The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming down the line for our stretch of coast.
Right off the bat, the next week and a half is looking pretty grim. We've got a window of small, weak, and messy swell that's just not going to deliver. The water is a warm 74°F which is much warmer than usual for this time of year, a real anomaly (6°F above normal), but that's about the only upside. The first real chance of anything decent doesn't show up until the very end of the run.
From Friday the 28th of August through to the 10th of September, it's a wasteland. The combined swell energy is mostly in the moderate range, topping out around 1010 on the morning of Thursday the 3rd, but the wind is almost always cross-onshore or onshore, and the wave heights are puny, between 2ft and 5ft. The swell periods are a mixed bag, but the quality is just not there. Trestles (Uppers) is a reef and point break that's very consistent, and it's exposed to the west, which is the optimum direction, but the forecast is just a series of "marginal" or "poor" conditions. Even the bigger swells early in the month are blown out by the wind. For a spot that's usually a sure thing, this is a tough stretch.
Now, hold on to your board, because things look like they might finally turn around on Friday the 11th of September. The morning session is the standout. We're looking at a 3ft SSW swell, but the real kicker is the wind: glassy. An ESE breeze at just 3 mph. That's a major positive. The period is a solid 16 seconds, which is a long-period groundswell. This is the kind of energy that will wrap into the point, giving us some clean, lined-up waves. The combined energy is 386, which is still on the moderate side, but those conditions should make the most of it. Just keep in mind this is a long-range call, so it's promising but less certain. The surf is small, but it could be some of the best quality we've seen in a while.
So, to sum it up: the first 13 days or so are a write-off. The only real standout, the one to circle on your calendar, is the morning of Friday the 11th of September. It's not going to be big, but it could be clean and fun.
Stay patient, and don't paddle out into the chop.
Rusty.
