The Lowdown

Alright, let’s look at what Cabo Blanco’s got cookin’ over the next couple of weeks, in feet and fahrenheit.

Right off the bat, Tuesday the 15th is a bit of a tease. We’ve got a tiny 2ft SW groundswell rollin’ in with a very long 18-second period, and the morning is glassy – dead calm. The water’s sittin’ at 86°, which is much warmer than normal for this time of year, so you won’t need a thick wetsuit. That weak combined swell energy (368) means it’s not gonna be pumping, but those conditions will be clean as a whistle. It’s a gentle start.

Wednesday the 16th is where it starts to get interesting. The morning brings a bit more size – 3ft from the SSW – still with that lovely long period (16s) and glassy conditions off an ENE breeze. The energy’s tickin’ up (535). This is really good, clean surf for a point break like this. The afternoon stays clean too, with the wind goin’ calm and glassy.

Thursday the 17th morning keeps the 3ft SW swell goin’ with glassy conditions again – another beauty. But watch out: by the afternoon, the wind swings cross-onshore and it gets messy.

Friday the 18th and Saturday the 19th are a bit of a write-off. The swell drops right down to 1ft, and even though the period is super long on Saturday (21 seconds), the wind is onshore and the energy is weak. Not worth paddlin’ out for.

Now, here’s the standout. Sunday the 20th morning: 2ft of SW groundswell with a 19-second period and glassy conditions. The energy is ramping up nicely (518), and the wind is slight – it’s gonna be silky. This is the best clean window of the first week.

Monday the 21st morning is another gem. 3ft SW swell, 18-second period, dead calm (glass). Energy is solid (577). This is a beautiful, long-period groundswell, and at Cabo Blanco – an exposed point break – that long period will wrap in perfectly and give you some proper lines. This is the pick of the first week, no doubt.

We then hit a big gap. From Tuesday the 22nd afternoon through to Thursday the 24th, the wind turns onshore, the swell gets short-period junk, and conditions are poor. There’s a little window Tuesday morning (22nd) with 3ft and glass, but it’s nothin’ special.

Friday the 25th morning is a wild card. We see 6ft from the WSW with a short 8-second period. The wind is glassy, so the surface will be clean, but that short period is gonna be a bit lumpy and fat. Energy is strong (524). This is solid size – maybe a bit much for beginners, but for the experienced crew at Cabo Blanco, it’ll be fun, though a little soft.

After that, it’s pretty quiet through the end of the month. There’s a bit of 3ft SW on Sunday the 27th morning, but it’s cross-shore wind and not really worth the paddle. The best of the second week is the Friday the 25th morning, but conditions are uncertain that far out – so keep your eye on it.

Overall, the real standout is Monday 21st morning – that 3ft SW groundswell with glassy wind and solid energy is gonna be clean, consistent, and a joy to surf. Sunday 20th morning is a close second. The water is well above average for the season, so ditch the thick rubber. Crowds are possible here – if you see the lineup full, just enjoy the clean shoulders.

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.
