The Lowdown

Alright, surfers, this is Rusty comin' at you. Let's get into it.

We've got two weeks of potential ahead at Cabo Blanco, and to be honest, the first few days look like they're gonna deliver the best of the run. The water is sitting at a warm 86°, which is a touch warmer than what we usually get at this time of year, so that's a nice little bonus for the early sessions.

Kicking off on Friday the 4th, it's a bit of a write-off with a risk of thunderstorms and a cross-onshore breeze chopping up a 4ft SW swell. You'll feel that moderate wave energy (993), but the wind's not doing us any favours, so it's a day for the die-hards only.

Now, hold onto your boards, because Saturday the 5th morning is where it's at. We've got glassy conditions, zero wind, and a solid 4ft groundswell rolling in from the SW with a long 16-second period. That's 863 (moderate energy) of clean, lined-up power coming straight into that exposed SW swell window. It's not huge, but it's gonna be gorgeous.

Sunday the 6th morning is another beauty. Glassy again, with the swell holding at 4ft from the SW, 15-second period and 685 (moderate energy). It's going to be clean and fun.

The rest of the first week and into the second week is a bit more of a mixed bag. We get a run of mornings with glassy conditions, but the swell drops a bit. Monday the 7th morning is glassy with 3ft SW swell (431), Tuesday the 8th morning is glassy with a smaller 2ft SSW groundswell (475), and Wednesday the 9th morning is glassy with 3ft SSW (518). The quality is there because of the wind, but the size is getting smaller. Afternoons are generally ruined by onshore breezes and thunderstorm risks.

Thursday the 10th and Friday the 11th mornings both look glassy again with 3ft and 3ft SW swell, respectively. Saturday the 12th morning is glassy with a dropping 3ft SW swell. The energy levels are dropping each day, from 597 down to 308. It's still surfable, but it's not the standout action of the first weekend.

There's a longer gap in quality after that. From Sunday the 13th right through to Friday the 18th, the mornings are mostly glassy, but the swell is small—between 2ft and 3ft. That Monday the 14th morning has a 3ft SSW swell, but the period is a short 7 seconds, so it's not going to have much punch. It's going to be a quiet week.

The final standout, if you're looking that far ahead, is Saturday the 19th morning. A tiny 2ft SW swell rolling in with a very long 20-second period and glassy conditions. It's a promise, not a guarantee this far out, but that kind of period usually means some clean, long lines at this spot if it fills in. Keep an eye on it.

Crowds are only listed as "sometimes" here, so you're not looking at a circus, thankfully.

Rusty out.

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.
