The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

We’ve got a solid run of surf coming our way, though it’s not going to be firing every single day. The pattern starts with a nice little pulse of long-period groundswell rolling in, and the standout window is looking like the early mornings. The water here is sitting at 86°, which is a touch warmer than normal for this time of year – you’ll be happy in a spring suit, maybe even just boardshorts if you’re tough.

The best bet for a proper session is Wednesday the 9th morning at Cabo Blanco. We’ve got a clean 3 ft swell from the SSW, but the period is a meaty 16 seconds – that’s proper groundswell energy pushing through, with combined swell energy at a moderate 518. The wind is glassy, dead calm out of the west at just 3 mph. That means clean, lined-up waves. Because the swell is long-period, it’ll wrap and hold its shape well here, and it’s an exposed spot so it’ll catch everything. It’s small but clean as a whistle. Crowds are sometimes an issue here, so get in early.

Come Wednesday afternoon, the wind swings onshore with a risk of thunderstorms, and the quality drops right off, so that morning window is the one to chase.

Thursday the 10th is a write-off. The wind stays cross-onshore and the morning is only marginal with a 3 ft SW groundswell. Not worth paddling out.

Friday the 11th morning is another cracker. Another 3 ft SW groundswell at 16 seconds, combined energy at 567, and glassy conditions again with a light NNE breeze at 3 mph. This is almost a repeat of Wednesday morning – clean, lined-up, and proper. If you missed Wednesday, this is your next go-to.

Saturday the 12th and Sunday the 13th see the swell easing back a touch, to 3 ft and 2 ft, but with glassy mornings and a bit of long period still in the water. Still fun waves, just not as punchy.

There’s a bit of a lull in the middle of the week, with smaller swell and afternoon onshores ruining the quality. Monday the 16th morning though, we get a nice spike: 3 ft from the SSW, 16-second period, combined energy up to 542, and flat calm, glassy conditions. That’s a solid session to mark on the calendar.

After that, the second week gets a bit more inconsistent. There’s another pulse of energy around Monday the 21st morning – 3 ft from the SW, 18-second period, combined energy of 535, and glassy wind. That’s a promising, long-period swell that will wrap nicely, though it’s still a long way out so keep an eye on it.

Thursday the 24th afternoon ends the forecast with a bit of a wildcard: the swell jumps to 5 ft from the SW, but the period is only 6 seconds – that’s a short, weak windswell. Winds are calm and glassy though, so it might offer some fat, crumbly waves for a longboard, but don’t expect anything with punch.

Overall, we’ve got a few gaps with poor afternoons, but the mornings are where it’s at. There’s enough consistent, clean swell to keep you busy through the first week especially. No massive swell here, just good, clean, long-period waves for those who make the early call.

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.
