starts glassy with a 4ft S swell, but the afternoon gets a bit bumpy.
We hit a bit of a lull mid-week. Wednesday the 19th and Thursday the 20th see the swell drop to under 3ft – small and clean, but not much push. Friday the 21st picks up again with a glassy 3ft SW swell in the morning, but the afternoon gets messy with rain and cross-shore wind.
Now for the next big window. Saturday the 22nd morning is a treat: 8ft SSW swell, glassy, with strong energy (2381). That's expert territory at that size. Sunday the 23rd pushes 10ft in the morning, but it's onshore and messy. Monday the 24th cleans up with a glassy 7ft SSW swell, a solid session. Tuesday the 25th is another good one with a glassy 5ft SSW groundswell.
But the absolute highlight of the whole run, if you can wait, is Wednesday the 26th morning. We're talking a massive 12ft S swell with 12-second period and exceptional energy (5593). The wind is glassy. That is a heavy, expert-only session at Black Rocks Jetty. The afternoon turns cross-on and drops to 10ft. Thursday the 27th hangs on with a 10ft SSW swell, and the afternoon turns glassy at 8ft – another solid window for experienced surfers. The run winds down Friday the 28th with a glassy 6ft SSW swell to finish off.
Get on it.
