The Lowdown
Alright folks, Rusty here again, but this time in feet and miles. Same story – all the action is at Black Rocks Jetty. This reef breaks consistently and loves a good SW groundswell. Water temp is pretty much normal for the time of year.
We start off slow on Sunday the 6th morning. A clean 4ft SW swell, glassy, with moderate energy (659). Small but fun. The afternoon goes onshore and messy – skip it.
Monday the 7th pushes up to 7ft to 8ft from the SSW, but the wind is cross-onshore and bumpy. The energy is climbing (1738 to 2419), but the quality isn’t there yet.
Tuesday the 8th, things get real. Morning: 7ft SSW groundswell, 16-second period, cross-shore wind, energy at 4080. Afternoon: 10ft SSW, 15 seconds, 7323 energy. This is serious, powerful surf. The cross-shore wind keeps it from being perfect, but it’s a serious session for experienced surfers.
Wednesday the 9th is the absolute gem. Morning: 12ft SSW groundswell with a very long 17-second period, dead calm, glassy. Energy is huge at 7795. This is exceptional, heavy, expert-only reef surf. The afternoon stays glassy with a light N wind, still 12ft but slightly less energy (6041). Still world-class.
Thursday the 10th is still glassy, but the swell drops to 7ft in the morning and 5ft in the afternoon. Long period (14 seconds), calm wind, excellent shape. Ideal for experienced surfers wanting a big but manageable day.
Friday the 11th goes small – 4ft S swell with 11 to 12-second period. Glassy all day. Fun small-wave energy.
Saturday the 12th: morning a bit mixed, but the afternoon glass-off is clean with 4ft SSW swell. Not a standout.
Sunday the 13th: morning glassy 5ft SSW at a very long 17 seconds (1608 energy). Afternoon holds 6ft at 16 seconds (1866 energy). Glassy and clean – a lovely session for point break fans.
Monday the 14th: morning glassy 4ft SSW at a long 19 seconds (1512 energy). Afternoon gets a cross-onshore breeze and jumps to 6ft (2542 energy). Still surfable but losing polish.
Tuesday the 15th: morning glassy 7ft SSW with a solid 16-second period (2023 energy). Afternoon stays glassy with 6ft at 15 seconds (1466). Another top-tier day.
From Wednesday the 16th onward, it fades. Light cross-onshore winds and dropping swell (5ft down to 3ft by the 18th). The 18th does have a glassy, cross-off morning with 3ft but a huge 20-second period (496 energy) – super clean but tiny.
Then a final push. Saturday the 19th: 6ft SW, 16 seconds, glassy morning (1727 energy), clean cross-off afternoon (1684). Very good. Sunday the 20th stays clean with 6ft in the morning (1446) and 6ft with offshore winds in the afternoon (1296). A solid finish.
Monday the 21st rounds it out with 5ft SW, 14 seconds, glassy morning (788 energy). A nice, calm end.
The hands-down standout is Wednesday the 9th – that 12ft, 17-second glassy morning is a dream for experts. Thursday the 10th and Tuesday the 15th mornings are also top picks for a slightly smaller but still excellent session.
Rusty.
