The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Cabo Blanco. We got a solid run of surf on the way, but we gotta wait for the right windows.

The story for the next couple of weeks is all about that consistent, long-period SW groundswell. It’s not gonna be huge by any means, but there’s some real quality if you pick your moments. The main event is definitely the first few days, starting Thursday morning, September 10th. We got a nice 3ft swell from the SW with a 15-second period, and the wind is looking glassy as all get-out – offshore out of the W at 3 mph. That's prime-time, rippable conditions. Combined wave energy is solid at 587 (moderate). Then Friday morning, September 11th, is the other absolute standout. It’s dead calm, glassy, with a clean 3ft SW swell at 16 seconds. Energy is at 561 (moderate). This is as good as it gets for a smaller day.

Now, the water is noticeably warm, running about 3°F above the norm for this time of year at 86°F, so a touch warmer than usual – you can probably get away with a shorty or spring suit.

Let’s break it down. For the best sessions, you wanna hit Cabo Blanco early. That Thursday morning (Sep 10) with the glassy conditions and that pure SW groundswell (15 sec) is going to be clean as a whistle. Crowds can be a factor here *sometimes*, so the early bird gets the worm. Friday morning (Sep 11) is the other absolute gem with that same clean, lined-up swell.

We’ve got a bit of a gap in quality after the weekend. The mornings on Saturday the 12th and Sunday the 13th offer clean conditions with smaller 2ft to 3ft SW swell, but the energy dials back a bit (around 287 to 347). Mid-week gets messy with onshore winds picking up. Then we get a second wind towards the end of the second week. Look at Sunday morning, September 20th – we get a nice 2ft SW groundswell with a very long 19-second period and clean cross-offshore wind from the NW. That’s a sleeper session for the point. Energy is up at 457 (moderate). The following Monday morning (Sep 21) also has clean cross-off wind and a 2ft SW swell with 18-second period.

Just be aware, the afternoons pretty much all week are going to get messy with those storm risks and onshores. Keep it to the early mornings for the best of it. That Thursday and Friday morning are the standouts – get after 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.
