Table - best surf conditions forecast for Cabo Blanco over the next 16 days.
Alright, let’s talk about this. Cabo Blanco is the spot for the next couple of weeks. We’ve got a real nice run of waves coming in, nothing too huge, but a whole lot of clean, fun surf.
First thing, the water is 87°F, which is way warmer than usual for this time of year. It’s really nice.
The standout is Thursday, July 9th. We’re looking at 4ft of SSW swell with a 15-second period – that’s a proper groundswell. The energy is moderate at 655, and the wind is glassy out of the NW at 3 mph. It’s going to be perfectly clean. The long period will give you some nice, lined-up waves, especially on a point or reef, but it’ll be fun anywhere. Just be ready for longer waits between sets.
Friday morning, July 10th, is another good one. The swell drops a little to 3ft, still from the SSW and still a long 15 seconds. The energy is 511, but again, glassy wind from the SE at 3 mph. Clean conditions.
Saturday morning, July 11th, is probably the best of the early run. The swell bumps up to 4ft, still from the SSW, with a 16-second period. The energy is up to 816, so there’s some real power in the water. And with the wind glassy out of the NW at 3 mph, it’s just perfect. This is the one to aim for.
Sunday morning, July 12th, keeps it going. 4ft SSW swell, 14-second period, glassy wind from the NW at 3 mph. Energy is 580. More of the same good stuff.
Monday morning, July 13th, is a little smaller at 3ft, but the wind is dead calm. That’s a glassy, smooth surface. The energy is 566, and the swell is still a clean 13-second SSW. It’s a perfect small-wave day.
Tuesday morning, July 14th, is another morning with a 4ft SSW swell, 14-second period, and glassy east wind at 3 mph. Energy is 468. Clean and fun.
Wednesday morning, July 15th, is a carbon copy. 4ft, 14-second SSW swell, completely calm wind. You’ll be surfing on glass.
After Wednesday, the pattern gets a little more mixed. The mornings are still good, but the afternoons get choppy. Friday, July 17th, morning is a standout with a 4ft SSW swell, 14-second period, and glassy NW wind. The energy is 567. Get it in the morning before the wind shifts.
Saturday, July 18th, morning is the same deal. 4ft, 13-second SSW swell, glassy NW wind. Energy is 511. A morning mission.
There’s a bit of a lull for a few days mid-week, with smaller surf, but it picks up again on Wednesday, July 22nd, with a 3ft SSW swell, 12-second period, and zero wind. The energy jumps to 580. That’s a good sign.
The real wildcard is Friday, July 24th. The swell jumps up to 6ft from the SSW, with a 12-second period, and the energy is a hefty 1026. That’s a lot of water moving. The wind is cross-shore at 6 mph, so it won’t be perfect, but for a bigger wave, it’s a good option. Just be aware, at 6ft, it’s getting into the territory where it’s less for beginners.
Overall, the first 10 days are a dream. The swell is consistent, the wind is glassy every morning, and the water is warm. The later part of the outlook has a few bigger, more energetic options, especially on the 24th, but the wind is a bit more of a factor. If you’re looking for the best, lock in Saturday, July 11th, and Friday, July 17th mornings.

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.
