The Lowdown
Alright folks, Rusty here. Let’s break down what’s coming.
First thing, the first week is a total mess. We’ve got a nasty combo of strong, lumpy cross-onshore winds and a huge swell that’s way too big for this spot. On August 1st, it’s a 10 ft NW swell with 19 mph winds, and the combined swell energy is hammering in at 1016 – a ton of power, but it’s sloppy and blown out. That poor surf sticks around through the 2nd, with the swell even hitting 13 ft on Sunday afternoon (combined energy of 2387). That’s expert-only territory, and even then, the conditions are just choppy and messy. Beginners, stay home.
We get a tiny glimmer of hope on Monday, August 3rd. The wind swings onshore from the WNW, dropping to a light breeze, and the swell settles to a more manageable 8 ft from the NW. The morning session is the pick of a weak bunch, but it’s still a marginal call with a messy look. After that, it’s back to small, weak, and cross-onshore chop through the rest of the first week. The combined swell energy drops way down, barely cracking 400 at times.
The one true standout in this whole 16-day window is the morning of Monday, August 10th. We get an 12 ft NW groundswell with a solid 10-second period, and combined energy is roaring at 2253. The wind is clean off the land, blowing from the NW at a gentle 9 mph, which should keep things lined up better than the earlier chaos. That said, the swell is huge – over 8 ft – so this is for experienced surfers only, and the rivermouth might get a bit unruly with all that water moving. It’s the best on offer, but don’t expect perfection.
The second week fades out fast. By the 14th, we’re into a very long-period 15-second WNW groundswell, but it’s tiny at just 3 ft, and the cross-onshore wind is back. The energy is there in the period, but not enough height to do anything with it. The spot is already inconsistent, and this stretch is a total blank. It’s a typical quiet spell for this area – a few days of waiting for the next pulse.
All in all, if you’re an expert and can wait until the 10th, you might score a big, windy wave. Otherwise, the forecast is a bust for the near term.
