The Lowdown
Alright, let’s break it down for the imperial crew. Rancho Santini is a beginner-friendly spot, consistent, and gets its best juice from W swells. The water temp is about 70°, pretty normal for August—nothing wild goin’ on there.
From Saturday 15 August through Monday 24 August, it’s a whole lot of nothin’. Swell’s barely 3ft, with a long period from the SW, but the wind is blowin’ cross-onshore at 12 km/h or more, makin’ everything choppy and ugly. Energy numbers are hangin’ in the moderate range (356 to 688), but it’s honestly just poor surf. You’re better off takin’ a nap.
Then Tuesday 25 August rolls in like a different spot. Swell bumps up to 6ft from the S, with a 16-second period, and the energy jumps to 1948—strong stuff. The wind is light and cross-onshore, so the waves will be a bit lumpy but way cleaner than what we’ve seen. It’s still marginal, but this is your clear standout day. Wednesday 26 and Thursday 27 hold that 6ft swell, periods around 13–14 seconds, and energy still over 1200. Winds stay light, mostly cross-onshore. That swell size is over 5ft, so it’s not for total newbies, but for anyone with a bit of time in the water, it’s gonna be fun.
After Thursday 27 August, it drops back to under 3ft and the energy fades. By Friday 28, it’s back to poor conditions and small waves. So bottom line: aim for Tuesday 25 through Thursday 27 August. That’s where it’s at. Everything else is a flat spell.

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.
