The Lowdown
G’day, Rusty here. Look, I’ve been staring at the charts and the outlook for this stretch of coast isn’t exactly firing. The pattern has got a block on it, and the first week and a half is going to be a real struggle to find anything clean. The good news is there is one small window that actually looks like it might be worth paddling out for. Let’s walk through it.
Right now, through to about August 20th, the wind is mainly cross-on or blowing onshore, and the wave heights are small. We’re seeing swell around 2ft to 3ft from the WSW, with periods between 13 and 16 seconds. The combined energy is moderate, but the quality is poor—it’s mostly described as "poor surf conditions" or "marginal." The surface is going to be choppy and messy. Not worth the effort.
The first real chance of something decent comes on Tuesday morning, August 25th. For a few hours, the wind flips to a south-easterly cross-offshore with light airs, cleaning the surface up. The swell is still small, about 2ft from the SW, but it’s got a long 16-second period, meaning it’ll have real shape and push. The combined energy is moderate (386). This is the standout in the whole run. Rancho Santini is beginner-friendly, and this small clean swell will be perfect for a quiet session. Just remember the spot can get busy, so expect some company.
After that morning, it’s back to the same old story. From Wednesday the 26th through to the 31st, we’re looking at more cross-on or onshore winds and "poor" conditions. The swell stays between 2ft and 3ft with moderate energy, but it’s messy. A spike of energy hits on Saturday, August 29th (607 combined), but with 12 mph cross-on winds, it’s really only interesting for the kite crowd and experts.
So, the bottom line: the first week and a bit is a washout. The only real opportunity for clean, paddle-friendly waves is the morning of Tuesday, August 25th at Rancho Santini. It won’t be overhead, but it’ll be clean and surfable. That’s your best bet. Don’t get your hopes up for the rest.
Rusty.

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.
