The Lowdown
Right then, let’s have a look at what we’ve got for the only spot on the menu. It’s Rancho Santini, and it’s the full 16 days ahead. The bigger picture is a bit of a mixed bag. We’re looking at a lot of days where the conditions just aren’t going to play ball, with plenty of chop and cross-onshore winds messing things up. There’s some consistent swell energy coming through, but it’s often paired with wind that’s going to make it a messy session.
The water temp here is about average for the time of year, nothing wild to report.
Let’s take it from the top. We start on Thursday the 27th of August, and it’s not a great kick-off. You’ve got a 4ft south swell with an 11-second period, but that cross-on wind from the southwest at 3 mph is just making it bumpy. The combined energy is moderate though, sitting at 553. Friday the 28th is a write-off, with the swell dropping right off to 2ft and straight-on wind. Saturday the 29th gets a bit of a bump in energy (886), but again, that cross-on wind just ruins it. Sunday and Monday are more of the same, marginal at best with the swell hanging around 3ft to 4ft and the wind keeping things messy.
Now, there’s a real standout moment here. Tuesday the 1st of September afternoon – this is where you want to be. The afternoon session is looking glassy. Absolutely glassy. There’s a 4ft south swell with an 11-second period, and the wind has gone completely still. It’s a rare moment of pure glass. The combined energy is 438, so it’s a nice, fun size for a beginner-friendly, consistent wave like this. That’s the window.
Everything after that gets a bit rough again. Wednesday the 2nd of September the wind picks right back up. Thursday the 3rd of September sees a bigger swell jump to 7ft from the SSW with a 13-second period, and the energy rockets up to 2255 – that’s some serious power. But the wind is cross-onshore at 12 mph, and for a beach setup like this, that’s just going to be a washing machine. That kind of size and wind makes it more of a kite-surfing show than a paddle session.
We then go into a long, dry spell. From Friday the 4th of September right through to Tuesday the 8th of September, it’s all poor or marginal calls with messy cross-onshore winds. The swell is there, mostly around 3ft to 4ft, but it’s just not clean.
Finally, the pattern breaks on Tuesday the 8th of September. Another standout, but a week away. The morning session on the 8th is glassy again with a 2ft south-southwest swell. The afternoon is even better – clean, cross-offshore wind from the southeast at 6 mph. That 2ft swell from the southwest has a massive 19-second period, which is very long period groundswell. For a beach break like this, that long period will make it break a bit straight, but if you find a sandbank, the energy and shape could be really fun. It’s a promising session, but it’s a long way out, so stay hopeful.
After that, the last few days of the period from the 9th to the 11th of September fall back into the cross-onshore pattern with the swell hanging around 3ft to 4ft, so nothing to write home about.
So, the clear best bet is Tuesday the 1st of September afternoon for that rare, glassy surf. The second look is Tuesday the 8th of September for clean conditions with that super long period swell.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Rancho Santini may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
