The Lowdown
Alright, Rusty here. Let's have a look at what's coming our way.
We've got a decent run of small but clean surf on the cards for Cabo Blanco, starting this Sunday morning. The water is sitting at a balmy 86°, which is much warmer than normal for this time of year – a good 4° above average, so you can leave the wetsuit at home.
Sunday the 13th kicks things off with a clean 2ft swell from the SW, with a nice 13-second period. The wind is glassy, making for some really fun, clean conditions on the small waves. The combined energy is a modest 260 (moderate wave energy), so nothing thumping, but it’ll be a good one for a longboard or a funboard. Expect crowds to be around sometimes, as this spot is fairly consistent.
Monday morning the 14th looks similar, with the swell bumping up just a touch to 3ft from the SSW, period dropping to 9 seconds. Again, glassy conditions. That’s a solid morning session.
Tuesday the 15th brings a shift. The swell drops back to 2ft from the SW, but the period stretches out to 18 seconds. That’s a long-period groundswell, and with a cross-offshore breeze, it’ll be clean. The energy picks up to 392 (moderate wave energy). This is a standout for the week – that long period will make the most of the small height, especially on the point.
Wednesday morning the 16th is a real highlight. The swell is 3ft from the SSW with a 16-second period, and it’s glassy. The combined energy jumps to 550 (moderate wave energy), and the forecast says “expect very good surf conditions.” This is the pick of the first week. Get in the water.
The pattern continues through the end of the week and into the next, with small but clean swells, mostly in the 2ft to 3ft range, with plenty of glassy mornings. The period stays in the 13-16 second range, keeping the quality up.
Looking further out, Saturday the 26th shows a slightly bigger pulse. The swell is 5ft from the WSW, but the period is a short 7 seconds. That’s a wind swell, and while it’s bigger, it won’t have the same shape as the groundswells. The energy is up at 429 (moderate wave energy). It’s a good option if you want a little more push, but don’t expect the same long lines.
A notable mention for Monday the 21st: another “very good” morning with 3ft from the SW, an 18-second period, and dead calm wind. That’s a second standout session.
Overall, Cabo Blanco is offering a solid two-week block of small but clean, rideable surf. The real gems are the Wednesday 16th and Monday 21st mornings.
Stay stoked.

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.
