The Lowdown

Alright, this is Rusty, and I’m looking at the outlook for Chadbourne Gulch. Water temps are sitting right around where they should be for this time of year – nothing wild there, just what you’d expect.

Right off the bat, we’ve got a bit of a slow start. The first few days are pretty marginal. Wednesday morning the 26th has a bit of small 2ft SW groundswell rolling in with a 16-second period, but the wind is cross-on from the WNW at 6 mph, and the combined energy is only 371—pretty weak. The afternoon and Thursday don’t look much better, with poor surf conditions and the same light cross-onshore breeze messing things up.

Friday the 28th shows a little more pulse. The morning brings 3ft SSW swell, but conditions are still marginal. The afternoon sees a jump to 6ft, but it’s a short-period NW windswell at 7 seconds, and the combined energy climbs to 867. Still, with that short period and cross-on wind, it’s not going to be pretty.

Saturday the 29th morning has the best-looking swell so far: 4ft of SSW groundswell with a very long 18-second period, and combined energy of 1412. That’s a groundswell with some serious push. The problem is the wind stays cross-on from the WNW at 6 mph. That long period means the sets will be clean and powerful, but the cross-on breeze will put a bit of texture on the face. The afternoon sees the swell drop a touch and the wind picks up to a gentle breeze, making it choppier.

Sunday the 30th morning is the first real standout. The wind shifts to onshore from the WNW, but it’s still just a light breeze at 6 mph. The swell is 4ft from the SSW with a 16-second period, and the combined energy hits 1068. This is moderate energy, and with the wind being on, the waves should be clean and lined up. The long period means it’ll be better suited for a point or reef setup, but it should still offer some fun corners at this beach. This is the best session on offer in this outlook.

The rest of the week into early September is a bit of a mixed bag. Monday the 31st has a smaller 3ft swell with onshore winds in the morning, but the energy drops to 591. It’s marginal. Tuesday the 1st of September is even smaller, with 2ft and poor conditions in the afternoon. The run from the 2nd to the 4th is a bit of a tease. Wednesday the 2nd has a 4ft NW windswell, but the period is only 9 seconds, and the energy is 495. Thursday the 3rd morning brings a 2ft SW groundswell with a very long 19-second period, and energy of 1001, but it’s still marginal. Friday the 4th morning has the biggest swell of the whole period: 7ft from the NW with a 10-second period and combined energy of 1705. That’s strong energy, but it’s a short-period windswell at 7ft, which is getting into expert-only territory, and the wind is onshore. The afternoon drops to 6ft.

After the 5th, the surf fades back to small and marginal for the rest of the second week, with SSW swells around 2ft to 4ft, and combined energy mostly under 1000. There’s a last little pulse on the 8th of September with a 2ft SSW groundswell and a very long 20-second period, but it’s marginal. Overall, the standout is Sunday the 30th morning, with a decent 4ft swell, clean conditions, and enough energy to make it fun.

Rusty.
