The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking for this stretch.
Right off the bat, Tuesday the 28th of July is where it’s at. We’ve got a solid SW groundswell rolling in at 4ft with a long 18-second period, and the energy is pumping hard with a reading of (1097). The wind is glassy out of the ENE, so the morning session at Cabo Blanco is going to be absolutely clean. The water is sitting at 86°, which is a touch warmer than normal for this time of year, so it’s a real treat. This is the standout session of the whole outlook – excellent surf for experienced surfers, and the offshore direction is right on the money for the SW swell. It’s going to be a ripper of a morning.
After that, the swell holds up into Wednesday the 29th at 4ft, still SW but the period drops to 16 seconds. The energy is still strong (898). The morning is glassy with a calm wind, so it’ll be clean and fun, though the quality dips a little from the day before. By Thursday the 30th, the swell starts to ease to 4ft (498) and the period drops to 14 seconds, but the morning is still glassy out of the NW. It’s good, but not the peak.
From Friday the 31st of July right through to the first week of August, the swell drops off. We’re looking at 3ft down to 2ft waves, with periods mostly in the 12 to 13-second range. The energy falls into the 200s and 300s, so it’s weak. The mornings are often glassy, but the waves are small and ordinary. There’s a stretch of several days here where the surf is just not worth getting excited about – it’s a real lull.
Now, looking ahead to the second week, there’s a flicker of promise. Saturday the 8th of August, the morning has a 3ft SSW swell with a 16-second period. The energy jumps back up to 541, and the wind is glassy out of the WNW. That’s a promising session, but it’s a week and a half away, so keep your expectations in check. The periods are long, which is great for points and reefs, but at a beach break it might be a little straight. Still, it’s the best thing on the horizon after the first couple of days.
Overall, the real standout is Tuesday morning, the 28th of July. Get out there if you can. The rest of the run is small and average, with a few clean but weak mornings.
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.
