The Lowdown
Alright, this is Rusty checkin' in from the local sand dune, lookin' at the charts for Cabo Blanco. We’ve got a solid run of surf ahead, so let’s dig in.
We're kickin' off right now with a beauty. Wednesday morning, July 29th, the ocean’s flat calm with glassy conditions. There's a solid, long-period SW groundswell rollin' in at 4ft, with a period of 16 seconds. That's a proper groundswell, and the water is a touch warmer than normal at 86°F. This is the standout of the whole forecast – a real special morning. The energy is strong, with combined swell energy of 898, and offshore NE winds make it clean as a whistle. This is the one to point the van at. Remember, that long period will make the sets a bit more spaced out, so paddle out before the lull. Crowds are possible here though, so get in early.
Thursday morning, the 30th, the swell backs off a hair to 4ft from the SW, period 14 seconds, with no wind – dead calm and glassy. It's a good session, but the energy is moderate (498). Friday morning through Sunday morning keeps the trend: clean, glassy mornings with waist-high sets around 2ft to 3ft. The energy drops each day, from 338 down to 244. Not the biggest, but the morning windows are all rideable.
We hit a bit of a lull from Monday, August 3rd, into Tuesday. Monday morning is tiny at 1ft, but glassy. The next real pulse shows up on Wednesday, August 5th, with a fresh SSW swell, but the period drops short to 9 seconds. It's glassy in the morning at 3ft, but the energy is lower (248) and the shorter period means less grunt.
Alright, now for the second week. We get a nice little spike on Friday, August 7th. Morning glass, 3ft from the SSW with a very long period of 18 seconds. Energy is strong at 576. That’s a promise of cleaner, longer walls – a good pick for the first week of August. Saturday, August 8th, builds a bit more: 4ft from the SSW, 16-second period, glassy morning winds. Energy is strong at 740. Another morning worth marking. The Sunday and Monday mornings after that are smaller, in the 2ft to 3ft range, glassy, but not the week's highlight.
Then on Tuesday the 11th, another standout pops up. Morning glass, 2ft from the SW, but with a very long 20-second period. The energy is strong again at 541. That’s a sneaky good session for a point break or a reef – those long-period waves will be super clean and walled up, but they might run a bit straight on a beach break.
So, to sum it up: the absolute best of the whole 16-day window is Wednesday morning, July 29th. If you can’t make that, the mornings of Friday August 7th, Saturday August 8th, and Tuesday August 11th are your next best bets. The rest of the mornings are clean but mellower. Afternoons are a write-off with onshore wind or storms, so stick to the dawn patrol.
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.
