The Lowdown
Alright, let’s talk the same story in feet and miles per hour, because that’s how some of us think.
The next two weeks at Caballos are mostly a flat spell with a whole lot of east wind blowing across the lineup. The water’s about 84°F, which is pretty normal for this time of year—nothing unusual.
We start on Thursday, August 20th, with a weak 3ft east swell, but it’s only got a 6-second period and 30 km/h cross-off wind. It’s a washout. The combined energy is a weak 88. Friday and Saturday the 21st and 22nd are even smaller—1ft to 1ft—with the same wind. The energy is in the teens to low 40s. It’s clean, but there’s nothing to ride. Sunday and Monday follow the same pattern: tiny waves, energy in the single digits.
Then Tuesday, August 25th, we get a little bump. The afternoon shows a 5ft east swell, 7-second period, and a light offshore southeast wind at 20 km/h. The energy climbs to 186 (moderate). It’s “surfable but ordinary,” and it’s the only time that week that’s even worth a look. The water is clean.
The next few days, August 26th through 28th, are back to the same cross-off east wind. The swell sits around 3ft to 4ft, but the energy is moderate (125 to 160) and the surf quality is poor. Winds are a steady 25 km/h, so it’s bumpy.
Now, for the experienced crew, mark Sunday, August 30th. The morning brings a 6ft east swell, 7-second period, and cross-off winds. The energy jumps to 641 (strong)—that’s the biggest push of the whole forecast. The wave comment says “marginal,” so it’s not a classic, but for a reef that’s usually inconsistent, this is the best you’ll get. The afternoon settles to 5ft with energy at 281. Both windows are clean, but that short period means the waves are a bit soft.
After that, it’s a slow fade. Monday, August 31st, drops to 3ft, and from Tuesday, September 1st, through to Friday, September 4th, it’s all 1ft to 2ft with periods between 8 and 11 seconds. The energy is under 50 (weak). The winds are cross-off, and the surf is poor.
The standout: That Sunday, August 30th morning. The 6ft east swell with 641 energy is the only real pulse. It’s not perfect, but for a reef that’s often quiet, it’s your best shot. Expect some company, though—crowds are “sometimes” at Caballos.
The rest of the 16 days? Flat and frustrating. Keep your board waxed, but don’t expect much.

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.
