The Lowdown

Alright, Rusty here. Let’s break down what’s comin’ for Cabo Blanco.

The first real chance to get wet hits Sunday morning, the 30th of August. That morning is the standout early call: a 4ft SW groundswell with a long 14-second period and the wind is dead calm – glassy as it gets. The water’s running about 4°F warmer than average for this time of year, so it’s comfortable out there.

Don’t bother with Saturday the 29th afternoon – cross-onshore wind and storm risk kill that session. The combined swell energy (900) is decent, but the wind just ruins it.

The real showstopper further out is Friday the 4th of September. That morning looks clean with 4ft of SW groundswell and a 17-second period – that’s proper long-period groundswell. Combined energy hits 952 (moderate-strong), and with glassy conditions, you’re lookin’ at lined-up, clean sets. This swell direction is spot-on for the break. It’s a week away, so don’t bet the house on it, but it’s the one to circle.

After the first Sunday, the surf drops off but still offers small, clean windows on many mornings. The 8th and 9th of September have some glassy starts with swell around 3ft, but it’s more for the groveler than the charger. The 11th of September morning also stands out with 4ft of SW swell at 16 seconds in calm conditions – energy around 752 – that’s a fun, quality session.

The second half of the outlook fades fast. By the 13th of September you’re lookin’ at 2ft of SW swell but with a very long 19-second period. That’ll be too straight for most beach breaks, but if you find a point or a reef, you might snag a few clean, slow lines.

Overall, Sunday the 30th and Friday the 4th are your honest best bets. The rest is small and clean in the mornings, but nothing to write home about.

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.
