The Lowdown

Alright crew, Rusty here. Let’s talk about what’s brewing for Cabo Blanco. It’s a quiet couple of weeks, with small windows of clean conditions, but you’ve got to be patient.

The first real chance to get wet comes Monday the 7th of September. The afternoon goes glassy with a tiny 3ft swell from the SW. It’s not going to blow your mind, but glassy water is a gift. The water is a warm 86°, which is a touch warmer than usual for this time of year.

The standout session, the one I’m circling on the calendar, is Thursday the 10th of September. The morning is looking perfect: clear skies, a glassy ocean, and a 3ft SW swell with moderate energy (597). It’s small, but it’s going to be clean and fun. The morning of the 11th of September also has glassy conditions with a 3ft SW swell, but the afternoon gets ruined by a 15 km/h cross-onshore wind.

If you’re planning ahead, the morning of Wednesday the 16th of September is another one to watch. Another glassy start with a 3ft SSW swell and very good energy (540). It’s a long way out, so take it with a grain of salt, but it looks promising.

The rest of the forecast is a whole lot of small, marginal surf. The swell never really gets above 4ft, and that 4ft on Saturday the 5th is a washout with onshore wind and thunderstorms. The swell is long-period (15-21 seconds), which is a classic groundswell that will wrap in nicely here, but the energy is low, so expect long lulls between sets.

The best bet is the glassy Thursday morning of the 10th. It’s not a big day, but it’ll be the cleanest. The 16th is a hopeful long shot.

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.
