The Lowdown
Alright folks, it’s Rusty here. We’ve only got one spot on the radar this time around, Chadbourne Gulch, and it’s going to be a bit of a mixed bag over the next couple of weeks.
Right now, things are looking pretty average. We’ve got some swell coming in at around 4ft from the SSW with a very long 16-second period, but the wind is on it and the combined energy is high at (1008). The conditions are described as marginal, so don't get your hopes up for the immediate sessions.
The coming week is a bit of a struggle. Monday and Tuesday see the swell dropping off to under 3ft, with periods still long but the energy fading fast (down to 300). The wind keeps messing with it, mostly cross-on. By Wednesday we bottom out with tiny 2ft to 2ft waves. It’s quiet.
There’s a little flicker of hope on Thursday the 3rd of September morning – the swell pops back up to 3ft from the SW with a 19-second period and combined energy of (950). It’s still just a "marginal" call though. The real standout, the one session to actually pencil in, is Sunday the 6th of September. We get about 3ft of SSW swell, but the wind goes glassy. Light airs, clean conditions, the energy is modest at (589) but the surf should be super clean and fun for a log or a mid-length. That morning and afternoon both look glassy – that's your window.
Later on, the 11th of September Friday afternoon and the 12th of September Saturday bring a bigger pulse. We’re talking 6ft to 7ft from the NW. That’s getting solid, and on Saturday the wind goes glassy again, which is prime. But the period is short at 7 to 8 seconds, so it’ll be a bit crumbly and powerful, more for the experienced crew. The energy is well into the moderate range (903 to 1143), so there’s push behind it.
Chadbourne Gulch is a fairly consistent spot, but it’s not going to be firing every day. The water temp is about average for this time of year, nothing weird going on there. Crowds can show up sometimes, so keep an eye out.
Overall, the best bet is the glassy Sunday the 6th for clean, manageable waves, and then the bigger glassy Saturday the 12th for the more advanced lads looking for some punch.
Take it easy,
Rusty
