The Lowdown

Alright folks, let’s get into it. The short version? The next couple of weeks are going to test your patience. There’s surf on the horizon, but it’s going to take a while to show up, and even then, it’s not going to be a classic. We’re looking at a real slow burn here, so let’s break it down.

The first real window we have to talk about is the morning of Friday, August 7th. Up until then, it’s just tiny, weak leftovers, nothing worth paddling out for. That Friday morning, Trestles (Uppers) sees a pulse of energy come through. We’re talking about a modest 2ft swell from the SSW, but the period is a solid 19 seconds. That long-period groundswell will give the waves some push, but it’s still small. The energy is moderate at 410, and the light morning breeze should keep it clean. It’s a marginal call, so don’t expect much. This is the first time you might want to even think about getting wet.

The weekend after that doesn’t get much better. Saturday morning, August 8th, has a bit more size, 3ft, and a 17-second period, but the wind is a bit more on it, so it’s not going to be as clean. Energy is up to 427, but it’s still not great.

We’ve got a stretch here with a few days of nothing. The swell stays small, around 2ft to 2ft, with shorter periods. It’s not really a surf, more like a bump. You can almost write off the next four or five days. The water is warm, 76°, which is about 9° warmer than the long-term average. That’s a big deal, incredibly warm for this time of year.

Then, things start to get slightly more interesting as we move into the second week. The morning of Thursday, August 14th, we get another pulse. The swell is 3ft from the SSW, with a 19-second period. The energy jumps to 590, which is still moderate, but it’s got some push. It’s a marginal forecast, but the potential is starting to build. The next day, Friday, August 15th, is where it starts to look like the best bet of the whole stretch. The morning sees the swell bump up to 4ft from the SSW with a 16-second period, and the energy climbs to 744, which is getting close to that strong range. The wind is light and cross-onshore, so it might be a little lumpy, but there should be some proper waves at Trestles (Uppers). This is the day to circle in the calendar.

The weekend after that, August 16th and 17th, holds some size, around 3ft to 3ft, but the west winds start to pick up and come more cross-onshore, making conditions choppier and less clean. It’s surfable, but not a standout. The energy remains moderate, in the 300 to 400 range.

So, the long-range call is for that Friday, August 15th. It’s not going to be huge, but it’s the biggest, most consistent swell of the window with the best energy. The wind won’t be perfect, but it’s the most promising day. The water is going to be warm and the crowds are always a factor at Uppers, so be ready for that. For the rest of the time, there are plenty of days where the waves will be rideable on a longboard, but nothing to write home about. The forecast can change, but right now, this is what we’ve got. This is a period for the patient ones.
