The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks down at Cabo Blanco. We’ve got a proper run of swell on the cards, but you’ll have to pick your moments to dodge those afternoon storms.

Right out of the gate, we’re looking at a gentle pulse of long-period groundswell from the SW arriving late Wednesday afternoon, but it’s small, only 2ft, and the wind is onshore and messy with a risk of thunderstorms. That first day is a write-off really, the energy is there (464) but the conditions just aren’t cooperating. You’re better off waiting.

The real story starts Thursday morning, the 3rd of September. The swell bumps up a notch to a clean 3ft from the SSW with a solid 12-second period and glassy conditions. The water is a touch warmer than normal at 86°, which is nice, and the combined energy is ramping up (542). That’s a solid morning window to get some fun, lined-up waves all to yourself before the wind shifts. Friday morning and Saturday morning follow a similar vibe: glassy, clean, and building slightly. By Saturday, we’re seeing 4ft of SW swell (873 combined energy) and offshore NE winds. That is your top pick in the first week – Saturday morning the 5th of September. It’s got the size, the direction is matching what the spot loves, and it’s dead clean. Just know that crowds can happen here, so get out early.

Sunday morning the 6th is another cracker with 4ft and calm winds, but the swell period starts to shorten a bit, dropping to 15 seconds. That’s still a proper groundswell though, and the energy is moderate (667). The mornings are consistently the go. Afternoons? Forget it – thunderstorms and onshore breezes ruin the fun.

After the first weekend, the swell settles back a bit. Monday the 7th still delivers waist-high glassy waves in the morning, but by Tuesday the 8th we get a spike in period up to 18 seconds, but only 2ft of swell. High period like that can get a bit walled on a beach setup, but at a point break reef like Cabo Blanco, it should wrap in smooth and lined-up – that’s a good thing. The energy is still moderate (506).

Looking into the second week, the pattern holds steady. Morning sessions are your friend. Wednesday the 9th, Thursday the 10th, and Friday the 11th all have glassy starts with waist-to-chest high waves, around 3ft, and combined energy holding in the moderate range (395 to 586). The Saturday the 12th is smaller, dropping to 3ft, but again – dead calm in the morning. There are no absolute standout bombs in the second week, but the consistency is there. If I had to pick one distant highlight, Tuesday the 15th of September shows a bit of a bump back up to 4ft with calm ENE winds and decent 14-second period. That’s a promising one to keep an eye on, but we’re two weeks out, so don’t set your watch by it yet.

The water is running a touch warmer than normal for this time of year, so you can leave the thick wettie at home.

Bottom line: This is a morning-only surf forecast. The afternoons are a no-go. The absolute best window is Saturday morning, September 5th – get on it. The whole stretch from the 3rd to the 7th has good morning potential. After that, focus on the glassy windows and don't sleep on Tuesday the 15th.

Stay stoked.
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.
