The Lowdown
Alright, this is Rusty comin' at ya from the shores of Cabo Blanco. Let's have a look at what the next couple of weeks are serving up.
We're kickin' things off with a bit of a slow start, but don't let that fool ya. The water is sitting at a warm 86°F with a touch warmer than normal anomaly, so it's gonna feel like a bath out there. The first few days are pretty small and mixed with some stormy weather, but the real juice doesn't start building until the second week.
For Friday the 31st, it's a write-off with that risk t-storm and onshore wind. Wait for Saturday the 1st. Saturday morning we get a glassy calm with a 3ft SW groundswell (13 seconds) rolling in. The energy is moderate (277), and it's gonna be clean. The best morning of this early stretch is Sunday the 2nd: another glassy morning, a 2ft SW swell, still a decent 12 second period. Clean, small, and fun for a log or a fish.
Now, the real standout is shaping up for Saturday the 8th of August. Saturday morning we get glassy conditions again, a solid 4ft SW swell pushing in with a 16-second period. The combined energy jumps up to a strong 660. This is a proper groundswell, and with that long period, it'll be lining up nicely at Cabo Blanco. The wave quality is top-notch. This is the one to circle on the calendar. The Saturday the 15th of August is also looking promising with a 3ft SW swell, a very long 17-second period, and glassy morning winds. Energy is 522. Another strong groundswell, but a touch smaller. Perfect for a point break.
Keep in mind, for the real beginners, that 4ft swell on the 8th is manageable, but anything over 5ft is where it gets a bit heavy. For the rest of the week, it's mostly small (2ft to 3ft) with that SSW direction, but the mornings are consistently glassy. The afternoons are a write-off thanks to the onshore breeze and storm chances. The crowd factor here is "sometimes", so you might have some company, but it's nothing like a circus.
Summary for the die-hards: The best waves are on the mornings of Saturday the 8th and Saturday the 15th. Both have clean, glassy conditions and strong, long-period SW groundswells. The 8th gets the edge for size. Long-range, so keep an eye on it, but it's looking tasty.

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.
