The Lowdown
Alright, let me tell ya, it’s a tough stretch for Santa Clara Rivermouth. The whole 16-day window is looking pretty grim, I gotta be straight with you. There are no good surf options to get excited about right now. The swell is tiny and weak, and the wind is almost always on it or cross-onshore, just messing up what little bump there is.
From Thursday the 6th of August right through to the end, it’s the same story. We’re looking at swell heights from 0.7 ft to a maximum of 2 ft, coming mostly from the SSW. The wave energy is weak, staying under 100 for most of the first week, only climbing into the moderate range of 100-299 (like 119 on the 7th morning, 145 on the 8th morning, 199 on the 14th morning, and 299 on the 14th afternoon). Even with a little more energy, the quality is still rated as poor. The period is mostly long, between 14 and 19 seconds, which is groundswell character, but there’s just not enough size to do anything with it. The long period might make the sets a bit more defined, but it’s still a struggle.
The only real standout in the whole forecast is possibly the afternoon of Thursday the 20th of August. Swell bumps up to 5 ft, but it’s coming from the west with a short, weak period of only 6 seconds. That’s windswell, not groundswell. The water temp is about normal for the time of year, so at least that’s not a shock.
Honestly, the setup looks more interesting for a kite surfer than a paddle surfer, especially when the wind picks up to moderate or fresh cross-onshore. For a beginner-friendly spot that’s very consistent, this is a real bummer. It’s one of those blank runs that happens. The forecasts can change, but for now, don’t bother waxing up.
