The Lowdown

Alright folks, Rusty here. Let's have a look at what's cookin' at Cabo Blanco.

We've got a solid run of surf on the way, starting from this morning, but don't expect it to be firing every session. The pattern shows a classic, long-period SW groundswell pushing through, with that energy bouncing around all week. The water temp is sittin' right about average for this time of year, so no surprises there: just a regular wetsuit or a springy if you're used to the tropics.

This morning, Wednesday the 16th, is a real standout. Glassy conditions, no wind at all, and a clean 3ft SSW groundswell with a 16-second period. That 533 combined energy reading (moderate) packs a punch for the size. It's going to be smooth, clean, and have some real push behind it. Crowds are a possibility here, but with conditions this good, it's worth the company.

The glass holds for Thursday morning the 17th as well, with a similar 3ft SW swell and a 14-second period (458 energy). Another beautiful morning session if you can sneak away.

Things get a bit choppier through the afternoons with those cross-on trades and storm risks, but the mornings keep delivering. Sunday the 20th is another one to circle – glassy again in the AM with a long 19-second period SW swell at 2ft, but the energy is pumping at 509. That's a deceivingly powerful little wave.

Then Monday the 21st morning, glassy and clean with an 18-second period SW swell at 3ft. The energy is 545, which is the highest we'll see for that size. That's a beautiful, clean, long-period wave for Cabo.

As we push into the second week, the swell gets a bit more mixed. Wednesday the 23rd morning is all glass with a 5ft SW swell, but the period drops to 7 seconds – that's a short-period windswell, making it a bit bouncy and less organized. The energy is still decent at 402, but it won't have the same grunt as the longer period stuff.

After that, a bigger pulse of SW swell rolls in on Thursday the 24th, hitting 8ft, but that's paired with a strong, choppy cross-onshore wind (20 km/h / 12 mph). That's a messy, blown-out day for paddle surfing – honestly, that setup looks more interesting for the kite crew than us. It also gets up to 6ft on the 23rd afternoon, but with onshore wind, it's not the same story.

Towards the end of the run, Tuesday the 29th morning shows some promise again: a clean, 3ft SSW swell with a cross-offshore breeze (15 km/h / 9 mph from NNW) and 447 energy. It's not the biggest, but it'll be clean and rideable.

The Standout: Without a doubt, Wednesday morning the 16th is your best bet. That glassy start with a long-period SSW groundswell is the cleanest, most powerful wave for the size all forecast. Monday morning the 21st is the other one to get amped for – glassy and pumping with that 18-second groundswell. Both are proper long-period swells, so keep that in mind: they'll be a bit more lined up and offer longer waits between sets, perfect for a mellow paddle out.

Signing off, 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.
