The Lowdown
Alright, folks, let’s talk about what’s in the water. We’ve got a long stretch ahead, and to be honest, the first few days are a bit of a snooze. The first real opportunity doesn’t show up until the end of August.
The spot to watch is Caballos, a reef break that’s strictly for the advanced crowd. It’s an inconsistent setup, so when it works, it’s a special treat, but you gotta be patient. The water temp is about 85°F, which is pretty normal for this time of year.
The one day that stands out is Monday, August 31st. In the morning, you’ve got a 5ft swell coming from the ENE, building up a combined energy of 447 (moderate wave energy). The wind is offshore out of the SSE, so it’ll be clean. The swell period is 10 seconds, so it’ll have some shape. The afternoon drops to 4ft, but still clean. This is the only window in the whole 16-day run where the wind and swell line up properly.
After that, it’s a slow fade. Tuesday, September 1st, has small, clean waves in the morning, 3ft from the ENE, but the energy is weak (112), and the wind is cross-offshore. It’s surfable, but nothing to write home about.
Then we hit a major dry patch. From September 2nd all the way through to the 8th, the waves are tiny, from 0.3ft to 2ft, and the energy readings are in the teens and twenties – that’s flat. It’s a real lull.
We get a little bump on Wednesday, September 9th. The morning shows 4ft from the N, with a period of 12 seconds, and the combined energy jumps to 340 (strong wave energy). But the report says it’s only “marginal,” and the wind is cross-offshore from the east at 25 km/h. That longer-period groundswell would be beautiful on a reef, but the wind is just not cooperating.
So, if you only have one day to paddle out, make it Monday, August 31st. After that, it’s pretty quiet. This spot is known for being inconsistent, so a long gap like this isn’t a total shocker. Forecasts can change, but right now, it’s a waiting game.

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.
