Alright folks, Rusty here. Let’s talk about what’s cooking for the next couple of weeks at Cabo Blanco.
We’ve got a solid run of surf ahead, starting this Friday morning, July 10th. The pattern is built around a consistent, long-period SSW groundswell that hangs around for days. The water temp is sitting at a very warm 87°F, which is much warmer than normal for this time of year – you won’t need much more than a spring suit, if that.
The standout window kicks off Friday morning. Cabo Blanco gets a clean 3ft SSW swell, with a long period of 15 seconds, and the wind is dead calm – glassy conditions. The combined energy is moderate at (583), and this is the kind of session you paddle out for before the afternoon seabreezes mess with it. The swell direction is right in the sweet spot for this exposed SW-facing spot. Expect clean, lined-up waves with those long gaps between sets making it easier to get out back. Watch out for crowds though – this spot can get busy, especially when it’s this good.
Saturday morning, July 11th, looks even better. Swell bumps up to 4ft from the SSW, period stretches to 16 seconds, and again we have glassy conditions with a light NW breeze. Energy is strong at (784). This is the pick of the weekend.
Through the following week, the mornings remain your best bet. Tuesday the 14th, Wednesday the 15th, and Thursday the 16th all show clean early conditions with 4ft to 4ft SSW swell and light or calm winds. The afternoons consistently turn cross-onshore or onshore, which kills the quality, so it’s a dawn patrol kind of setup.
Looking deeper into the run, Wednesday morning, July 22nd, shows a real jump in size – 5ft SSW swell, period of 14 seconds, and dead calm winds. The combined energy reads a solid (891) – that’s strong, powerful stuff. For the experienced crew, this is going to be a ripper, but it’s pushing into the realm where beginners should give it a miss. Too much power for a learner session.
Friday the 24th and Saturday the 25th are worth a mention too. Saturday morning the 25th has 4ft S swell, glassy conditions, and energy climbing to (586) – another solid early session.
If you’re looking for the total standouts, lock in Saturday the 11th and Wednesday the 22nd for the best quality and size, but remember the later date is more of a promising call – things can shift by then. For the rest, the mornings are your golden hours all the way through. Afternoons are mostly a write-off.
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.
