The Lowdown
Alright, my friends, Rusty here with the lowdown on the waves coming our way. We’ve got a solid stretch of surf, with a couple of mornings that are gonna be absolutely firing.
It all starts on Wednesday, July 29th. A nice pulse of SW groundswell hits, and the early session is the one. Cabo Blanco has 4ft of clean SW swell, with a super long 16-second period. The wind is dead calm, glassy as a lake. The combined energy is a solid 898 (moderate), and it’s coming from the right direction for this spot. This is a morning to remember. Expect very good surf. The afternoon turns onshore, so be there at dawn.
Thursday, July 30th is another morning special. The swell drops to 4ft, still from the SW with a 14-second period. Once again, glassy conditions, no wind. Energy is 498 (moderate). Good waves, but not as heavy as the day before. The afternoon is a write-off.
Friday, August 1st and Saturday, August 2nd the swell is down to 3ft, but the mornings are still clean and glassy. Fun, rideable waves. Then we get a bit of a lull on Sunday, August 3rd with 2ft surf.
Now, for the real gem. Look at Saturday, August 9th and Tuesday, August 12th. On Saturday, August 9th, the morning is clear with a light SE breeze, leaving it glassy. Swell is 3ft from the SSW with a 14-second period, and the energy is 539 (moderate). Very good surf is expected. Then Tuesday, August 12th is the absolute winner. Clear skies, zero wind, dead glass. Swell is 3ft from the SSW with a 14-second period, and the energy is pumped up to 565 (moderate). This is the session to circle on the calendar. Clean, punchy, and from the right angle.
Water temp is about where it should be for this time of year, so no worries there.
That long period (14-16 seconds) early on will give you some great shaped waves, but you’ll have to be patient between sets. And Cabo Blanco can get a crew sometimes, so get out there early to claim your spot.
The rest of the window stays rideable. Monday, August 11th morning has a glassy 2ft of SSW swell, and Thursday, August 13th morning has 3ft of SW swell, also glassy.
So, the two big ones: Wednesday, July 29th for the biggest punch, and Tuesday, August 12th for the most perfect conditions. Don’t miss them.
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.
