The Lowdown
Alright folks, Rusty here. Gotta be straight with you – we’re looking at a pretty grim run of surf for the next sixteen days. The numbers just aren't there. We've got a solid two-week stretch where the ocean is basically flat and uninspiring. The only spot on the radar is Trestles (Uppers) , a reef and point set-up that's exposed to the west and handles that direction best. But even there, it's a tough watch.
The water is sitting at 75° and that's a massive 8° warmer than usual for this time of year – feels like a bath out there, but it doesn't help the waves.
For the first week, from the 1st of August through to the 8th, it's a write-off. Swell heights are barely a ripple, mostly 1ft to 3ft, and the combined energy is weak, just scraping into the low hundreds at best (245 to 438). The period is decent, sometimes long (13 to 19 seconds), which usually means good groundswell, but there's just no height to back it up. The wind is light, mostly onshore or cross-onshore from the SW or SSW, so it's clean but completely flat. The main comment is "poor surf conditions" – and that's it. Don't bother paddling out.
The second week, from the 9th of August onwards, doesn't get much better. The swell heights finally tick up a little, hitting 3ft to 3ft, and the energy climbs into the moderate range, peaking around 650 on the 14th. That's from a SSW direction with a very long period (18 seconds). That kind of period can be tricky at beach breaks, but for a point like Trestles, it can wrap in nicely. The problem is the wind stays light but onshore, and the forecast is still tagged as "marginal" or "poor." The crowd factor is also a reality here – this break is "always" crowded, so even if the waves are rideable, you'll be sharing them with a lot of folks.
The best chance you'll get in this whole window is the morning of the 14th of August. It's not a standout by any stretch, but it's the strongest signal. You'll see a short period of 3ft swell from the SSW, with a very long period of 18 seconds and moderate energy (650). The wind is a light cross-onshore, which is okay, but not the clean offshore we'd want. It's the only time the conditions are even labelled "marginal" rather than "poor." For a long-range look, the morning of the 15th of August is also in the same marginal boat, with 3ft from the SSW and light winds, but it's still a gamble.
Look, it's a blank run. There's just nothing to get excited about for a solid paddle. If you're a beginner, anything over 5ft is too much, but we're not even close to that. The swell is too small and the quality is too low. For a spot like this that's usually "very consistent," it's a real bummer. The setup is more interesting for a kite session than a surfboard right now. Keep the board in the car and check back – forecasts can change.
