The Lowdown
Alright folks, Rusty here. Let’s get into it for Cabo Blanco. We’ve got a solid run of surf coming through, with the standout window shaping up around the end of July and into August. The water’s sitting about average for the time of year, so no crazy surprises there.
The first real action kicks off Tuesday morning, 21 July, with some clean 2ft groundswell from the SW, period a nice 14 seconds, and the wind is glassy out of the east at 3 mph. The combined energy is moderate (407). It’s a gentle start, but the surface is clean. Tuesday afternoon the wind switches cross-on and the quality drops, so get it while it’s good in the morning.
Wednesday morning, 22 July, is a bit messy with cross-shore wind, but Wednesday afternoon cleans right back up – glassy again, 3ft SSW swell, 12-second period, and a moderate energy reading (262). Thursday morning, 23 July, is small and glassy, but Thursday afternoon we see a jump: 1ft of swell but with a very long period of 26 seconds from the SW. That’s proper groundswell energy, and the combined energy is moderate (329). This kind of period will wrap nicely around the point, but it’ll be a bit fat on the beach. Good for the reef.
Now, Friday morning, 24 July, is looking promising. 2ft SSW swell, 24-second period, glassy wind from the SSE at 3 mph. The combined energy is strong (643). That’s a solid morning. The afternoon is a write-off with onshore wind.
Saturday morning, 25 July, is dead calm, glassy, 2ft SW swell with a 21-second period. Combined energy is strong (547). This is a real gem – clean, empty feeling, and the long period means the waves will have shape and power. Saturday afternoon gets cross-onshore again.
Sunday morning, 26 July, is another beauty: 3ft SW, 19-second period, glassy, and the energy is strong (670). The morning sessions are the clear winners here.
The real standout, though, is Tuesday morning, 28 July. Swell jumps to 5ft from the SW, 18-second period, and the wind is glassy out of the north at 3 mph. The combined energy is very strong (1213). This is the best of the bunch – clean, powerful, and for experienced surfers, it’s going to be firing. The afternoon gets onshore, so don’t sleep in.
Wednesday, 29 July, and Thursday, 30 July, mornings both offer 4ft SSW groundswell with 16 and 15-second periods respectively, glassy, and strong energy. Consistent, clean, and solid. Friday morning, 31 July, is similar at 5ft, 14 seconds, and glassy – strong energy (776).
Into August, Saturday morning, 1 August, is 4ft, 13 seconds, glassy, and good. Sunday morning, 2 August, is a bit smaller at 3ft. Monday morning, 3 August, is dead calm and 2ft. Then Tuesday morning, 4 August, delivers another solid 4ft, 12-second SSW swell, glassy, with very strong energy (759). And Wednesday morning, 5 August, caps it off: 5ft, 13 seconds, dead calm, glassy, and strong energy (738).
Overall, the morning windows are firing. The best of the lot is Tuesday 28 July morning – that 5ft SW groundswell with glassy conditions is the one to circle. The long-period swells mean the point will be peeling, and the reef will have proper shape. Crowds are possible at times, so get in early. Cabo Blanco is fairly consistent, so there’s plenty to go around.
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.
