The Lowdown
Alright, Rusty here. Let's break it down.
The next sixteen days are a slow burn with a long gap at the start. The first ten days are pretty much a dud, with next to no surfable waves. Then, things finally show some promise in the final days.
The water at our main spot is a balmy 85°, which is just about normal for this time of year.
Caballos is the only game in town, and it's a tough one. From the 14th through the 24th of September, expect tiny, weak swell and messy onshore winds. Most days have waves under 3ft with short periods, and the energy is almost non-existent. It's a complete washout.
The turnaround starts on the 25th of September. That Friday morning, the swell picks up to about 3ft from the north-northeast with a period of 11 seconds. The energy jumps to 395, but the wind is still cross-shore, making it only marginal. The real standout is the Friday afternoon. The wind swings offshore from the southeast, giving us clean 3ft waves with a 12-second period and energy at 391. That's your best bet for a session.
The weekend of the 26th and 27th still offers some hope with 3ft to 4ft swell from the north-northeast and periods around 12 seconds. However, the wind is back to a cross-off breeze, so it won't be as perfect as that Friday afternoon. The energy remains strong, hitting 414 on the Saturday morning. It's good, but not the best.
So, to put it straight, the one true standout is the Friday, 25th of September afternoon. That's your clean, offshore window with a proper groundswell. The rest of the time, Caballos, being an inconsistent reef break, will be mostly flat or blown out. But when a rare spot like this lines up with an offshore breeze, it's something to get excited about.
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.
