The Lowdown

Alright folks, Rusty here. We’ve got a solid run ahead for Cabo Blanco, so let’s get into it.

The opening days are a bit of a slow burner, but the pattern is set for a decent stretch of fun-size southern hemi groundswell hitting that exposed SW corner. The first real standout is Saturday morning, August 8th. We’re looking at a clean 4ft of SW swell with a nice 16-second period, and the wind is glassy from the NW. The water is a touch warmer than normal at 86°, and the combined energy is moderate (656). This is your best shot early on – clean, long-period lines with that lovely glassy surface. Crowds are a possibility here, but it’s worth it.

The energy drops a touch through Sunday and Monday mornings, but with glassy conditions and solid 14-15 second periods, those mornings will still offer clean, rideable waves. Tuesday morning, August 11th, is a sneaky one – a tiny 2ft of swell but with a very long 18-second period and glassy WNW wind. The energy is moderate (346), and that long period will make it pulse through, best for those who know how to pick off the bigger sets at a point or reef.

Now, if you’re looking for the true standout of the whole run, keep your eyes on two sessions. First, Friday morning, August 14th: 3ft of SW swell, 18-second period, glassy WNW wind, and the combined energy is strong (677). That’s a beautiful combo. Then, Saturday morning, August 15th, is a real contender for the best of the lot. 4ft of SW swell, 16-second period, and absolutely dead calm, glassy conditions with ESE wind at 0 mph. The energy is strong (753). This is as good as it gets for a clean, mid-sized, long-period south swell session. Thursday morning, August 20th, also looks promising with 3ft of SSW swell and glassy NW wind, strong energy (555).

The afternoons are a write-off for most of the run – the wind turns onshore from the SW or WSW, bringing storms and choppy conditions. Stick to the mornings. The consistency is fairly good here, so even the smaller glassy mornings through the second week (like the 21st and 22nd of August) will offer a clean, if small, wave on your longboard or a fun fish.

The best on offer? Saturday morning, August 15th – glassy, 4ft of SW groundswell, strong energy. That’s the one to circle.

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.
