The Lowdown
Alright, Rusty here again. Let’s break it down in feet and Fahrenheit.
The surf at Cabo Blanco kicks off this Monday morning. The water is running a touch warmer than usual for this time of year, at 86°.
Monday morning (27th July) is a top pick. There’s a 3ft southwest groundswell with a long 19-second period, meaning proper, lined-up waves with long lulls. The wind is glassy out of the east at 3 mph, so it’s going to be clean. The combined energy is strong (904). This is a solid morning for the experienced surfer.
Tuesday morning (28th July) is the real standout. The swell bumps up to 4ft, still from the southwest, with an 18-second period. Another glassy morning with a light easterly breeze. The energy is even higher (1097). This is the best session of the run—clean, powerful, and a bit too much for beginners, but perfect for anyone who’s comfortable.
Wednesday morning (29th July) holds at 4ft, period dropping to 16 seconds, with dead calm, glassy conditions. Energy is still strong (898). Another top-notch morning. Afternoons are all onshore and crummy, so make it early.
The swell eases through Thursday and Friday, but the glassy mornings still give you fun, clean waves in the 3ft to 4ft range. The water stays warm.
There’s a quiet spell over the weekend of the 1st and 2nd of August, with smaller 2ft to 3ft swell, but the early sessions are still glassy. It’s surfable, just not as meaty.
The magic returns on the 7th of August, Friday morning. A fresh 2ft southwest groundswell with a 17-second period, combined energy is strong (568), and the wind is dead calm. Then Saturday (8th) and Sunday (9th) mornings are both glassy with 3ft to 3ft southwest swell and periods in the 15-16 second range, with energy climbing back up (585 to 748). These are the standout mornings of the second week.
The run continues into Monday (10th) and Tuesday (11th) with glassy mornings, 3ft to 4ft swell, and solid energy. Crowds are “sometimes,” so you’ll have company but not a crowd.
The top sessions are Tuesday morning (28th July) and the glassy mornings around the 7th to 9th of August. Get out there.

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.
