The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a grim stretch for Cabo Blanco. The entire 16-day window is a write-off. There’s nothing worth paddling out for, not a single session that cracks the surface. We’ve got a long, empty gap right from the start, all the way through to the end of the forecast on the 3rd of September. This isn’t a case of waiting it out; it’s a full-on drought.
The water is far warmer than normal for this time of year, sitting at 76.3°F on the 19th of August (anomaly of 10.6°F), which is very unusual. But that’s about the only thing that’s out of the ordinary.
You’ll see weak swell pulses, mostly from the SW, with heights barely scraping 2.6 ft to 3.6 ft, and periods so short – 3 to 5 seconds – they’re just wind slop. The combined wave energy is consistently weak, often in the single digits or low teens (like 4 or 7), and the highest we see is a paltry 63 on the 23rd of August afternoon. That’s still weak energy. The wind is nearly always a cross-shore or cross-onshore breeze, often fresh or strong, churning up a lumpy, messy cross-chop. There are a couple of glassy mornings on the 27th of August and the 1st of September, but with no swell to speak of, they’re flat and useless.
The swell is mostly from the SW, which is a long way off the optimum NNW direction for this point break. Even that tiny 3.6 ft pulse on the 20th of August is a 4-second period – total junk. For a consistent, exposed point like Cabo Blanco, this is just a blank run. It happens. Forecasts can change, but right now, there’s nothing here for a surfer.

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.
