The Lowdown
Alright, folks. Rusty here, giving you the lowdown on Cabo Blanco. We’ve got a mix of clean windows and afternoon stormy slop, but there are some definite sessions to get excited about.
Right now, the water is a warm 87°, which is much warmer than usual for this time of year – feels like a bath out there.
The real action kicks off on Friday morning, the 17th. It’s an absolute gem. We’re looking at a clean 4ft of SSW swell, with a 12-second period, and the wind is dead calm – glassy. The combined energy is moderate at 466. That’s the kind of start to the day you wait for. It’s clean, it’s there, and the crowds are only sometimes a problem, so you might have it to yourself for a bit.
Saturday morning, the 18th, is another standout. The swell is holding steady at 4ft from the SSW, period still 13 seconds, and again, glassy calm. The energy is bumped up to 503. This is a very good surf window. Take it, because the afternoons are a write-off with those stormy WSW winds coming in.
The pick of the whole run, though, looks like Tuesday morning, the 28th of July. The swell is a solid 4ft from the SW, with a long 18-second period. The combined energy is a massive 1307 – that’s strong wave energy. It’s a glassy morning with clean conditions. This is prime for the point break setup here, and the forecast says it’s excellent for experienced surfers. For the average surfer, this is a must-call morning.
There’s a bit of a gap after the first week, but the morning of the 29th is also worth a mention, with a clean 4ft from the SW and a 16-second period, though the energy drops back to 692. The 30th and 31st see the swell winding down, but mornings stay glassy, offering small, clean waves in the 2ft to 3ft range.
The long-range stuff on the 24th and 25th of July is promising but less certain. The numbers show a very long 24-second period, but the swell height is tiny at 2ft. It’s groundswell, so it’ll have that long, lined-up shape, but size is a question mark. Keep an eye on it.
Stay stoked, and I’ll see you out there.

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.
