Trestles (Lowers) Surf Forecast and Surf Report

Alright folks, Rusty here with a look at what’s coming up. We’ve got a 16-day window, but honestly, for the first week and a half, it’s gonna feel like we’re sitting on our hands. There’s a big stretch of nothing special to write home about.

We’ve got Trestles (Lowers) as our only real option to look at. The water’s sitting at a warm 72°, which is *way* warmer than usual for this time of year—we're talking much warmer than normal. That’s a nice bonus when you’re sitting out there.

Starting Tuesday afternoon, August 18th, the swell is tiny at 2ft from the SSW, but it’s got some real grunt with a 17-second period. That's a proper long-period groundswell. The problem? Cross-onshore wind and a combined energy reading of 382, which is moderate—but the overall vibe is just "poor surf conditions." Not worth paddling out for.

Wednesday the 19th into the weekend is a tough stretch. Swell hangs around 2ft to 3ft, period stays long (13–19 seconds), but the wind is all wrong. It’s mainly onshore or light cross-on, and the combined energy dips into the low hundreds. We’re looking at marginal surf at best. There’s a lot of “questionable tide conditions” chatter in the data.

The real kicker is the gap. From Tuesday the 18th all the way to the end of August, there are no legitimate standouts. The surf just isn't happening. It's a dry run.

Now, if you’re willing to wait, things start looking interesting towards the end of the month. Saturday, August 29th, we finally get a pulse. The morning shows a 4ft SSW groundswell with a 17-second period, combined energy jumping to 792 (moderate to strong), and light cross-onshore wind. The afternoon is similar: 4ft at 16 seconds. This is the best on offer, but it’s still only scoring as marginal. It’s a promise, not a guarantee. The wind isn’t perfect, but it’s light enough that Trestles might get some shape out of that long-period energy. Keep an eye on it.

Sunday the 30th and Monday the 31st keep some of that 4ft to 3ft SSW swell, but the period drops a bit, and the wind turns more onshore. The combined energy drops back into the 400s. It’s fishable, but not epic.

Into the first week of September, the swell fades again. Tuesday September 1st has a tiny 1ft wave with a super long 18-second period (combined energy 395) but with onshore wind. Not your day.

The second week is touch and go. Wednesday the 2nd has some bump in energy (592) with 2ft SSW swell, but again, the wind is cross-on. Nothing is screaming “drop everything and go.”

If you’re a kiter, the consistent wind and small, choppy surf on those beach-and-reef days might be more your thing than paddle surfing.

So, the takeaway? A long quiet spell, then a flicker of hope around August 29th. Don’t get your hopes up too high, but it’s something to watch. Forecasts can change.

Rusty.
