The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Cabo Blanco.
We’ve got a bit of a slow start this week, but if you’re patient, the second half of the outlook is where it’s at. The water is sitting at 87°F which is a touch warmer than normal for this time of year, so you can leave the thick wetsuit at home.
The first few days are a bit of a tease. Sunday morning the 19th has some waist-high 3ft groundswell from the SSW, but it’s a bit of a bumpy mess with a cross-shore wind. The energy is moderate (502), but it’s not gonna be a pretty ride. Monday morning the 20th cleans right up though – glassy conditions with a smaller 3ft SSW swell (413 energy). It’s small, but it’ll be clean and fun for a log or a mid-length. Tuesday morning the 21st offers similar 3ft S swell with a nice cross-offshore breeze, keeping it clean. Worth a paddle if you’re keen for a few.
Now, hold onto your board. The real standout is going to be Tuesday the 28th. Cabo Blanco is exposed to the SW, and we’ve got a solid 5ft SW groundswell rolling in with a long 18-second period. The energy is strong (1318), and the wind is glassy all morning and afternoon. This is excellent surf for experienced surfers – the waves will have real push and shape, but the sets will be more spaced out. It’s not a beginner wave at this size. This is the best session on offer.
There’s another promising run building up to that. The 24th and 25th of July have a very long period swell (20-24 seconds) with glassy to clean conditions, but the swell height is smaller (2ft-3ft). The energy is still strong (up to 642), and those long-period lines will wrap in nicely, but the size is modest. The 26th and 27th keep the good vibes going with consistent 3ft SW swell and clean/glassy mornings.
After the 28th, the swell slowly drops back down through the 29th into early August, but there are still some clean, glassy mornings for the smaller waves. The 31st morning and the 1st of August morning both look like fun, small, glassy sessions for the longboard.
Bottom line: Don’t stress about the first week. Wait for that Tuesday the 28th, and you’ll be rewarded with some of the best, cleanest, punchy waves of the whole forecast. The crowds are *sometimes* an issue here, so get out early.
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.
