The Lowdown
Alright folks, Rusty here. Let’s break down what Chadbourne Gulch has in store for the next couple of weeks. Don’t rush out the door just yet – it starts slow.
The first few days are building up energy but the waves are pretty average. Thursday morning 27 August kicks off with tiny 2ft swell out of the SW, combined energy 302. Winds are cross-onshore from the WNW at 6 mph, making it a bit bumpy. Nothing to get excited about. Friday morning 28 August bumps up to 3ft SSW swell combined energy 599, but the wind is still onshore. Still marginal.
By Saturday 29 August we see 4ft SSW swell early with combined energy 1119, but winds pick up to 9 mph from the WNW and it gets lumpy. Afternoon clears up but wind picks to 12 mph, choppy. Not our day. Sunday 30 August morning might be the best of this first stretch: 4ft SSW swell, 16-second period, light onshore wind, combined energy 1078. That long period groundswell will have some grunt, but with a beach break expect it to stand up quick.
Then we hit a flat spot. From Monday 31 August through Wednesday 2 September, waves drop to around 2ft to 2ft, combined energy dropping as low as 288. Thursday 3 September sees a 2ft SW swell with a 19-second period, combined energy 1124 by afternoon – powerful but super long-period, tricky for this spot.
A clear standout shows up Monday 7 September afternoon: 7ft NW swell, glassy conditions with wind from the SW at 3 mph. Combined energy 801, and the report says “expect very good surf conditions.” That’s the session to plan for. It’s got size, so if you’re a beginner, maybe give it a miss. For the rest, it’s clean.
Tuesday 8 September afternoon is also nice: 5ft NW swell, cross-off wind from the SE at 3 mph, clean. Combined energy 658.
Looking further out, Thursday 10 September afternoon brings 6ft NW swell at 11 seconds, combined energy 1277 – decent. Then Friday 11 September afternoon hits a big 11ft NW swell with a short 8-second period, combined energy 1932 – way too much for here. Winds are cross-onshore, so that’s a hard pass for paddling. Might be kiting territory.
Your best bet: Monday 7 September afternoon, glassy, clean, manageable size. Tuesday 8 September afternoon is a close second.
Rusty.
