The Lowdown
Listen up, crew. Rusty here, talking about what’s cookin’ at Cabo Blanco.
We got a nice run of swell on the way. The first few days are looking prime, with clean glass and a consistent SW groundswell. Water temps are normal for this time of year, nothing weird.
The absolute standout is Wednesday morning, September 2nd. Cabo Blanco is seeing a 3ft SSW swell at 13 seconds. The wind is glassy, dead calm out of the east at 3 mph. It’s gonna be silky. The combined energy is moderate at 389, but the quality will be high.
Then Thursday morning, September 3rd is another banger. Swell at 3ft from the SSW, 12 seconds, and absolutely zero wind – dead calm. That’s smooth as glass. Energy is up to 542, which is solid.
Friday and Saturday mornings are both heaters. Friday morning, September 4th brings 4ft of SW swell at 17 seconds – that’s real long-period groundswell. Glassy again. Energy jumps to 926, which is getting strong. That long period will give it some serious push and shape, perfect for this point break, but you’ll have longer waits between sets.
Saturday morning, September 5th is another beauty – 4ft SW swell, 16 seconds, with just a faint breeze from the SSW. Energy is 864. Strong and clean.
Sunday, the 6th, holds up with 4ft SW and glassy conditions all day. That pattern of clean mornings runs right through to Tuesday, September 8th, with waist-chest high SW swell and glassy conditions.
After the first week, the size drops. From September 12th onward, we’re looking at smaller 2ft to 3ft SW swells, but the mornings stay mostly clean. The energy drops to the 200-400 range – weak to moderate. Still surfable, just not as powerful. Sunday morning, September 13th is worth a look with 2ft of SW swell and clean cross-offshore wind from the ESE at 6 mph.
If you want a session in the second week, hit Monday morning, September 14th. It’s only 2ft, but the period is a very long 18 seconds and the wind is clean cross-off. Energy is 334 – not much punch, but the lines will be long and easy. Also, Tuesday morning, September 15th is dead calm and glassy with that same long 18-second period. Tiny but perfect.
So, the story is: first week is the winner. Get out early. Afternoons are mostly blown out and stormy. This spot can get a few people on those good mornings, so don’t sleep in.
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.
