The Lowdown

Alright, I'll level with you. This 16-day stretch for Trestles (Uppers) is looking pretty bleak. There's a lot of flat, mushy days to get through before we see anything worth a paddle.

Right now, we're on tiny, weak surf. Friday the 7th of August, the water is a warm 75°F, which is way warmer than usual for this time of year, but that's the only good thing. The swell is a puny 2ft from the SSW with a long period of 19 seconds, but the wind is a light cross-onshore, putting a little texture on it. The combined energy is only moderate (409). The rest of the weekend and into next week is a total washout – poor surf conditions, light onshore winds, and waves barely reaching 3ft. It's flat, it's messy, and it's not worth your time.

Honestly, from the 7th right through to the 21st of August, there's hardly a sniff of a decent wave. The wind is constantly cross-onshore or onshore, and the swell directions are all over the place but never delivering any real power. This is a long, dry spell for a spot that's usually very consistent.

Now, let's look at the very end of the window. The sessions on the 22nd of August – Saturday morning and afternoon – are the only ones that even get a marginal nod. The combined energy picks up a bit (586 in the morning, 526 in the afternoon), hinting at a bit more push. The morning of the 22nd has a light onshore breeze, which is better than the cross-onshore chop. Swell is still small, around 3ft from the SSW with a moderate period of 15 seconds. It's not a standout, it's just the best of a bad lot. But it's still a long way off, so take that as a hopeful whisper, not a sure thing. The crowds at Trestles are always thick, so if this little bump shows, you'll be fighting for waves.

So, the bottom line? The first two weeks are a no-go. The best window is a *maybe* for the 22nd of August, but it's marginal. For a spot that's this reliable, it's a frustrating run. Keep an eye on the charts, but don't get your hopes up.

Rusty.
