Rancho Santini Surf Forecast and Surf Report

Alright, this is Rusty, and I’m looking at the forecast for our little corner of the world. Let’s be real: the next couple of weeks are a bit of a slow burn, but there’s a window or two worth paddling out for.

Straight up, the first day we’ve got any surf on offer is Tuesday, August 25th, and it’s a mixed bag. The water is sitting at 70°, which is pretty much bang on average for the time of year, so no surprises there.

The run from Tuesday the 25th right through to early September is mostly a waiting game. We’re looking at a lot of days with marginal, poor, or just plain flat conditions. The swell is small, running between 2ft and 4ft, and while the periods are solid (swell energy is moderate, in the 400-700 range), the wind is often a bit messy – cross-onshore or just not clean enough to make it worth your while. The standout in this early stretch is Wednesday, August 26th. The morning shows a 5ft swell from the south with a 12-second period, and the wind is light cross-shore from the SSW. That’s not glassy, but it’s far from blown out. The combined energy is a solid 813, which is the most we’ll see for a while, and it’s the biggest swell of the week. Rancho Santini is a consistent, exposed beginner spot, so the crowds might be around, but the conditions are just promising enough for a fun, manageable session.

After that, it gets pretty grim. From Friday the 28th right through to the start of September, the forecasts are all poor or marginal. The wind strengthens, gets choppy, and the swell drops. There’s a gap of nearly a week here where I wouldn’t bother.

Now, if you’re looking further ahead, things get a little more interesting for the patient surfer. Come Thursday, September 4th, we start to see a better pattern. The swell picks up to a consistent 4ft-4ft from the southwest, with a long 16-17 second period. The combined energy is back up in the 700-800 range, which is moderate but promising. The wind is offshore and light, which is a huge positive. The wind state is ‘on’ for the mornings, meaning clean, glassy conditions. The best of this run looks like Friday, September 4th morning: 4ft of SW swell, 17 seconds, and a light offshore wind. That’s a classic combo for a long, clean session at Rancho Santini.

The real highlight, though, is looking at Saturday, September 6th and then into the following week. It’s a long-range call, so take it with a grain of salt, but the models are hinting at a run of solid, clean conditions. The swell stays around 3ft to 4ft from the SSW, with periods between 15 and 18 seconds. The wind remains light and offshore for the mornings. If that holds, we’ll have clean lines and consistent waves. The best on offer is likely the morning of Wednesday, September 9th: a 3ft SW swell at 18 seconds, with a light cross-onshore breeze, but the energy is a solid 730. It’s not the biggest, but the quality and consistency could be there.

Don’t get too excited about the big numbers – the swell never gets above 5ft, so it’s fine for intermediates and beginners. The long period (over 15 seconds) means the waves will have plenty of push and shape, but at a beach break like Rancho Santini, they might break a little straight. It’s still better than the flat spells we’ve been dealing with.

So, to sum it up: the pick of the litter is Wednesday, August 26th morning for the biggest swell, and Friday, September 4th morning for the cleanest conditions. The long-range potential for the first week of September is worth keeping an eye on, but it’s not a lock. For now, keep your board waxed and your ears open.

Rusty.
