Table - best surf conditions forecast for Cabo Blanco over the next 16 days.
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid window of surf coming up at Cabo Blanco, with a nice long-period SSW groundswell rolling in. The water is much warmer than normal for this time of year, sitting at 87°, a good 4° above average, so you can leave the thick wetsuit at home. The overall energy is strong (1091) on Wednesday morning, which is the standout session of the whole 16-day run.
Wednesday morning, the 8th of July, is the pick of the bunch. Swell is 5 ft from the SSW with a very long 16-second period, ideal for a point or reef set-up like Cabo Blanco. The wind is glassy, calm as can be. This is a proper session for experienced surfers with that amount of energy in the water. The early crowd might be thin, but it’s likely to get busy later.
The rest of Wednesday afternoon sees a risk of thunderstorms and a light onshore breeze, so it’s a bit of a write-off. Thursday morning the 9th is still worth a look with 4 ft SSW swell and glassy wind, but the energy drops to a moderate 655. That same pattern holds for Friday and Saturday mornings: clean, glassy conditions on 3 ft to 4 ft SSW swell with periods still over 15 seconds. The energy stays in the moderate range, but it’s quality surf.
Sunday the 12th morning is glassy again with 4 ft SSW swell, but the shorter 14-second period knocks some of the grunt out of it. The afternoons from here on get messy with cross-onshore winds and build-ups, so stick to the mornings. Monday the 13th and Tuesday the 14th keep the clean mornings going with 3 ft to 4 ft SSW swell, but the period is dropping to 13-14 seconds.
The second week of the outlook is a mixed bag. The swell sticks around in the 3 ft to 4 ft range, mostly from the SSW, with a few mornings of glassy to calm conditions. The 18th and 19th of July, Saturday and Sunday mornings, are the best of the second week: 4 ft to 4 ft SSW swell, glassy, and moderate energy (614 and 573). Standout quality, but not as powerful as the opening Wednesday.
From the 20th onward, the swell fades a bit. Tuesday the 21st morning has a clean 2 ft SSW swell, but the energy is low. Wednesday the 22nd morning picks up again to 3 ft SSW with glassy wind and moderate energy, a decent little pulse to end the run. Overall, the first few days are the clear winners, and the weekends in the second week offer solid, clean backup options.
Rusty out.

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.
