The Lowdown

Alright folks, Rusty here. Let’s break it down.

We’ve got a solid run of surf coming up at Cabo Blanco. The water is sitting at a warm 87°, which is a good couple of degrees warmer than usual for this time of year – feels like bathwater out there.

The real standout is Thursday morning, August 27th. That’s the one to circle on the calendar. We’re looking at a clean 3 ft groundswell out of the SW, with a long period of 17 seconds pushing a moderate wave energy of 510. The wind is glassy, coming light from the ESE, so expect clean, lined-up walls. That’s a proper session.

Before that, there’s plenty of fun to be had. Wednesday morning the 12th kicks things off with a 2 ft SW groundswell at 16 seconds, glassy conditions, and moderate energy (376). The water is much warmer than normal, so a shorty might be overkill. Friday morning the 14th is another beauty – 3 ft SW swell, 18-second period, and strong energy (668) with flat calm, glassy conditions. Sunday morning the 16th is also worth a paddle, with 3 ft SW swell at 15 seconds and moderate energy (623), glassy again.

The afternoons are a write-off, though – risk of thunderstorms and onshore winds chop things up. The mornings are the key.

Further out, the 27th Thursday morning is the big one – 3 ft SW groundswell, 17 seconds, and strong energy (510) with glassy winds. That’s your best bet for the whole forecast.

A few other mornings like Wednesday the 19th and Friday the 21st offer smaller but clean windows. The 22nd Saturday morning shows 3 ft S swell, 10-second period, and moderate energy (243) with glassy conditions, but it’s a shorter period, so the waves might be a bit more crumbly. Still fun.

From the 23rd into the 26th, the swell dips a little, but there are still clean, glassy mornings with some long-period groundswell rolling in. The 27th is the real highlight.

Overall, get out there on the glassy mornings, and you’ll score. The 27th is the top 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.
