The Lowdown

Alright folks, Rusty here. Let's have a look at what Chadbourne Gulch has in store for us over the next couple of weeks. It's a bit of a mixed bag, so let's get into it.

Right off the bat, things are pretty quiet. We've got a small, 2ft SW groundswell rolling in, with a very long period of 18 seconds. The combined swell energy is weak at 551. The wind's light and cross-onshore, so conditions aren't great. The water temp is about average for this time of year, nothing to write home about. It's a beginner-friendly spot, but for the next few days, you're really just looking at marginal surf. Waves are small and the wind isn't doing us any favors. We've got a stretch from August 24th through to the 27th where it's all pretty poor.

There’s a bit of a pick-up around Friday the 28th morning, with the swell bumping up to 3ft from the SSW, still with a sweet 16-second period. The energy ticks up a notch (641). But it’s still cross-onshore and marginal.

The weekend of the 29th and 30th sees a noticeable increase in size, with chest to head-high SSW swell (4ft) and a long 18-second period. The combined energy jumps to a moderate 1140 early Saturday morning. It’s still cross-onshore, but the swell has some grunt. It's inconsistent though, so be patient.

Now, a real standout. Mark your calendars for Thursday, September 3rd, in the afternoon. The wind is forecast to go glassy, dead calm, and we have an 8ft NW swell hitting the beach. That's a lot of power (1359 energy). This one is for experienced surfers only, because that's big for this spot. The period is short, 8 seconds, but the conditions will be clean and lined up. This is the best of the whole run, no question. The wind will be offshore from the west, making for some proper clean faces.

The energy builds further into the 4th and 5th of September, but the wind gets messy. By Saturday the 5th, we're looking at a huge 12ft NW swell (2781 energy), but with a fresh 22 mph cross-onshore breeze, it will be lumpy and blown out. Not good for a paddle. For a beach break like this, that's more a kite-surfing setup than a surfers' one. The 6th of September stays big (10ft) with lighter winds, and even goes glassy on the Sunday afternoon, but the forecast notes the swell is just too big for this break.

After that big swell fades, we get a clean-up. Monday the 7th afternoon sees a small 2ft SSW swell with glassy conditions and a light offshore breeze. Perfect for a longboard or a fun board. Expect good conditions, but it's a small one.
