The Lowdown

Alright, this is Rusty checking in with a look at what's coming up for Cabo Blanco. We've got a proper run of swell on the cards, but you'll need to pick your moments with the afternoon storms and wind.

The pattern for the next couple of weeks is a solid, consistent pulse of Southwest groundswell. The energy is moderate to strong – we're talking numbers in the 400 to 600 range for the combined energy, which means there's plenty of push in the water. The water’s a touch warmer than normal for this time of year, sitting around 86°, which is always nice for a longer session.

We kick off on Sunday the 6th, but it's a write-off with cross-on winds and a risk of thunderstorms. Surf’s about 4 ft but messy. The real start is Monday morning, September 7th. Get up early. The wind will be light and cross-off from the North, cleaning up a 3 ft Southwest swell. It’s not huge, but it’ll be clean and fun for a grovel.

Tuesday the 8th has a bit of a letdown in size with 2 ft, but then things get interesting. Thursday morning, September 10th, is a standout. We’ve got glassy conditions, a 3 ft Southwest swell from the optimum direction, and the combined energy is pumping at 587. That’s the pick of the first week – super clean, long lines likely.

Friday morning, September 11th, is another cracker. Dead calm, glassy, 3 ft Southwest swell with 528 combined energy. It doesn't get much better for a clean, user-friendly wave.

There’s a bit of a lull from the 12th to the 14th, with smaller swell in the 2 ft to 3 ft range, though the 14th has a short-period S swell at 3 ft that could be fun if you've got a fish. The glassy mornings on the 13th and 14th are worth a look for the peace and quiet.

Then the second week looks promising again. Wednesday morning, September 16th is a real gem on the long-range. Glassy conditions again with a 3 ft Southwest swell, 525 combined energy, and the wind is light from the East. That’s a solid session for a mid-week dawn patrol.

The weekend of the 20th and Monday the 21st also finish strong. The 21st has a great-looking morning: glassy, 2 ft Southwest swell but with a very clean 507 energy reading. That’s clean, punchy, and consistent.

Keep in mind that most afternoons here get a risk of thunderstorms and the wind swings onshore from the SW, so the mornings are definitely the window. Because of the afternoon wind, this spot won't be too crowded on the early sessions, though it can get busy at times. For the standout mornings I mentioned – especially the 10th, 11th, 16th, and 21st – the wind and swell direction are lining up perfectly for a proper session at Cabo Blanco.

Stay stoked, and I’ll see you in the water.

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.
