The Lowdown
Alright folks, Rusty here. Let's get into it.
Alright, looking at the next couple weeks, the opening act is a bit of a mess. There’s a window starting Monday 14 September with some serious size, but it’s a bit out of control.
Monday 14th (Afternoon): That first pulse on Monday gives us 10 ft of NW swell, but it’s raw and short-period at 8 seconds. The combined energy is pumping at 1256 (strong), which is a lot. Honestly, this is just too big for the break. The 15 km/h NW cross-onshore wind won’t help either. A day for watching, not paddling out. The water temperature is sitting around 58°F, which is pretty standard for this time of year.
We go through a run of poor conditions and marginal windows from Tuesday through to Saturday 19 September. A few small pulses, nothing that will get your heart rate up. The one glimmer during this flat spell is Thursday 17th (Afternoon) , where we get glassy conditions with 4 ft of NW swell, energy moderate at 580. It's just not enough size to make it a standout.
Monday 21st (Afternoon): Now we’re talking. This is your real target for the next week. The swell builds back to 8 ft from the NW, period still short at 8 seconds, and energy is cranking at 1455 (very strong). The key here is the glass wind. That's a major positive. This is solid, powerful stuff and it's going to be clean—absolutely perfect for experienced surfers only, as 8 ft is the expert threshold at this spot. This is the standout of the first half of the period.
Tuesday 22nd (Afternoon) to Wednesday 23rd (Afternoon): Slack periods of glassy conditions follow. On Tuesday afternoon, we see 6 ft of NW swell with a 10-second period and energy at 893 (moderate). Wednesday afternoon is similar at 5 ft. Both are clean, but the Monday session is your real winner.
Friday 25th (Afternoon): A bit of a wildcard. The swell drops right down to 3 ft, but it’s a 13-second groundswell from the SSW. Glassy conditions. A fun little lull in the action.
Saturday 27th & Sunday 28th: We get a couple of small, clean days with SSW groundswell, but they’re small.
Monday 28th (Afternoon) & Tuesday 29th: The forecast ends with another significant pulse. On Monday 28 September, we’re looking at 7 ft of WNW swell with a long-period 14 seconds. Energy is a massive 2050 (very strong). This is expert territory again. Then on Tuesday 29 September, it’s back to 10 ft of NW swell, period dropping to 7 seconds, but still very strong energy at 1235. Conditions look okay with cross-onshore winds. This is the long-range promise, but keep an eye on it, it could be a classic if the wind plays ball.
This break is listed as fairly consistent, so it tends to bounce back.
Stay safe out there.

Information about the Chadbourne Gulch Surf forecast
The above surf forecast table for Chadbourne Gulch provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Chadbourne Gulch can be found by selecting the local surf guide option on the grey menu.

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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
