The Lowdown

Alright, Rusty here. Let’s have a look at what’s coming our way.

We’ve got a classic setup building for Cabo Blanco. The water is at 86.7°F right now, which is much warmer than normal for this time of year – you’ll be surfing in a bath. The swell is coming in from the south-west, and with that long period, we’re talking proper groundswell that’ll wrap in nicely. The week starts a bit slow, but the real action kicks off later.

On Tuesday, August 13th the morning is glassy with a clean 2.3ft SSW swell. The energy is moderate (314) and the wind is dead calm. It’s a nice little window to get wet, but the swell is small.

Friday, August 16th is where we start to get excited. The morning has a 3ft SW swell, period a solid 18 seconds, and the combined energy jumps to 761 – that’s moderate energy but with significant punch for a wave that size. The wind is glassy out of the WNW. This is a standout. The waves will be clean, the sets will have some push, and the long period means it’ll be a joy to paddle out. Crowds are possible here, so get in early.

The following Saturday morning, August 17th sees the swell holding at 3.6ft from the SW with a period of 16 seconds. The energy is strong (707), but the wind is a light cross-onshore, so it’s not as perfect as the Friday. Still, there’s wave to be had.

The entire second week settles into a pattern of smaller, glassy mornings, especially on August 20th, August 22nd, August 24th, and August 26th – all showing clean conditions with swell around 2ft to 2.6ft, and gentle winds. The standout in the second week is the Thursday morning, August 22nd – a 3.3ft S swell, period a short 10 seconds, but with the wind glassy and calm. For a small day, it’ll be clean and fun. That’s your best bet for the tail end.

Honestly, you’ll want to mark your calendar for Friday, August 16th and Friday, August 23rd mornings. The 16th takes the crown – best size, best energy, cleanest conditions. It’s a proper session.

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.
