The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple weeks at Rancho Santini.
Overall, it’s a tough stretch. We’re looking at a lot of days with poor surf conditions and not one standout session that really screams “paddle out.” The forecast period starts now, and the first few days through to the end of the month are mostly a write-off. There’s a real gap of decent surf here – we’re talking over a week of mostly messy, cross-onshore wind and choppy water.
Starting Sunday the 16th and right through the week, we’ve got cross-onshore winds from the northwest, mostly 10 to 15 mph, with swell heights hovering around 2 ft to 3 ft. The swell is coming from the SW and SSW with moderate energy (values around 355 to 564). The period is long, 14 to 16 seconds, which points to groundswell, but with that constant cross-wind and the descriptor “poor surf conditions,” it’s not worth getting excited about. The water temp is sitting at 69° with a 0.9° anomaly – about average for the time of year.
Wednesday the 19th morning shows a brief moment with onshore wind from the west at 9 mph, but it’s still only a 3 ft SW swell with a 16 second period and a “marginal” call. The energy is moderate at 564, but the overall outlook is still poor.
From the 20th to the 22nd, we drop down to tiny 1 ft to 3 ft swell, still mostly cross-onshore, and the energy drops off into the low hundred and two hundred range (162 to 346). Still marginal at best. The morning of the 22nd has a 2 ft SW swell with a very long 18-second period and almost no wind, but that’s a tiny, inconsistent groundswell – fine for a longboard maybe, but hardly a standout.
After that, up until the end of the month, it’s more of the same: 2 ft to 4 ft swell, cross-onshore winds, and “poor surf conditions” stamped on most entries. The energy picks up a bit around the 29th and 30th, hitting 630 and 642, which is now strong wave energy, but it’s paired with those moderate cross breezes and choppy water. The swell on the 27th turns to a short 7-second period from the WNW at 4 ft – that’s weak, wind-driven slop.
Honestly, if you’re a kitesurfer, this stretch of consistent cross-onshore breeze and moderate swell might look interesting. For a paddle surfer, there’s just no clean, quality window here. The setup looks more interesting for kite surfing than paddle surfing.
Stay patient, check back next week, and maybe the forecasts will shift.

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.
