The Lowdown
Alright, folks, Rusty here. Let’s break down what’s cooking for Cabo Blanco. We’ve got a solid run of small, clean surf on the horizon. Nothing huge, but plenty of fun waves for a longboard or a mid-length. The water is sitting at 86°—a touch warmer than usual for this time of year.
We kick off this Friday, July 31st. The morning is looking sweet with a 3ft swell from the SSW and glassy conditions. The wind is dead calm, so it’s going to be clean. That’s a 13-second period, so there’s some decent groundswell energy in the water. Nice and easy to paddle out. The afternoon gets a bit messy with cross-on wind and a risk of t-storms, so get your session in early.
Saturday, August 1st is much the same. Another glassy morning with a 3ft swell from the SSW. The afternoon turns onshore and makes things less appealing. Sunday the 2nd is another winner in the morning, with 2ft from the SW and glassy, clean conditions. The swell energy is a bit lower, but it’s a long 12-second period, so the waves will have shape.
Monday morning the 3rd is glassy again with a 2ft, 14-second swell from the SW. It’s small, but clean. Tuesday the 4th rolls in with a similar story: 3ft in the morning, glassy, but the swell period drops to 9 seconds, so it’s a bit weaker.
Now, let’s talk about the first real standout. Jump ahead to Friday, August 7th. The morning is going to be a beauty. The swell is only 2ft, but it’s a very long 18-second period from the SSW. That’s a proper groundswell, and the energy jumps way up. The wind is calm, glassy. This is a spot where that long period will wrap in nicely, and the sets will be clean and well-defined.
The next big one is Saturday, August 8th. Another morning standout. The swell picks up to 4ft from the SSW with a 16-second period. The energy is strong and the wind is glassy. This is probably the best on offer: clean, solid, long-period swell. Not too big for most, but it’s got some push. The afternoon turns messy again with cross-on wind.
We get another solid morning on Sunday, August 9th, with 4ft from the SW, 14 seconds, and glassy conditions. The energy is still strong. Then we have a run of smaller, clean mornings through to the 11th, but the next big standout is on Friday, August 14th. The morning shows 2ft from the SW but with a very long 19-second period. The energy is strong and the wind is glassy. Another fantastic morning for a long-period groundswell.
The last big one in the forecast is Saturday, August 15th. Morning again, 3ft from the SW, 17 seconds, glassy, with a very strong energy reading. This is a promising one, but it’s far out, so keep an eye on it.
So, the best of the best? Saturday, August 8th morning for the best combination of size and cleanliness, and Friday, August 14th morning for that incredibly long, glassy groundswell. Crowds are possible at Cabo Blanco sometimes, but with these smallish sizes, it shouldn’t be too crazy.
Rusty.

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.
