The Lowdown

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

We’ve got a solid run of surf ahead at Cabo Blanco. The opening window kicks off with a lovely blend of clean, glassy conditions and a consistent, moderate South-West swell. The water is sitting at 86°, which is a touch warmer than normal for this time of year, so you can leave the thick rubber at home.

The standout of the whole forecast is without a doubt Thursday morning, September 3rd. The ocean is looking slick with a glassy surface and a light westerly breeze. We’re looking at 3 ft of swell from the SSW with a 12-second period, which will give you some nice, rideable lines. The combined energy is solid (542), and with the wind dead calm, it’s going to be clean and inviting. A real treat to start the period.

The pattern continues into Friday morning, September 4th, with another glassy morning. The swell has bumped up a touch to 4 ft from the SW, and the period has stretched to a very long 17 seconds. This is proper groundswell energy. The combined energy is up to 926, so there’s a lot of push behind those waves. That long period will mean long waits between sets, but the shape should be excellent, especially since Cabo Blanco is exposed to this direction. This is arguably the best quality wave of the whole window.

The weekends are looking promising too. Saturday morning, September 5th, is flat calm again with a 4 ft SW swell and a 16-second period. The energy is strong (884). Sunday morning, September 6th, is also glassy, with 4 ft of SW swell at 15 seconds. The energy is still very solid (671). These mornings are the pick of the days, with the afternoons being a bit of a write-off due to onshore breezes and storm risk.

The swell level will slowly drop through the following week, but the mornings remain the key. Monday, September 7th, and Tuesday, September 8th still offer glassy starts with a good 3 ft and 2 ft of swell respectively, though the energy dips a bit.

There’s a bit of a lull in the middle of the second week, with the swell getting smaller, but the quality remains if you’re picky. The mornings of the 13th and 14th offer clean, small surf.

Then, hold on to your board. The final real standout is Thursday morning, September 17th. We’ve got a tiny 2 ft of swell, but look at that period – 24 seconds. That’s an incredibly long period groundswell. The combined energy jumps back up to 542, and the wind is a light cross-off. This is a sneaky, super clean day that will produce some beautifully shaped, if inconsistent, waves. It’s a promise for the long-range, but it’s one to watch.

Overall, get on it early in the mornings. So many glassy starts and a solid, consistent SW groundswell. The best days are the 3rd, 4th, 5th, 6th, and that long-shot on the 17th.

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.
