The Lowdown

Alright, grab your board and let's talk about what's going on. It’s a bit of a flat spell out there right now, so don't get too worked up just yet. The ocean is gonna need a few days to find its pulse, but there are some interesting signs further down the line. Let’s break it down, day by day.

To start, things are pretty gutless. This Tuesday afternoon, you're looking at a weak 3ft of southwest swell, but the northwest wind is gonna chop it all up. It's messy, lumpy, and not worth your time. The water is at 73°, which is 5° warmer than normal for this time of year—that's a big deal, really pleasant.

The next few days are more of the same. We've got a long-period groundswell trying to show up, with 16-second periods, but the size just isn't there. Wednesday through Friday, we're stuck with small cross-onshore slop. The swell energy is weak, in the 291 to 635 range (moderate at best), and the waves are just too small and bumpy to be any fun. It's a waiting game.

The weekend isn't looking much better, folks. The swell drops further and the winds stay funky. It's looking like a total write-off until at least Monday the 14th. This is a solid stretch of flat, poor conditions, so don't feel bad about finding something else to do.

Then, we see a small pulse of energy trying to move in. From Monday the 15th through the following week, there's a persistent, but tiny, southwest swell in the 1ft to 2ft range. We're also seeing those long periods, 18-20 seconds. This could be a sign of better things to come. The winds are light, which is good, but the size is still way too small to surf. It's a tease, really.

Now, the first really interesting window pops up around Tuesday the 22nd. The swell jumps up to 3ft from the southwest, with a 16-second period, and the wind is looking light. This is when Trestles (Lowers) might start to show its potential. The combined swell energy is still only moderate at 650, but it's the best we've seen. The forecast is for both the morning and afternoon to have some clean conditions.

That week looks like it could be our best shot. The following Wednesday the 23rd still has some swell but the winds pick up a bit and cross the swell, making things a little lumpy again.

So, the standout is going to be around Tuesday the 22nd, maybe Wednesday morning. The wave size is still on the smaller side, but with a clean 3ft south-west swell and light winds, the lines should be holding up nicely. It's not going to be a barn-burner, but it'll be the cleanest, most rideable swell we've had in weeks.

It's a long way out, so don't book the day off just yet, but that's the one to keep an eye on. It's promising, but these long-range forecasts can shift, so we'll keep our fingers crossed.

For the rest of the run, it's mostly small and unexciting. The best bet is to be patient.

Stay stoked.
