The Lowdown

Alright, folks, it’s Rusty. Let’s talk about what’s coming.

We’re zeroing in on Black Rocks Jetty. It’s a reef break that’s almost always breaking, which is a good thing. The water temperature here is feeling like a typical late summer, nothing crazy.

The week ahead is full of potential. We kick things off on Wednesday the 16th. The morning is a bit meh, but the afternoon is where it’s at. Wednesday afternoon, we’ve got a solid 8ft SSW groundswell with a 14-second period. The wind goes flat calm, glassy. The wave energy is strong (2350). This is premium, expert-level surf. The swell direction is right for the break.

Thursday the 17th is another gem. The swell drops to a clean 5ft from the south in the morning, still with a nice 13-second period. Glassy again. The energy is moderate (878). The afternoon stays glassy as it backs off a touch. Really clean, fun waves.

Then we hit a lull from Friday the 18th through Sunday the 20th. The swell gets small, 2ft to 4ft. Winds are light on the weekend, but the wave energy is low (300-470). There's something to ride, but not the main event.

Monday the 21st starts to build again. The morning is a bit onshore, but Monday afternoon brings a new 5ft SSW pulse with a 15-second period. The wind goes glassy, and the energy pops back up to a solid 922. A very good afternoon session.

Tuesday the 22nd keeps the quality with glassy conditions and 3ft to 3ft SSW swell, with a gorgeous 17-second period in the afternoon (energy 780). Very clean lines.

Now, here’s the absolute banger of the outlook. Wednesday the 23rd. The afternoon is the session. We get a 5ft SSW swell with a monster 20-second period. The wind drops to a dead calm, glassy. The wave energy is very strong (2470). This is proper groundswell hitting a reef. It’s for experienced surfers only. This is the one.

Thursday the 24th is a perfect encore. The morning holds at 5ft SSW with a 16-second period and glassy winds (energy 1438). The afternoon is just as clean at 5ft with a 15-second period. Both sessions are top-tier for advanced guys.

After that, we get a bit choppy. Friday the 25th is blown out. Saturday the 26th has small clean waves in the morning but gets cross-onshore and poor in the afternoon. Sunday the 27th morning has clean 3ft waves, but the afternoon gets a bigger 5ft SSW pulse with cross-shore winds. Not as clean.

For the following week, there’s more to like. Monday the 28th is a solid call. Clean conditions with a 6ft SSW swell in the morning and a nice north cross-offshore breeze (energy 1124). This is excellent for experienced surfers. Tuesday the 29th stays clean in the morning with strong energy (1264) but gets more mixed later.

If you’re looking ahead, Thursday the 1st of October is another good one. The morning has a 4ft SSW swell with a 16-second period, glassy conditions, and excellent quality for experienced surfers (energy 1178). It's a way off, so keep an eye on it.

So, the best of the best is that Wednesday the 23rd to Thursday the 24th window. The first week is a ripper. The second week has Monday the 28th and Thursday the 1st of October as your best bets.

Rusty.
