The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up for Cabo Blanco.
We’ve got a pretty solid run of surf stretching across the next couple of weeks. The overall pattern is persistent SW groundswell, nothing massive, but consistent with some lovely glassy mornings. The water’s sitting at 86°, which is a touch warmer than usual for this time of year, so you can leave the thick wetsuit at home.
Thursday morning the 6th kicks things off with clean 1ft of SSW groundswell, a long 15-second period, and dead glassy conditions. Wave energy is moderate at 202. It’s small but tidy. The afternoon gets a bit onshore and messy, so make the most of the morning.
Friday the 7th looks even better. Morning glass again, with 2ft SSW swell, period bumping to 18 seconds, and the combined energy jumps to 450. That’s proper groundswell quality, but those long periods mean the waves might run a bit straight on the beach – look for a point or reef setup if you can find one. The afternoon goes onshore.
Saturday the 8th is the first real standout. Saturday morning brings 4ft SW swell at 16 seconds, combined energy of 655, and glassy conditions. That’s the pick of the first week. It’s still a manageable size, clean, and full of potential. The afternoon looks risky with thunderstorms and onshore wind, so get out early.
Sunday the 9th through to Wednesday the 12th keep a similar theme: mornings are glassy or calm, with swell in the 2ft to 3ft range, periods between 13 and 18 seconds, and moderate wave energy. Afternoons tend to get blown out or show questionable tide conditions. The Tuesday morning the 11th is another clean one with 2ft SW swell and an 18-second period.
Thursday the 13th morning is flat calm with 2ft SSW swell – nice but nothing to write home about. The real second standout lands on Friday morning the 14th: 3ft SW swell, 18-second period, combined energy at 551, and dead calm winds. That’s a morning for a longboard or a fish, with silky conditions.
Saturday the 15th morning offers 4ft SW swell again, energy at 757, and glassy wind. Another top morning. Sunday the 16th morning is similar with 3ft SW swell and calm winds.
Into the second week, the pattern holds. Mornings stay clean, afternoons get stormy or onshore. Monday the 17th and Tuesday the 18th both have glassy starts with 3ft SW swell. Wednesday the 19th is calm and glassy with 3ft SSW swell. Thursday the 20th morning sees a jump to 3ft SSW swell at 16 seconds, energy at 568 – that’s a very good morning. Friday the 21st morning rounds it out with 3ft SSW swell at 14 seconds, also glassy.
Best on offer: Saturday morning the 8th and Friday morning the 14th. Both have clean glass, solid SW groundswell, and good energy. Crowds are possible at Cabo Blanco, especially on those mornings, so get there early.
If you’re a beginner, most of these swells are under 5ft so you’re fine. The 4ft days might feel a bit punchy but still manageable. For experts, the long-period swells on the 7th, 11th, and 14th will give you the most power.
No real gaps of flat days here – it’s a consistent run. Just stick to the mornings.
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.
