The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.
We’ve got one spot doing all the talking, and that’s Cabo Blanco. It’s a fairly consistent, exposed setup that likes a good SW push. The water is a touch warmer than normal for this time of year at 30°, so that’s a nice little bonus.
Don’t bother paddling out on Wednesday the 5th – it’s a write-off with a cross-on breeze and poor conditions. You’ll be waiting until Thursday morning the 6th for the first real sign of life. It’s small, only 1ft, but the glassy conditions make it worth a look for the longboard or a SUP. The swell is a long-period 15s groundswell, so there’s energy in the water even if it’s not pushy. The combined energy sits at 202 (moderate), and the glassy morning will be clean.
The standout window kicks off Friday the 7th. That morning, with 2ft of 18s SSW groundswell – that’s a very long period, so it’s going to pour in with real power. The combined energy jumps to 450 (moderate to strong). Glassy offshore wind from the east. It’s small, but those long lines will be wrapping in beautifully. This is the pick of the first week for a clean, lined-up session.
Saturday morning the 8th keeps it rolling with 4ft of SW swell at 16s, combined energy hitting 653 (strong), and glassy conditions. That’s your classic morning glass-off for a fun, punchy wave. The afternoon gets choppy and messy with a cross-on, so get it early.
The next absolute standout is Thursday morning the 14th. Glassy, calm, with 3ft of 18s SW groundswell and a combined energy of 581 (strong). That’s a proper groundswell pulse, and with the clean conditions, you’ll be getting some of the best shaped waves of the whole run.
Then Saturday morning the 15th delivers another gem: 4ft of SW groundswell at 16s, combined energy of 753 (strong), and completely glassy. That’s a powerful, clean session. The swell is just under 5ft, so it’s still manageable for most, but there’s plenty of grunt.
Later in the second week, on Thursday the 20th, we see a slight bump in size to 4ft, SSW at 16s, with glassy conditions and a combined energy of 695 (strong). It’s promising, but being that far out, keep your expectations in check.
The long-period swells (15-18s) here are prime for Cabo Blanco’s point/reef setup, so those waves will bend in with shape and power, not just close out. Great for the paddling, too – longer gaps between sets mean you can get into position without a fight.
The best on offer is the Friday 7th morning session for the pure, glassy, long-period goodness, and the Saturday 15th morning for a bit more size and power. Get out there.
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.
