The Lowdown
Alright, this is Rusty, and I'm looking at the forecast for the Inlet. Gotta be straight with you – it's a tough run.
The next two weeks are looking pretty flat out here. The best we see is a little bump of energy on Wednesday the 22nd, but it's not much to write home about. We're looking at a long stretch of small, weak surf with very few windows of clean conditions. The swell is mostly coming from the SSE, which is not the ideal direction for this spot.
The standout, if you can call it that, is a brief moment on the afternoon of Wednesday the 22nd. The swell from the SSE picks up to 3 ft, with a period of 8 seconds, and the combined energy hits a modest 109. That's still weak, but it's the most energy we see all week. The wind goes light and cross-off, which will clean things up for a few hours. It's a far cry from good, but it's the only surfable window of the whole period for a surfer who's really desperate.
After that, it's back to the doldrums. The rest of the week and into the next is a mix of tiny swell and onshore wind, with nothing breaking the 2 ft mark. A few days, like the 28th, have a glassy morning, but with a 0.7 ft swell, you're just floating. The water is a touch warmer than normal for this time of year, sitting around 76°.
Honestly, for the next 16 days, this is a blank run. It's not a spot that pumps often, and when it does, it's small. The forecast can change, but right now, you're better off checking the cams or doing something else. No standout sessions here, I'm afraid.
Rusty.
