The Lowdown

Alright, let's talk about what's coming up for the next couple of weeks. There's one spot that's the main focus, but the conditions are going to be a real mixed bag.

The first thing to say is that we're starting off with a bit of a flat spell. The first few days are looking pretty average, with a lot of "poor" and "marginal" calls. The swell is there, but the wind is just not cooperating. It's going to be a slow start, but there is a little window of hope.

The standout here is definitely Trestles (Uppers). It's a world-class reef and point, almost always breaking, and it faces west, which is just about perfect for this spot. The water temp is about average for the time of year, so you'll be fine in a spring suit.

Looking at the first week, from Sunday the 16th through to Saturday the 22nd, it's a bit of a struggle. The swell is small, around 2 ft to 3 ft, coming from the SSW. The main problem is the wind. We've got a lot of cross-onshore breezes, which is making the surface choppy and messy. The combined energy is moderate, starting at around 534 (moderate) on Sunday morning but dropping off quickly. It's not the clean Trestles we all know and love. There are a few moments on the 18th, 19th, and 20th with light onshore winds, which might clean it up a little, but the scores are still low. It's a good time to be doing something else.

The following week doesn't look much better to be honest. From the 23rd to the 31st, the swell stays small, around 1 ft to 3 ft, mostly from the SW or SSW. The wind remains a persistent issue, often cross-onshore, though there are a few lighter windows. The real highlight, and the only one I'd get excited about, is the afternoon of Wednesday the 26th of August. We've got a glassy, clean forecast with zero wind out of the northwest. The swell is still small at 2 ft from the SW, with a period of 16 seconds—that's a nice long-period groundswell that should wrap around the point beautifully. The combined energy is only 262 (moderate), but the glassy conditions will make it way more fun than the numbers suggest. For that one afternoon, it's the best on offer.

After that, it's back to the same story: small, sloppy, and not worth the paddle out. The 27th through the 31st are all poor to marginal, with cross-onshore winds ruining the surface. The 28th of August has a bit more energy at 3 ft, but the wind is up again.

So, if you're keen, wait for that Wednesday afternoon, the 26th of August. It's the only real window of clean, glassy surf at Trestles. The rest of the time, it's a bit of a write-off for quality waves. Keep an eye on the forecasts, but don't hold your breath.
