The Lowdown
Alright, Rusty here. Let’s talk about Black Rocks Jetty. The water temp is 75°F, which is pretty standard for this time of year, nothing weird going on.
We’ve got some swell on the way starting Sunday the 13th. You’ve got a 6ft SSW groundswell with a very long 16-second period, packing a bunch of energy (1857). But the wind’s blowing cross-onshore, so it’s going to be choppy. Not the best start.
Monday the 14th is a write-off – smaller swell and onshore wind.
The real show starts Tuesday the 15th. The morning is still a little off, but Tuesday afternoon is a standout. We’re looking at 6ft of SSW groundswell (17-second period) and a glassy surface. The energy is strong at 2671. This is excellent surf for experienced folks who know what they’re doing.
Wednesday the 16th brings some size. The morning has an 8ft SSW groundswell with a 15-second period – that’s big and a bit unruly with onshore wind. The afternoon cleans up with a 8ft SSW swell and offshore NE wind at just 3 mph. For the experienced crew, that’s some raw, clean power.
Thursday the 17th stays glassy with a 5ft S swell. Nice, manageable, and clean.
We hit a bit of a slow patch on Friday and Saturday the 18th and 19th. The swell drops off, but the wind stays light.
Swell picks back up Sunday the 20th and Monday the 21st, though it's smaller at 3ft to 4ft with clean, glassy conditions. Good for logging.
In the second week, things look good again. Thursday the 24th is a big call. The afternoon shows a 5ft SSW groundswell with a very long 20-second period, and the energy is huge at 2022. The wind is onshore, so it won't be perfect, but that long-period groundswell will wrap deep onto the reef. Keep an eye on it.
Friday the 25th brings a 7ft SSW swell, but the wind is cross-onshore again, making it bumpy.
The forecast wraps up with a strong finish on Sunday the 27th. The afternoon session has a 6ft SSW groundswell with glassy conditions and solid energy (1257). Excellent for the experienced surfer.
Finally, Monday the 28th stays clean and glassy with a 5ft SW swell. A solid, consistent way to end the run.
This spot is very consistent. The main windows are Tuesday the 15th afternoon, and that Sunday the 27th afternoon. Get on it.
