The Lowdown
Alright, this is Rusty, and I’m looking sixteen days into the window for Slip Point. To be straight with you, it’s a tough stretch ahead. We’re looking at a long, thin run of surf. There are no real standouts in this forecast; the waves are just too small and inconsistent for much of anything, and the wind is often working against us. It looks like a blank run for weeks at a stretch, which is more normal for this area when the conditions don't line up.
Let’s start with what little we have. On Sunday morning, August 9, there’s a tiny 2ft swell from the west, with a short period of 6 seconds and weak energy at 35. The wind is light from the NW, but it’s basically onshore. It’s surfable, but it’s going to be poor. That small window fades into Monday, August 10, with the same weak 2ft westerly swell and short period. By afternoon, the wind goes cross-onshore and it gets choppy, and the combined energy drops to just 21. Honestly, it’s more of a paddle than a surf.
After that, the forecast dries up completely. From Tuesday, August 11 through to Friday, August 22, there are long gaps – day after day with no wave height listed and zero combined energy. It just goes quiet. The wind flips around, we get some glassy calm mornings, but there’s no swell to ride. One morning on Thursday, August 13, the wind is cross-off and clean, but with no wave height, it’s just flat.
It isn’t until Saturday, August 23, that we see a tiny flicker of life again. Early that morning, it’s glassy with a 2ft west swell, period up to 8 seconds, and energy at 61. That’s the best we’re going to see, and it’s marginal. The westerly swell direction matches the optimum WNW for the point, so it has a chance to bend in, but it’s really small, and it quickly goes cross-onshore again in the afternoon.
All in all, there isn’t a standout session. For this 16-day window, don’t expect much. The spot is fairly exposed to west-northwest swell, but the energy just isn’t there. Keep an eye on it, but I wouldn’t be making any plans. This is one of those stretches where forecasts can change, so don’t write off the whole month, but for now, it’s flat and frustrating.
Rusty.
