The Lowdown
Alright, this is Rusty. Let's have a look at what's on the table for the next couple of weeks.
First off, it's a bit of a slow start. The immediate forecast is pretty grim with poor conditions and no real surf to speak of for the first few days. Sunday the 13th is a write-off – messy and choppy. Monday the 14th sees some size but it's too big for this spot and the wind is all wrong. We're looking at a couple of days of waiting.
The first real standout window comes on Tuesday afternoon, September 15th. Chadbourne Gulch is going to be firing for the experienced crew. We've got a solid 8ft swell pushing in from the NW, and the wind goes glassy. That's a magic combo. The water temp is about average for this time of year, which is nice. The combined swell energy is strong (1055). This is the pick of the first week for anyone with the skills.
After that, the surf drops right off. There's a long gap of small, weak, and marginal conditions from Wednesday the 16th all the way through the following week. Swell energy dips well down, and the winds are mostly cross or cross-onshore. It's pretty quiet.
Then, things get interesting again in the second week. Look at Wednesday afternoon, September 23rd. Another solid pulse. The swell bumps up to 8ft from the NW, period stretching out to 12 seconds. That's a proper groundswell, and with glassy conditions, this is going to be a ripper for those who can handle the size. The combined energy is very strong (1831). This is a top-tier call for experienced surfers.
The following Friday afternoon, September 25th, is also worth a mention. It's a bit smaller at 7ft, but the direction is still NW, the period is a solid 11 seconds, and it's dead calm – glassy as a lake. That's another excellent session for the advanced crew.
Overall, the standout windows are the afternoon of September 15th and the afternoons of September 23rd and 25th. Both are for experienced surfers only given the size. The rest of the period is mostly small and messy.
Rusty.
