The Lowdown
Alright, folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Straight up, I gotta be honest with you – it's a tough stretch. We're looking at a solid run of poor surf conditions that's gonna last all the way from now until the end of the first week of August. The wind is a problem, plain and simple. That persistent cross-onshore flow from the north and north-northwest is going to keep things choppy and messy. There's nothing really worth paddling out for in that first week and a half, so you might as well save the wax for later.
The only real standout window appears around Saturday, August 8th. On the morning of the 8th, we get a bit of a reprieve. The wind swings to a light onshore from the west-northwest at just 6 mph, which is the cleanest we'll see. The swell is dropping too, but it's still a solid 8 ft from the NNW. That's a lot of juice, but it's borderline – more suited for experienced surfers as it's over 8 ft for the experts. The combined swell energy is strong (791). It's a marginal call, with a little question mark over the tide, but it's the only real chance for a wave. The afternoon of the 8th sees the wind pick up again, so aim for the early session.
After that, it's back to the same old story. The south swells on the 9th and 10th get bigger, with the wind absolutely howling from the north, hitting 31 mph by Monday afternoon. That's blown-out, lumpy, and messy. By the 11th, the swell is holding at 10 ft from the NNW, but with a strong cross-onshore breeze, it's a no-go.
So, the long and short of it is this: we've got a big gap with no real surf until the morning of Saturday, August 8th. That's your one shot, and it's not a sure thing. Keep an eye on the wind and tide, and if you're an experienced surfer, it might be worth a look. The rest of the time, the board stays in the car.
Rusty.
