The Lowdown

Right then, let’s switch it up. The same story, just in feet and Fahrenheit for you lot who think in those numbers.

First up, we’ve got a really solid run coming. The backbone is a long-period SW groundswell that sticks around for ages, and the mornings are where you want to be. Afternoons get a bit stormy and onshore, but early? That’s the ticket.

Monday morning (24 August) greets us with a glassy 2ft SW swell, period hanging at 18 seconds. That’s a very long-period groundswell. The combined energy sits at 345 – moderate but with plenty of push. Water temp is pretty normal for this time of year. No wind. Cabo Blanco, it’s a clean start.

Tuesday (25 August) and Wednesday (26 August) mornings stay clean with 2ft waves, but the energy dips a touch. Still fine for a longboard.

Hold on, because Saturday morning (29 August) is where it starts to get good. Swell bumps to 4ft from the SW, period still a meaty 16 seconds, and the combined energy hits 661 – that’s moderate to strong. Glassy again. Conditions are very good.

Sunday morning (30 August) keeps it going: 4ft SW, period 14 seconds, combined energy 732. Proper. But the real standout? Friday morning, 4 September. Swell is 4ft from the SW, period 18 seconds, combined energy 1035 – strong. Glassy wind. This is excellent for experienced surfers. Plenty of power.

And Saturday morning, 5 September is just as good: 5ft SW, 16-second period, combined energy 1085 – strong. Glassy. These two mornings are the peak of the run. Don’t miss ‘em.

Cabo Blanco loves that SW swell, and with those long periods, the waves will have plenty of shape. It’s fairly consistent here, and crowds are just “sometimes,” so you won’t be fighting for every wave.

After the 7th, the energy drops and the winds get a little cross-on. Still surfable, but that first week of September is the sweet spot.

Get on it. The 4th and 5th are the ones to circle.

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.
