The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for Caballos. It’s a reef break that’s got the right idea, but honestly, for the next few weeks, it’s gonna be a bit of a waiting game. This spot is inconsistent, and while it’s exposed and likes a northerly swell, the charts are showing a whole lot of small, choppy leftovers with wind that’s mostly cross-off, which doesn’t help the shape much. There’s no real standout surfing to rush out for in this window, but there’s one period that might just stir the blood a little if you’re patient.
Right off the bat, from September 5th through the 8th, we’ve got tiny, weak surf – heights around 1 ft to 2 ft, mostly from the east with short periods of 7 to 8 seconds. Combined swell energy is low, bouncing between 55 and 105 (100 to 105 on the higher side), but the wave comment is ‘poor’ through and through. It’s clean, but it’s gutless. Not worth paddling out for unless you just want a float.
Things start to perk up a bit around September 9th and 10th. On the 9th, we see the swell bumping up to 4 ft to 5 ft from the east, with period still short at 6 to 7 seconds. Combined energy is moderate, hitting 176 to 222. Still, the wind is howling from the east at 16 mph, and it’s cross-off, so the wave quality remains poor. The 10th morning is more of the same, but Thursday afternoon on September 10th – that’s the one small window worth mentioning. The swell hits 5 ft from the east, period bumps to 8 seconds, and combined energy jumps to 432. It’s still labelled “marginal,” but that’s the most juice we see in the whole run. For a reef break like Caballos, a bit of east swell with that moderate energy might just produce a few lined-up runners. The wind stays cross-off from the east-southeast at 16 mph, so it’s not glassy, but it’s workable for the experienced surfer. This spot is for advanced riders only, and with crowds listed as ‘sometimes’, you might have a few friends out, but it shouldn’t be a circus.
After that, from September 11th right through to the 20th, it’s back to the doldrums. Heights drop to 1 ft to 3 ft, periods are all over the place – 5 to 9 seconds – and the combined energy rarely gets above 100, often dropping into the 20s and 30s. It’s clean, but there’s nothing to ride. The wind stays a steady east or east-southeast cross-off at 12 to 16 mph, which just pushes the knee-high slop around. For the final week, from mid-September onward, the swell direction wobbles between northeast and east, but the energy is too scattered to get excited about.
So if you’re jonesing, your best bet is that Thursday afternoon on September 10th at Caballos. It’s not perfect, but it’s the only time in the next 16 days where the swell shows some real weight and the reef might come alive. Bring your patience and your biggest board for the rest of it.
Stay wet,
Rusty.

Information about the Caballos Surf forecast
The above surf forecast table for Caballos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Caballos can be found by selecting the local surf guide option on the grey menu. Our Caballos 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 (Caballos) 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 Caballos 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.
