The Lowdown
Alright folks, Rusty here. Let’s break down what’s on the menu for the next couple of weeks. We’re looking at a pretty consistent run of small but clean surf, with a couple of standout sessions that’ll have you grabbing your board.
The overall pattern is a prolonged period of mostly glassy or offshore mornings, with the afternoons getting chopped up by onshore breezes. The swell ticks all the right boxes direction-wise, coming in from the SW and SSW, which is exactly what Cabo Blanco wants to see. The water is sitting at 86°, which is a touch warmer than normal for this time of year, so you can leave the thick wetsuit at home.
Cabo Blanco is your only show in town, and it’s a good one. The immediate standout is Thursday morning, July 30. We’ve got a clean 4ft swell from the SW, with a solid 14-second period pushing through. The combined energy is moderate (507), but the real story is the absolute glass-off conditions—zero wind. This is going to be smooth, silky, and very, very good. This is the pick of the trip for the first week.
Friday morning, July 31, is another solid option with 3ft of SSW swell under glassy skies. The wind goes calm again, making for a super clean session. Saturday and Sunday mornings (August 1 & 2) are also in the mix, with a light offshore on Sunday helping to keep the 2ft SW swell clean. These are all solid, but nothing touches Thursday.
Looking further out, there’s a notable little bump of energy arriving on the morning of Friday, August 7. We see a 2ft SSW groundswell with a very long 18-second period, pushing the combined energy to 454. The wind goes glassy again. This could be a real gem—very long period swells like this can offer some beautiful, lined-up waves at a point like Cabo Blanco, with plenty of time between sets to get back out. It’s a bit further out in the forecast, so keep an eye on it, but the early signs are promising.
Then Saturday morning, August 8, looks even better on paper. A similar 3ft SSW swell, but with a 16-second period and combined energy of 544. Again, glassy conditions. If that holds, that’s another top-tier session.
The mornings of August 9 through 14 all offer clean, glassy conditions with waist-high SSW to SW swell in the 2ft to 3ft range, with periods between 13 and 17 seconds. It’s consistent, it’s clean, but it’s not going to blow your socks off like the July 30 or August 8 mornings. The afternoons are a write-off across the board due to onshore SW winds.
The call: Get out there Thursday morning, July 30, and keep your fingers crossed for that Saturday, August 8 session. The rest of the mornings are the perfect backup plan for a no-stress paddle.
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.
