The Lowdown

Alright folks, Rusty here. Let's have a look at the upcoming swell window for Cabo Blanco.

We've got a bit of a slow start, but don't write it off. The first few days are small, but there's a real gem shaping up for the end of the month and into early September. The real standout window is from the 29th of August through to the 7th of September, with a few absolute crackers in there.

The pattern starts on Monday the 24th with tiny waves. Monday morning we're looking at a clean, glassy 2ft from the SW with a super long 18-second period. The combined energy is a moderate 345, and with the water sitting at a balmy 87°F – that's much warmer than normal for this time of year, a solid 4°F above average. It's a nice little session for a longboard or a foiler, but nothing to get too amped about. The afternoon gets messy with a cross-on wind, so morning sessions are the go.

Tuesday the 25th is more of the same – another 2ft SW groundswell with glassy conditions in the morning. It's consistent enough to get a few, but it's still small.

Now, Wednesday the 26th and Thursday the 27th are a bit of a write-off. The swell drops even further to 1ft and the wind is all over the shop. The energy is weak, and it's just not worth paddling out for.

But then, things change. Friday the 28th is a beauty. We've got a clean 2ft SW swell with a 20-second period. The morning is dead calm and glassy, and the afternoon stays glassy too. It's small, but the energy jumps to 346 in the morning and 397 in the arvo. Clean and fun.

The first true standout hits on Saturday the 29th. Saturday morning is looking prime. The swell bumps up to a clean 4ft from the SW, with a 16-second period, under dead calm, glassy skies. The combined wave energy is a solid 747. Expect very good, clean conditions. This is the one to circle on your calendar.

Sunday the 30th keeps the run going. Another morning of glassy 4ft from the SW (14-second period), with energy at 681. It's still very good.

Monday the 1st of September and Tuesday the 2nd keep the quality up. Monday morning has a glassy 3ft from the SW, and Wednesday morning the 3rd is dead calm with a clean 3ft. The consistency is there.

The next absolute standout is Friday the 4th of September. Friday morning brings a crisp, clear 4ft from the SW, 17-second period, with a massive combined energy of 955. Glassy winds. This is excellent, punchy groundswell for Cabo. The direction (SW) matches perfectly with the optimum for the break. It's a bit much for beginners, but for anyone with a bit of experience, this is the best of the bunch.

Saturday the 5th is nearly as good: a calm, glassy 4ft from the SW, with energy at 879. A touch bigger, but still very good.

We've got one more real beauty at the tail end. Monday the 7th of September has a glassy morning with a 4ft SW swell and a solid 14-second period. Energy is pumping at 870. Very good.

And then the real cherry on top for the experienced crew: Tuesday the 8th of September. The morning brings a clean 3ft SW groundswell with a very long 20-second period. The wind is a light cross-offshore, and the combined energy is a whopping 1089. That's serious energy. The long period will make for excellent, well-shaped waves at a point break like this, but the sets will be more spread out. This is expert territory – the power and size will be well overhead on the sets. For the skilled surfer, this is your session.

A word on crowds: Cabo Blanco can get busy, so be prepared to share the peak on those stand-out days.

The afternoons most days are plagued by onshore winds and the threat of storms, so stick to the morning glass-offs for the best of it.

Rusty, signing off.

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.
