The Lowdown
Yo, Rusty here. Let’s break down this 16-day stretch for Rancho Santini. Honestly, it’s a grim outlook. We’ve got a long patch of poor to marginal conditions across the whole window, so don't get your hopes up. The swell is around, but the wind is just constantly ruining it. There are no true standouts here, not a single day I’d be keen to paddle out for.
From Monday the 17th through the 24th of August, it’s a write-off. Swell hangs in the 1ft to 3ft range from the SW with long periods of 14 to 18 seconds – that’s proper groundswell in theory – but the wind is cross-onshore from the NW and WNW most of the time, making it choppy and poor. The combined energy is moderate, hitting up to 447 on Tuesday, but it’s not working for you. Even when it goes offshore on the 19th afternoon, the quality stays poor. There’s a slight glimmer on the 20th and 21st with the wind easing to a light breeze and scores creeping to a 1, but it’s still only marginal – light cross-onshore ripple and small waves around 2ft to 3ft.
A gap here: from the 24th afternoon, it’s poor to marginal right through to the end of the month. You get a slight uptick on the 29th of August – combined energy jumps to 628 (strong) with a 3ft SW swell and a light breeze, but the cross-onshore wind is still there, so it’s only a 2 out of 10. That’s as good as it gets, and it’s not good. The 30th offers a 3ft swell with a cross-shore wind, which is a bit cleaner, but still marginal.
The last couple days into September stay poor with that cross-onshore wind. Overall, the whole 16-day window is a battle for a clean wave. Stick the longboard away, grab a kite, or just find a different hobby for a bit. It’s a dry 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.
