The Lowdown

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

We’ve got a solid run of SW groundswell on the way, and the secret here is the wind. For the most part, it’s looking light and often glassy, especially in the mornings. The water’s sitting at 87° – that’s much warmer than usual for this time of year, so you can leave the thick winter rubber at home. The swell energy is moderate, hovering around the 400-500 mark, which means there’s decent push without it getting out of control.

The real standout is coming up on Saturday, 29th August. The afternoon session looks like a cracker: clean 0.9m (about 3 ft) of SSW groundswell (period 16s), combined energy of 533, and glassy conditions. That’s a proper long-period groundswell hitting an exposed SW break – it’ll wrap in with shape and power. This is the pick of the whole forecast. The Sunday after that still looks good too, with clean 0.9m (3 ft) SSW swell and light winds. Crowds can be an issue here sometimes, so get in early.

For a closer-to-home call, Tuesday morning, 18th August is worth paddling out for. It’s glassy, with a 0.9m (3 ft) SW swell from a solid 14-second period. Combined energy is 442. That’s clean and fun, with no wind to mess it up. The Thursday after that, 20th August, shows a bump in size – 1.0m (about 3 ft) SSW in the morning with glass – but the period drops to 10 seconds, so it’ll be a bit less lined up.

There’s a noticeable dip in swell around the 23rd to the 27th, where we drop to 0.5m (2 ft) or lower. The energy drops way down too, with combined numbers in the 100-200 range. That’s a proper lull, but there are still some glassy mornings if you just want a longboard and some peace. The break is fairly consistent, so this quiet spell shouldn’t last forever.

From Friday, 28th August morning, the swell picks back up with a clean 0.6m (2 ft) SW groundswell, then builds into that cracker Saturday. The 31st August keeps the 0.9m (3 ft) SW rolling in, with a glassy morning – a solid way to end the outlook.

Keep an eye on the tides for Cabo Blanco, and remember: that long-period groundswell on the 29th is a point-style setup here, so it’ll hold its shape better than a beach break would.

Stay stoked.

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.
