The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for Cabo Blanco over the next couple of weeks.
Right off the bat, we’re in a patch of small, clean surf. The water is sitting at 86°F – that’s over 4°F warmer than usual for this time of year, so the ocean feels like a bath. The standout is Tuesday morning, July 28th. We’ve got a solid 4ft SW groundswell rolling in with a very long period of 18 seconds, and the wind is glassy from the east. The energy is pumping hard (1097), and this is where it’s at for experienced surfers. That long period means the waves will have real shape and power, perfect for a lined-up point break. Later Wednesday morning, July 29th, is also a beauty: 4ft SW swell, glassy, and clean.
The first week shows a pattern of clean mornings getting chopped up by afternoon thunderstorms and onshore wind. Sunday morning, July 26th, had 3ft SW swell with glassy conditions, but the weekend crowds are a factor here – Cabo Blanco can get busy, especially with a consistent SW swell and such good conditions.
After the 29th, the swell drops a little. Thursday morning, July 30th, is still surfable at 4ft SW, but the period drops to 14 seconds, and by afternoon it’s onshore junk. Friday and Saturday mornings, July 31st and August 1st, bring back some glassy windows with clean 3ft SW swell, but the energy is winding down (337 then 290). The following week, from August 2nd to the 5th, is a real lull – we’re looking at 2ft to 2ft leftover swell, with a couple of glassy mornings but nothing to get excited about. The energy dips to a weak 131.
Then, just when you think it’s over, the second week picks up. Thursday morning, August 6th, sees a new pulse: 4ft SSW groundswell, period 15 seconds, clean glassy conditions, and energy climbing back to 565. Friday morning, August 7th, is even better – 4ft SSW, glassy, calm, with energy at 592. That’s the real long-range standout, but it’s a week and a half away, so keep an eye on it. The pattern holds for Saturday and Sunday mornings, August 8th and 9th, with 3ft and 3ft SSW swell, clean and glassy, but the period is dropping to 11-12 seconds by then.
All in all, Cabo Blanco is offering a classic run of clean, glassy mornings with a solid SW groundswell, a few days of small stuff, then a second pulse. The best surf is definitely on Tuesday morning, July 28th – that’s your pick of the fortnight. The far-off Friday, August 7th, is a promising bet too, but don’t hold me to it yet.

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.
