Rancho Santini Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it. We’ve got a mixed bag coming up for Rancho Santini. The first few days show some swell, but the wind is going to be a problem, keeping things messy. The best window is actually in the first week, but it’s a narrow one.

The main event is a solid pulse of long-period groundswell that kicks in on the weekend. Starting Saturday morning, the 5th of September, we’ve got a 4ft swell from the S with a period of 13 seconds, and the combined energy is moderate but punchy at 1009. The wind is light from the W, which is offshore and clean. That’s the best bet early on. By Saturday afternoon, the swell bumps up to 5ft (energy 1238), but the wind swings to a light NW breeze that’s cross-onshore, so it’ll get a bit of a ripple on it.

Sunday the 6th sees the biggest swell of the period, with 7ft from the SSW and a 13-second period, and energy jumping to 1744. That’s a lot of water moving. But the wind is a dealbreaker – NNW at 9-12 mph, blowing cross-shore and creating a cross-chop. For a beach break, that’s not going to be pretty. This setup is more interesting for kite surfing than paddle surfing. It’s still fair-sized, but it’s going to be a mess.

The water temperature is about average for this time of year, nothing to write home about.

From Monday the 7th onward, the swell drops and the wind stays onshore or cross-onshore, with speeds from 9-16 mph. The energy drops from 1557 down to under 300 by the middle of the second week. The 9th of September sees the swell drop to 4ft, then down to 2ft, and the wind is cross-onshore, making it mostly poor. There’s a real gap from around the 10th onwards, with surf dropping to 2ft or 2ft, and the wind staying cross-onshore almost every day. The end of the forecast, from the 17th to the 19th, shows a tiny 1ft to 2ft swell with a very long period (18-21 seconds), which might look better on paper, but at that size, it’s not going to break with any power at a beach break. The wind is still cross-onshore.

So, the standout is pretty clear. Saturday morning, the 5th of September, is the pick of the lot. Head to Rancho Santini for a 4ft, S swell with a decent 13-second period and clean offshore winds from the W. It’s consistent, and while crowds are sometimes a thing, the quality will be worth it. The rest of the week is a washout or a kite session.

Rusty out.
