The Lowdown
Alright my friends, Rusty here to give you the goods for Cabo Blanco. It’s a bit of a mixed forecast, but there are a few definite sessions to mark on your calendar. The water’s nice and warm right now at 87°F, which is about 4°F warmer than average — that’s a big deal for this time of year, so don’t bother with the wetsuit.
The next couple days are a bit of a write-off. Saturday the 1st has some small swell but the wind is all wrong and it’s looking poor. You’ll want to hold off until Sunday morning the 2nd — it’s only 2ft of SW groundswell with a 12-second period and it’s totally glassy. Small, but clean.
The big standout is Saturday morning, the 8th of August. This is the pick of the trip. We’ve got a clean 4ft SSW swell running with a long 16-second period, and the wind is dead calm — just perfect glass. The combined energy is pumping at (741), so there’s some real punch behind those waves. The direction is right out of the SW which is ideal for this spot. It’s not too big for a good intermediate surfer, but that long period will really push through — point and reef breaks will handle it best. There will be some lulls between the sets, but when it comes through, it’ll be worth the wait. The place sees crowds sometimes, but on a morning like that, if you’re early, you’ll score.
We’ve got another really nice setup on Saturday morning, the 15th of August. That’s a 3ft SW swell with a 16-second period and glassy conditions again. The energy is strong at (553). Slightly smaller than the 8th, but still very clean and lined up.
One to watch is the morning of the 12th — only 2ft of SW swell with a 16-second period, glassy and clean. That’s for the loggers and the small-wave crew.
After the 8th, the afternoons start to get a bit messy with the sea breeze, so stick to the early sessions. The long-range stuff around the 14th and 15th looks good on paper, but it’s a way out so keep an eye on it. The 8th is your clear winner. Don’t miss it.
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.
