The Lowdown
Alright folks, Rusty here. Let's get into it. We've got a solid run of swell coming our way, but it's not all smooth sailing. The real standout is the opening day, so let's get that wetsuit ready.
The first real action kicks off Wednesday, September 9th. The big story is Black Rocks Jetty getting absolutely hammered. We're looking at a serious 13ft SSW groundswell with a very long 17-second period. The combined energy is huge (8708), and the wind is glassy. This is a reef break, it's very consistent, and it's exposed. The water is a touch warmer than normal at 76°F, about 2°F above average. But listen, at 13ft, this is for experts only. If you're not one, don't even think about it. The Wednesday afternoon session is still pumping at 12ft, glassy, and clean.
Into Thursday the 10th, the swell drops but still holds a solid 7ft SSW groundswell in the morning with glassy conditions. That's a great shout for experienced surfers. The afternoon eases to 5ft, still clean.
Friday the 11th is a big drop-off, with 4ft S swell, but the afternoon goes offshore with a NNE breeze. It'll be clean, but small.
Saturday the 12th and Sunday the 13th see a pick-up again. Saturday is a fun 5ft SSW with glassy mornings. Sunday morning is the pick of the weekend with a 5ft SSW groundswell, a 17-second period, and glassy conditions. The energy is back up (1796). The afternoon on Sunday gets a bit of a cross-on breeze, so surf it early.
Monday the 14th and Tuesday the 15th are a bit messy with cross-onshore winds. The energy is still there, but the quality drops. Tuesday afternoon, however, goes glassy again with a 6ft SSW groundswell – a sneaky good session.
Wednesday, September 16th is a standout morning. We get an 8ft SSW groundswell with a clean offshore cross-off breeze from the North. That's a solid, powerful swell and good wind. This is a big one for experts.
The following week from Thursday the 17th into the 24th is a mixed bag of smaller swells and onshore winds, with a few glassy windows. Wednesday, September 23rd afternoon is a beauty: 7ft SW groundswell, glassy, and clean. Then Thursday the 24th sees a solid 10ft to 12ft SSW swell, but the wind is cross to onshore, making it a bit of a battle. That setup looks more interesting for kite surfing than paddle surfing.
So, the best on offer is hands down Wednesday, September 9th for the big, clean, expert-level swell. The second pick is Wednesday, September 16th morning for another solid pulse with clean offshore wind. Get after it.
Rusty.
