The Lowdown
Righto, let’s have a look at what’s lining up for us at Cabo Blanco. This exposed southwest-facing spot is about to see a run of glassy mornings and a decent pulse of long-period groundswell that’s got my hopes up, but we’ll need to pick our windows carefully because the afternoons turn to junk.
The pattern starts from Thursday morning, July 30th. It kicks off with a clean 4ft swell from the southwest, a solid period of 14 seconds, and glassy calm winds. The combined swell energy is sitting at a moderate 507 – feels like there’s a bit of grunt in the water. At this size, it’s good for most experienced surfers, a little on the bigger side for beginners. The water temp is about normal for this time of year, nothing unusual there.
That Thursday morning session looks like the real deal – clean, lined-up, and that long-period swell will wrap in nicely. This is your standout of the first few days. Be aware though, crowds are possible here at times, so get in early. By Thursday afternoon the seabreeze swings onshore and it’ll get messy – steer clear.
Friday July 31st through Sunday August 2nd keeps the trend going: clean glassy mornings with swell hanging around the 2ft to 3ft range from the SSW, periods around 12-13 seconds. The energy drops a little (276 to 241), but it’s still fun, clean surf for a morning paddle. The afternoons all fall apart with onshore wind and stormy conditions.
Monday August 3rd and Tuesday August 4th offer more of the same – glassy starts, then blown out. Tuesday morning sees the period drop to 9 seconds, which makes the waves a bit weaker and less organised, but still rideable if you’re keen.
Then things get pretty quiet. From Wednesday August 5th through to Thursday August 6th, the swell drops right off – we’re looking at 1ft to 2ft with combined energy down to 138. It’s surfable but ordinary, and definitely not worth getting excited about.
Now, here’s where it gets interesting again. Friday August 7th morning – glassy, 2ft but with a very long 18-second period from the SSW, and the combined swell energy jumps to 561. That’s a proper groundswell pulse. The long period means it’ll have heaps of push and shape, but it might be a bit straight for the beach break – Cabo Blanco is a beach-and-reef setup, so it could handle it nicely. This is another standout, but it’s a week and a bit away, so keep an eye on it.
Saturday August 8th morning is the big one if you ask me. 4ft of SSW swell, 16-second period, glassy winds, and combined energy of 914 – that’s strong, powerful surf. This is best for experienced surfers only; over 5ft starts pushing into bigger territory. The long period means long gaps between sets, so paddling out won’t be a battle. This is the best session on offer in the whole outlook.
Sunday August 9th morning keeps it clean with 4ft, 14-second swell, and calm winds. Then it gradually fades through to mid-August, with mornings holding 2ft to 3ft and decent periods until around August 14th, when it drops off again.
To be honest, after that first Sunday, nothing else really screams “drop everything and go.” The week of the 10th to the 14th is all about small, clean morning waves with consistent 2ft to 3ft fun, but no real power. The afternoons all get wrecked by onshore wind.
So, two true standouts: Thursday July 30th morning for the clean start and solid energy, and Saturday August 8th morning for the bigger, powerful groundswell with glassy conditions. If you can only pick one, aim for that 8th – it’s got the size and the juice.
Stay patient, pick the mornings, and you’ll score.

Information about the Cabo Blanco Surf forecast
The above surf forecast table for Cabo Blanco provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cabo Blanco can be found by selecting the local surf guide option on the grey menu. Our Cabo Blanco 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 (Cabo Blanco) 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 Cabo Blanco 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.
