Alright, let's look at what's cooking for the next couple of weeks.

Honestly, I gotta say, it's a slow slog for Trestles (Uppers) right now. We’re looking at a long stretch of pretty average conditions, mostly from a cross-onshore direction and short-period swell. The water's sitting at 68° with a water temperature anomaly of 0.9°, so it’s about average for this time of year in the water.

For Saturday the 11th, the swell's coming in from the SSW at about 3ft with a 15-second period. That long period is nice, but the problem is it's wrapped around the point-of-view. The waves are there—combined energy is moderate at 471—but the wind is a cross-onshore breeze from the south at 15 km/h, making it choppy. You might get a few, but it won't be pretty. The morning is a little more promising for the very advanced surfer, but it's a struggle.

Sunday the 12th through to Tuesday the 14th of July is flat or close to it. Short-period swells and onshore winds mean we’re looking at tiny, weak lines. Combined energy drops right off to 185 on Tuesday, so really not worth paddling out.

Wednesday the 15th is more of the same, with swell dropping to just 1ft. The wind is from the SW at 10 km/h, but even with light onshore winds, the wave state is unknown, which usually means it’s junky.

We start to see a pulse building on Thursday the 16th with a bump in size up to 4ft, but that 8-second period is ridiculously short. It's just windswell—bumpy and gutless. Combined energy jumps to 271, but it's poor quality still.

The first real glimmer comes up on Saturday the 19th of July. We get a pulse of south swell at 4ft with a 12-second period, and combined energy hits a strong 848. The wind is a light, glassy onshore from the WSW at 10 km/h in the morning. This is the best-looking window of the whole run. The wave state is marginal, but with that energy and clean morning conditions, this is the standout period for the next week. Keep in mind that long-period groundswell can be a bit walled at a point break like this, but it should offer some good lines.

After that, the following week is messy. The wind is mostly cross-onshore, and we see a lot of moderate energy around 500-600 in combined energy, but the surface is choppy. From Monday the 20th to Wednesday the 22nd, you’re fighting a moderate breeze up to 21 km/h, so the ripples will be frustrating.

The end of the window looks slightly more interesting. On Saturday the 25th, we get a long-period SSW groundswell with a 21-second period—very long. But it’s only 2ft, so you’re looking for those rare, clean sets. Combined energy is again strong at 440, but the size is tiny. By Sunday the 26th, the swell bumps up slightly to 3ft from the SSW with an 18-second period and combined energy of 837, and the wind is off the land from the SW at 5-10 km/h. This might be the best for a dedicated surfer, but it’s over a week away and long-range forecasts can change.

Crowds are always a factor at Trestles, but for this run, it's likely to be quiet because the conditions are generally poor.

Overall, the standout is the morning of Saturday, July 19th with the 4ft south swell and that light glassy wind. After that, keep an eye on Sunday, July 26th for a promising but less certain session.
