The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s shaping up for Cabo Blanco over the next couple of weeks.

We’ve got a solid run of surf coming our way, starting from Tuesday the 1st of September. The early action is a bit messy, but by Wednesday morning the 2nd it cleans right up. The overall pattern is a slow build in energy through the first week, with some absolutely glassy mornings to take advantage of. The water is sitting at 86°F, which is a touch warmer than normal for this time of year, so you’ll be comfortable in just boardshorts.

Cabo Blanco is our only spot in the game, and it’s a pretty consistent performer. It’s exposed to the southwest, which is exactly where most of the swell is coming from. The crowd factor is listed as “sometimes,” so you might have a few friends out, but it’s not a circus.

The first standout is going to be Thursday morning the 3rd of September. We’ve got a clean 3 ft swell from the SSW, with a period of 12 seconds, and the wind is absolutely glassy – calm, 0 mph. The combined wave energy is moderate (542), and it’s going to be clean, lined-up, and very user-friendly. This is a real sweet spot for anyone who can paddle.

Then, Friday morning the 4th of September steps it up a notch. The swell bumps to 4 ft from the SW, still with a solid 17-second period, and again, glassy conditions with the wind coming out of the ESE at just 3 mph. The energy is building (825), and these longer period waves will have some real push behind them. They’ll be peeling nicely along the point. For a morning session, this is the pick of the first week.

As we head into the second week, things start to taper off. The mornings from the 8th through the 10th still offer some clean, glassy windows with 2 ft to 3 ft swell and good period (15-18 seconds), but the energy is dropping. Still, a longboard or a funboard would be a great choice. By the 12th of September, the swell drops to 3 ft and the energy is weaker (282). The 14th has a tiny 1 ft swell with a very long 18-second period – that’s a real slow, rolling groundswell, best for a point break like this, but only if you’re on a log.

The real highlight for the whole window, the one to circle on your calendar, is Sunday morning the 6th of September. We’re looking at 5 ft of SSW swell, with a 15-second period, and it’s completely glassy – no wind at all. The energy is strong (820), and with the swell direction matching the optimum from the southwest, this is going to be the best, most powerful, and cleanest wave of the whole forecast. The surf will be too big for beginners, but for intermediate and above, it’s going to be pumping.

So, to sum it up: get on the Thursday the 3rd for the clean small stuff, but don’t miss the Sunday the 6th for the best size and quality. The second week is quieter, but still worth a paddle on the glassy 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.
