The Lowdown

Alright, this is Rusty. Let’s talk about what’s on the menu for the next couple of weeks.

Overall, it’s a pretty quiet stretch ahead. We’ve got tiny, onshore-battered swell for the majority of the period. The water is sitting at a very warm 76° – that’s much warmer than usual for this time of year, so you’ll be in boardies for sure.

Right now, and for the first week, the surf is pretty much flat. From Monday the 3rd of August right through to Sunday the 9th of August, we’re looking at tiny waves, mostly 1ft to 2ft, and coming straight onshore from the SW or SSW. The wind is light, but it’s all onshore, so the wave faces are just messy. Monday morning saw a 2ft SW swell with a long period of 13 seconds, but the cross-on wind made it choppy and ugly. Combined energy was weak to moderate (119), but it just didn’t get a chance to clean up. The only faint glimmer pops up on Saturday afternoon, the 8th of August, where the score edges up to a 1, but it’s only a 3ft SSW swell, still onshore, and it’s described as marginal. You’d be hard-pressed to find a wave worth paddling out for.

The second week doesn’t look much better, but there’s one day that stands out as the best on offer. Monday the 17th of August, in the afternoon, we get a break in the pattern. A light NNW breeze, blowing cross-offshore, finally cleans up the surface. The swell is still a modest 2ft from the SSW, with a period of 15 seconds, but that cross-off wind is a game-changer. The combined energy is moderate (353), and the comment says "expect good surf conditions". This is the one session to circle. It won’t be big, but it’ll be the most fun you’ll have all week. Tuesday the 18th of August sees the swell try to pick up a bit, but the wind switches back to a cross-on from the W, and the period drops to a short 8 seconds, ruining any shape.

So, the summary is rough. A long gap of poor surf, then one promising afternoon on the 17th. If you can wait, that’s your window. Otherwise, it’s a slow time for Trestles (Lowers).

Rusty.
