The Lowdown

Alright, let’s talk about what’s going on for our stretch of coast. The main spot to keep an eye on is Cabo Blanco. It’s got good exposure to the open ocean and is set to catch a solid run of south-west groundswells over the next couple of weeks. The water temperature is 86°F, which is a touch warmer than normal for this time of year, so you’ll be fine in boardshorts or a light spring suit.

The action starts on Saturday morning, the 29th of August. We’ve got a 4ft south-west swell rolling in with a 16-second period – that’s proper long-period groundswell that’ll wrap in nicely. The wind is glassy from the north-west at just 3 mph, so the surface will be clean as a mirror. The combined energy is moderate at 666, meaning there’s decent push behind the waves. This is going to be a real treat for the early session.

The standout morning across the whole forecast is definitely Sunday, the 30th of August. The swell picks up a touch to 4ft, still from the south-west, with a 14-second period. The wind is dead calm – zero mph from the west-southwest, glassy as glass. Combined energy is up to 738, which is solid moderate. This is the kind of morning you set an alarm for. Clean, lined-up waves, not too big, not too small – just right for a fun session.

Moving into the week, the mornings keep delivering. Monday the 31st has 3ft south-west swell and glassy conditions again. The energy drops a bit to 424, but it’s still good, clean surf. Tuesday the 1st of September is similar with 3ft, glassy winds, and moderate energy at 366. Wednesday the 2nd brings 3ft, but the period drops a little – still clean though.

Then on Friday the 4th of September, we get another pulse. The swell bumps back up to 4ft from the south-west, with a 17-second period. The wind is calm, glassy, and the combined energy jumps to 825 – that’s strong moderate energy. This is a very good morning, and it’s worth thinking about if you can sneak out.

The following Saturday the 5th maintains 4ft south-west swell with 16-second period and glassy conditions in the morning. Energy is 953, which is pushing into the strong range. That’s a lot of juice, and the waves will have some real push. The swell is still manageable for most intermediate surfers, but it’s getting a bit more serious.

From the 6th through the 12th of September, the mornings stay mostly good with waist-to-chest high waves, glassy conditions, and moderate energy. The pattern holds up well. The 7th, 8th, 9th, 10th, and 11th all have very good mornings with clean conditions and consistent south-west groundswell. The 12th of September is a bit smaller at 3ft, but still good.

The last few days, the 13th of September, see the swell dropping to 2ft in the morning, still glassy, but the energy is down to 235 – weak. The afternoon gets messy with cross-onshore wind and a 19-second period, but that’s not a good combo.

Overall, the best windows are Saturday 29th and Sunday 30th August mornings, and then Friday 4th September morning. If you can only get one session, make it Sunday the 30th. That’s the pick of the pack.

Stay stoked,
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.
