The Lowdown

Alright folks, Rusty here. Let’s get into it.

We’ve got a solid run of clean, glassy mornings on the cards at Cabo Blanco, starting Thursday the 10th of September. The water is sitting at a warm 86°, which is a touch warmer than normal for this time of year – you’ll feel that balmy bath water.

The pattern kicks off with a lovely, long-period SW groundswell – 15 seconds – but it’s only pushing 3 ft. The combined energy is moderate at 602. That’s not a lot of power, but with glassy conditions and a light WNW breeze, it’s going to be clean and fun for a log or a fish. The sets will be well-spaced.

Friday the 11th is a carbon copy of the morning: 3 ft, SW, 16-second period, glassy with a whisper of NW wind. The energy is still moderate (567). This is the pick of the early window. Mornings are the story here – afternoons get messy with a risk of thunderstorms and a cross-onshore wind.

The quality holds through the weekend. Saturday morning (12th) is dead calm, 3 ft SW, 14-second period, and glassy. Crowds are listed as “sometimes” at Cabo Blanco, so expect a few other heads out, but it won’t be a circus. Sunday morning (13th) is a bit smaller at 2 ft and 13 seconds, but still clean.

The real standout is Thursday the 24th of September. The morning brings a glassy 2 ft SW groundswell with a 14-second period, and the combined energy is strong at 545. It’s a clean, lined-up morning. But the afternoon? That’s when the swell jumps to 6 ft, SW, with a short 7-second period, and the energy rockets to 832 (strong). The wind is a cross-onshore, so it’ll be choppy, but that’s a lot of juice.

Friday the 25th of September is the big one. The morning is dead calm – glassy as can be – with a 6 ft SW swell. The period is short at 7 seconds, so it’s a windswell, but the energy is a massive 814 (strong). That’s too big for beginners, but for the crew on a step-up or a funboard, it’ll be a punchy, fun wave. The afternoon sees the swell hit 7 ft with 889 energy, but the wind goes onshore. That morning window on the 25th is the absolute best session on offer.

There’s a gap from the 20th to the 22nd where the wind is all cross-onshore or onshore, and the surf is just poor. Don’t bother. The 23rd morning has a quick uptick in size (5 ft) but a short period, and it’s glassy, so it’s worth a look if you’re keen.

Stay safe, keep it clean, and don’t fight the afternoon chop.

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.
