The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on offer for the stretch ahead.
Straight up, don’t get your hopes up too high. This is a long run of small, onshore-affected days for San Clemente State Park. The first solid look we get isn’t until the end of the first week, and even then, it’s marginal. The combined energy (676) on Friday afternoon, August 14th, is the highest of the whole run, but the wind is a cross-onshore breeze and the surf is still small. The swell direction is SSW, which is fine for this exposed spot, but the period is a long 18 seconds, so it’ll be better formed but with longer lulls between sets.
The best chance for something cleaner comes on Saturday morning, August 15th. The swell picks up to 3 ft from the SSW, with a 16-second period, and the wind is only a light cross-onshore breeze. The combined energy (648) is solid. It’s not going to be world-class, but it’s the most likely window for a longboard or a fun log. The water temp is about average for the time of year.
After that, the pattern stays grotty. A mix of onshore and cross-onshore winds, tiny swell under 3 ft, and the energy drops off. There’s a bit of a pickup around August 23rd and 24th, with swells from the SW and periods around 18–19 seconds, but the heights are still 2 ft – 2 ft, and the wind is usually onshore or light cross-onshore. It’s frustrating, but it’s consistent in that it’s consistently small.
The standout: Saturday morning, August 15th. That’s your best bet. It’s still small at 3 ft, but the light wind and decent energy make it the most surfable session of the whole 16 days. If you’ve got a longboard, that’s the time to go.
Rusty.
