The Lowdown
Alright, let’s get one thing straight. The next couple of weeks are going to test your patience if you're looking to get wet. The surf is on the small side and more often than not, the wind’s got a bit of cross to it, making things messy. We're looking at a long stretch of onshore and cross-onshore breezes that are going to chop up an already weak pulse of swell. For the first several days, it’s a real battle. You see small, short-period swell in the 1ft to 3ft range, and those winds are just going to wreck it. It’s not going to be worth paddling out for the most part.
We’re looking at a gap here until things start to pick up. For days on end, it’s just not offering anything. You’re going to have to wait for over a week before we see a real change.
The first couple of days of the second week see something of a pulse, but it’s still not great. The swell starts to build a little from the 29th of August, but it’s still small and the conditions are marginal. The wind finally looks like it might go more offshore, but it’s still cross-onshore in the afternoons, which is a pain. We do get a bit more size, with wave heights around 4ft, but it’s still not the clean, lined-up surf we’re after. The energy is moderate, but the quality is still lacking.
The standout in the whole window looks like it’s shaping up for the morning of the 30th of August. That’s when the stars align a little better. The swell is 5ft from the SSW, with a period of 16 seconds. That’s a solid pulse of groundswell. Plus, the wind is blowing from the west, which is dead offshore for Rancho Santini. The water is 69°, which is about normal for this time of year. It’s a morning that will be worth setting the alarm for. It's not huge, but it’ll be clean and have some push to it.
Also worth a look is the morning of the 29th. It’s the beginning of that pulse, with 4ft of SSW swell and a similar 18-second period. The wind is also offshore, so it should be clean. These are the pick of the bunch, but even then, it’s not going to be epic. It’s a case of making the most of the windows of clean surf we get. After that, the swell starts to drop off again as we head into September. So, my advice is to keep your eye on the 29th and 30th, but don't expect perfection. There will be a few fun ones to be had.

Information about the Rancho Santini Surf forecast
The above surf forecast table for Rancho Santini provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rancho Santini can be found by selecting the local surf guide option on the grey menu. Our Rancho Santini surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Rancho Santini) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
