The Lowdown
Alright folks, Rusty here. Let's have a look at what the next couple of weeks have in store for us. I gotta be straight with you right off the bat – the outlook for Caballos is pretty grim for a long stretch. There's not a single standout day in this whole 16-day window where you’d want to drop everything and paddle out. The opening days, starting Friday the 11th of September, have barely any swell to speak of, and what’s there is weak and messy.
We kick off with a bit of waist-high 3ft energy coming out of the ENE, but it's being torn apart by a 25 km/h cross-offshore wind, making it choppy. The water temp is sitting at 85°, which is about average for this time of year, so that's one small comfort. But the energy is weak, and it goes downhill from there. The swell drops to tiny 1ft or 1.0ft for days on end with periods around 8 or 9 seconds, and that same pesky cross-off breeze from the east hangs around. This is basically a blank run for paddle surfing. For a spot that’s inconsistent and rarely works, this run is not unusual at all – it’s just a long stretch of flat, blown-out days.
The middle of the following week, around the 18th of September, the swell tries to bump up a bit to 3ft again, but the period is a shocking 6 to 7 seconds – short period, gutless slop. The energy is moderate, but the wind remains a problem. On the 24th of September, there’s a tiny uptick to 2ft from the north with a period of 10 seconds, producing moderate energy, but again, that wind is relentless. By Saturday the 26th of September, we see the most interesting wave of the forecast: 2ft with a period of 11 seconds from the north. That longer period suggests the shape might be a little cleaner, but the wind is still 25 km/h cross-off. For a reef like Caballos, this could still be junk. Honestly, with that much wind and the small, weak swell, this setup looks more interesting for kite surfing than paddle surfing over most of the period.
The stark reality is there are no good surf options here in the 16-day window. A lot of consistent, small scraps that just won't be rideable. Don't lose hope though – it tends not to stay this bad forever, and forecasts can change.

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.
