The Lowdown
Alright, this is Rusty, and I’ve got the scoop on our local stretch for the next couple of weeks.
Chadbourne Gulch is the only spot showing on the charts. Water temp is 57°F, dead average for now. Don't get too excited.
We're starting off flat and weak. Monday the 31st through Wednesday the 2nd of September sees small, unimpressive swell—maybe 2 to 3 feet—with cross-onshore breezes and combined energy readings that are all in the moderate low range. Not worth paddling out for.
But listen up. Thursday the 3rd of September morning has a standout moment. A clean 3 foot swell from the SSW, with a 19-second period, light cross-offshore wind, and combined energy of 1035. The report flags it as “excellent for experienced surfers.” The direction is close to what this break likes. It’s your best early window for real quality.
The next few days, September 4th through 6th, get messy with onshore winds and deteriorating shape. Stay home.
Monday the 7th of September is a double-header. Clean and small in the morning, but the afternoon turns glassy with a 7 foot NW swell. The report says “very good surf conditions.” That’s a proper session if you can get out there.
Then it gets big. Wednesday the 9th afternoon, a 12 foot NW swell arrives, but the break is called “too big.” Strong wave energy (2253). Thursday the 10th sees more 10 foot glassy surf, again too big for comfort. The energy readings are all in the very strong range. This is expert territory only.
Friday the 11th of September afternoon offers a clean 7 foot NW swell with completely calm wind. The report says “very good surf conditions.” That’s the pick for the second week, but it’s a hopeful long-range signal, not a guarantee.
The final days, September 13th to 15th, keep that NW swell pumping around 7 to 10 feet, but the winds switch cross-onshore and the quality drops. A lot of potential, but a lot of chop to go with it.
To sum it up: target the morning of September 3rd for classic lines, or the glassy windows on September 7th and 11th for fun, clean waves. The rest is either too small, too rough, or far too big for this spot. When that wind blows on the big days, the kite surfers might have more fun than we will.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Chadbourne Gulch may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
