The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Cabo Blanco over the next couple of weeks.
To be straight with you, this is a grim stretch. The entire 16-day window is almost completely flat or offering tiny, weak waves, and the wind is mostly cross or cross-shore in the moderate to fresh range. For a point break that needs a solid swell to work, this is a tough one to call. The water is absolutely roasting, sitting at 77°F, which is a massive 12°F warmer than normal for this time of year – that’s far warmer than usual, so don't expect a cold water session.
The first real chance at anything comes on Friday, September 5th, with a tiny bump of 0.3 ft from the NW, but it’s only 11 seconds period and the energy is pathetic (5). The wind is light and cross-shore, so at least it’s clean, but let’s be honest, it’s barely a ripple. The Saturday and Sunday following are even worse, with almost no swell. The energy readings are all in the single digits (4-9), and the winds stay cross or cross-onshore, so it’s not worth paddling out.
Honestly, the only period that might get your heart beating a little is around the middle of the second week. On Thursday, September 10th, we see a tiny bump in energy to 62 in the afternoon, with a 1 ft swell from the WNW at 11 seconds. That’s a long period for such a small wave, but it’s clean with light winds in the morning. Still, 1 ft isn’t breaking, not at a point like Cabo Blanco.
The best of a bad bunch looks to be around Friday, September 11th and Saturday, September 12th. The swell stays a meager 1 ft from the WNW at 11-12 seconds, with energy climbing to 65 in the afternoon on Friday. The wind is light and cross-shore in the morning, so you might get a tiny, clean little wave if you’re desperate. But 1 ft is not a surfable wave in any meaningful sense for a point break. The swell direction is from the WNW, which is not the optimum NNW, so it’s not hitting the spot well.
This is a bust, folks. The entire forecast is a zero. There is no standout day. The water is weirdly hot, the swell is absent, and the wind is mostly messy. For a point break that needs size and direction, this is a total shutout. I’d leave the board at home and go for a swim.

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.
