The Lowdown
G'day, it's Rusty. We've got a solid run of surf on the cards here at Cabo Blanco (Peru), but you've gotta pick your moments. The next couple of weeks are packed with options, though the mornings are absolutely where it's at – the wind is the key, and the afternoons are a write-off most days.
We kick off Wednesday morning the 26th with tiny, glassy 2ft SW groundswell that's got a very long 15-second period. The wave energy is weak (177), so it's more about getting a feel for the water, but it's clean. The water temp is about average for this time of year, so nothing wild there.
Thursday morning the 27th is similar – 1ft SW swell, 18 seconds, glassy. Still small. The real fun starts to build on Friday morning the 28th. The swell has bumped up to 2ft from the SW, but with a 20-second period, the energy is building (350). Glassy conditions will make it look clean, but that long period means it'll be fat and walled up at the beach, so look for a point or reef if you're keen.
Saturday morning the 29th sees a proper step up. We've got 4ft of SW swell at 16 seconds, with moderate energy (668) and glassy conditions. This is the start of the good stuff. Sunday morning the 30th holds 4ft of SW swell (738 energy), and it's glassy again. The period drops to 14 seconds, which is a better shape for the beach.
Monday morning the 31st still has a clean 3ft SW swell (433 energy), and Tuesday morning the 1st of September bumps up to 3ft but with very good conditions and moderate energy (523). The pattern is clear: mornings are gold.
The standout window really starts to open up on Friday morning the 4th of September. That's a 4ft SW swell from a 17-second period, with glassy conditions and strong energy (969). The following Saturday morning the 5th has 4ft SW swell (919 energy) and glassy conditions. Both are top-tier, but the swell is getting up to 4ft, which is still fine for most, though beginners might want to be careful if it's a bit bigger.
If you're after the absolute pick of the bunch, look at Wednesday morning the 9th of September. We've got 4ft of SW swell with a 17-second period, glassy as a mirror, and strong energy (916). But the absolute best is Thursday morning the 10th of September. The swell is 4ft from the SW, 16-second period, and the energy is pumping (1226) – that's a very strong reading. It's glassy, and the forecast says "excellent surf conditions for experienced surfers." This one is a standout for those who can handle it. The 4ft isn't huge, but the energy and long period will make it powerful and lined up.
Crowds are 'sometimes' an issue, so the early morning crew will have the best of it. The wind is offshore or calm for most mornings, which is a massive plus for clean faces. Keep in mind, the long-period swells (15-20 seconds) will be best at a reef or point to avoid them closing out. The afternoons are mostly a no-go with onshore winds and storm risks.

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.
