The Lowdown
Alright folks, Rusty here. Let’s talk about the next couple of weeks.
We’ve only got one spot on the radar, and that’s Caballos, a real reef setup that doesn’t fire often. The next few days are a write-off – small, weak, crummy wind conditions. You’re looking at a real flat spell until we get into the second week. Things are looking pretty average for the most part, but there is one window that has me sitting up a bit straighter.
Saturday, August 29th through to the end of the first week is mostly forgettable. Swell is small, around 2 ft to 5 ft, mostly from the ENE, with a short, weak period of 7 seconds. Wind is a steady cross-off or cross-shore breeze, which isn't doing us any favours. The water temp is about 0.8° warmer than usual for this time of year, sitting at 85°, but that’s not much comfort when the surf is flat.
There’s a brief pulse of life on Sunday, August 30th in the afternoon. We see a jump to 7 ft from the ENE with a 10-second period and a clean offshore wind. The energy kicks up to 856 – that’s moderate to strong energy. This is a decent window for those who know the reef, but it’s inconsistent and it’s a Sunday, so expect a few others sniffing around.
From Monday, September 1st through the first part of the second week, it’s back to small, weak, and pretty ordinary. Swell drops right off, with heights under 3 ft and energy levels dipping into the double digits. We’re talking a long stretch of nothing really worth paddling out for.
Now, here’s the standout. Sunday, September 6th early morning looks like the best bet of the entire forecast period. A clean 8 ft swell from the ENE, with a long 11-second period, and only a light breeze. The combined energy is 1198 – that’s strong. This is proper groundswell, and it’ll be too much for beginners. The reef at Caballos should handle that long-period energy nicely, offering some proper, powerful waves. It’s inconsistent, so you’ll need some patience, but if you sit in the right spot, the rewards could be big.
After that, the energy fades again. The rest of the second week into September 13th is pretty marginal, with small, short-period swell from the north-northeast and side-shore winds. Nothing to get excited about.
So, the one to circle on the calendar is the morning of Sunday, September 6th. It’s a promising long-range call – less certain this far out, but if it lines up, Caballos could be the spot. If you’re an experienced surfer, that’s your window.
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.
