The Lowdown
Alright, Rusty here. Let’s have a look at the coming weeks.
Honestly, it’s a tough stretch ahead for Cabo Blanco. Right now through the middle of September, the surf is nearly non-existent. There’s barely a ripple out there from Monday the 31st of August through to around the 8th of September, with wave energy staying flat and the numbers pathetic – mostly under 20 (combined energy). On the 4th of September Friday morning we get a brief moment of glassy conditions, but with a tiny 0.3ft NW swell and a period of 11 seconds, it's almost nothing. That’s not really surfable.
There’s a shift around the 8th of September Tuesday afternoon – the combined energy bumps to 57, still small (1ft, NW, 12 seconds), but it’s the first sign of life. Wednesday the 9th of September morning sees similar (60 energy). Those little windows are cross-shore winds though, so shape is going to be average. The wave period is getting longer (12 seconds), which adds a bit of grunt, but the size is still well under 3ft.
The best of a bad run looks like it may shape up from the 10th of September onward, with combined energy hovering in the 60 to 90 range and swells coming from the northwest at 1ft to 2ft. It’s not going to blow your hat off, but the period stays above 11 seconds which means these are groundswells, better for a point break like this one (Region is Peru, by the way). Wind is cross or cross-off most of this time, with a few mornings seeing a lighter breeze – that’s your best bet for a cleanish wave. However, crowds are often here, so expect company.
But here’s the honest truth: There isn’t one standout session across these 16 days. The water is far warmer than normal at 77°F with a massive anomaly of 12°F – that's very unusual, freakishly warm for the time of year. The swell just never gets above maybe 2ft at best, and the energy barely cracks three digits. For advanced surfers, there’s almost nothing to work with. For beginners? Even the tiny swells might be okay, but it’s not worth a trip.
In short, if you’re a kitesurfer, some of those afternoon cross-shore breezes might get you moving. For paddle surfing? It’s mostly a flat spell with a few very marginal days. Forecasts can change, but right now this is a big ol’ blank run.
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.
