The Lowdown

Alright, let’s get straight into it. I’m not gonna sugarcoat this one, folks. The next stretch is looking pretty flat and funky for Third Peak.

We’ve got a bit of a rough start with some weak, short-period easterly windswell pushing in. Wednesday afternoon kicks things off with a meager 1 ft of east swell at a shaky 7 seconds. The wind’s light out of the east, but it’s cross-onshore, so the surface is gonna have that bumpy, rippled look to it. The water’s running a touch cooler than usual for this time of year, about 3° colder, so you might want a slightly thicker suit if you’re paddling out.

Honestly, the first few days are a write-off. Thursday and Friday see a little more size—maybe getting up to 3 ft and then 4 ft by Friday afternoon—but the period stays short and the wind stays messy. That Friday afternoon bump will bring the most energy we see for a while, but it’s still just short-period wind chop. It’s going to be lumpy, and the easterly breeze is going to put a crinkle on everything.

The weekend doesn’t offer much redemption either. Saturday has some chest-high waves, around 4 ft, but the period is still stuck at 8 seconds. It’s a beach/jetty setup, and with that short-period, crumbly swell, it’s going to be a bit of a closeout fest. The wind is cross-shore, so it won't be totally blown-out, but it's not going to be clean. Sunday drops back down to ankle-biters, and from there it’s a long, slow slide into tiny.

We get glimpses of more organized energy late in the second week, with the period stretching out to 9 seconds by the 18th and 20th, but the swell height is tiny. Wednesday the 13th has some glassy conditions in the early morning with a 0.7 ft swell. That’s barely a ripple. Skip it.

Here’s the long and short of it: the best conditions are going to occur on the clean mornings, even though the surf is tiny. These will be the glassy or light offshore moments where the ocean looks like a lake and you might catch a knee-to-thigh-high slapper on a longboard. The 12th, 13th, and 16th-19th all have these glassy or cross-off moments early. It won't be pumping, but if you're desperate for a paddle and a smooth surface, that's your window.

Otherwise, it's a lot of closeouts and chop. The swell direction holds from the east, which isn't ideal for this spot, and the consistent onshore flow will keep it lumpy.

All this weak, short-period swell with those constant easterly winds, this looks more like a day for the kiteboarders to get their jollies than for us surfers. There’s just no push or form to any of it.

If you absolutely need to get wet, pick a morning with the light offshore wind and just get a few fun little ones. It’s not going to be memorable, but it beats working. Keep your expectations low and you won't be disappointed.

Rusty, out.
