The Lowdown

Alright, folks, Rusty here. Let's get the lowdown on what's shaking out over the next couple of weeks. The main event is all about Cabo Blanco, with a pattern of some real sweet morning windows and afternoons that get a bit sloppy.

The coming days are a tale of two halves each day. The mornings are where it's at. We kick off Saturday the 22nd with a glassy 3.3ft swell from the south, period of 10 seconds, and there's a decent amount of energy in the water (367). It feels like the kind of session where you can find a little rhythm. The water temp is about average for this time of year, so no surprises there.

Sunday the 23rd morning is a similar story – glassy, 1.6ft from the southwest, but look at that period: 19 seconds! That's a proper long-period groundswell. The energy jumps nicely (418). This kind of swell will wrap into points and reefs cleanly, giving you longer rides and making the paddle out easier between sets.

The same pattern holds for Monday the 24th and Tuesday the 25th. Mornings are glassy with 1.6ft of swell from the southwest. The period stays long in the 16 to 18-second range, with energy in the 220-345 bracket. It won't be huge, but it’ll be clean and fun on a log or a mid-length.

Then we hit a bit of a flat spot in the middle of the week. Wednesday the 26th morning is still glassy with a 1.6ft, 15-second swell, but Wednesday afternoon the period drops to a pathetic 6 seconds and the energy drops right off (219). Thursday the 27th is more of the same with that short-period, weak junk. Friday the 28th morning looks messy with a cross-shore wind, and the afternoon gets choppy.

Now, here's the real standout. Strap in for Saturday the 29th of August. The morning session is absolute gold: glassy, 3.6ft of solid southwest swell at 16 seconds. The combined energy is pumping at a healthy 740. That’s proper wave power. This is the one to circle on the calendar. If I had to pick one day to go all-in, this is it.

Sunday the 30th morning is also very strong – a glassy 4.3ft of southwest swell at 15 seconds and massive energy at 727. Another epic morning, but watch the afternoon as that cross-onshore wind kicks in and the energy stays strong (925), but the conditions will become bumpy. The early bird gets the worm, or in this case, the cleanest barrels.

The following week, from Monday the 1st of September through to Saturday the 6th, the mornings keep delivering. Lots of glassy or near-calm conditions with swell holding around 2.9ft to 3.6ft and period staying in the 12 to 20-second range. The energy climbs back up, hitting 808 on Friday the 4th morning and 788 on Saturday the 5th morning. That Friday afternoon, the 4th, even looks solid with glassy 3.6ft and 861 energy. Don't sleep on that, it could be a cracker.

Overall, it's a solid run for Cabo Blanco. The mornings are consistently clean, and that Saturday the 29th and Friday the 4th are the true gems. Crowds are possible here at this spot, so paddle out early to get the best of it.

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.
