The Lowdown

Alright mates, Rusty here. Let’s break down this next stretch of the swell calendar, ’cause there’s a bit to unpack.

The ocean’s got some life in it to start, but don’t get too attached. It’s a story of one killer morning, a few small clean ones, a long flat spell, and a hopeful bump right at the end.

Saturday morning (Aug 15) is your golden ticket. We’re looking at a clean 4ft of SW swell, with a long 16-second period. That’s proper groundswell, and the combined energy is a strong 712. The wind is glassy, totally calm. This is the standout of the whole run. The water is a warm 87°, which is nearly 4° above the usual – that’s very unusual and will feel like a warm bath.

The afternoon ruins it a bit with a cross-on wind, so get your fill in the AM. Sunday morning (Aug 16) is still clean, with 3ft of swell, but the energy is a bit less. It’s still fun, but not as powerful.

From there, it’s a slow fade. The mornings mostly stay glassy, which is great, but the swell drops. Monday afternoon (Aug 17) has a window of glassy conditions at 3ft, and Tuesday (Aug 18) and Wednesday (Aug 19) have clean 2ft to 3ft waves. It’s log-able, but you’re working for it. The energy is coming down, from the 400s into the 300s.

Thursday (Aug 20) the swell turns a bit more south and the period drops to 10 seconds. It’s a different, less refined swell. Still clean in the morning, but you can feel the quality drop.

Then comes the lull. From around Friday (Aug 21) through the next week, it gets small. We’re talking 2ft to 3ft, but mostly in the 2ft range. The energy plummets into the low 200s and even down to the 100s in the middle of the week. It’s not dead flat, but it’s pretty pathetic. There are still glassy mornings, but the lack of size and energy makes it hard to get excited.

The period from about Sunday (Aug 23) through Thursday (Aug 28) is a real dead zone. The waves are small, weak, and just not worth the paddle. Even with some long periods (15-18 seconds), there’s no size behind them. It’s a time to do other things.

Now for the long-range hope. Saturday morning (Aug 29) , the energy meter jumps back up to a strong 648 with 3ft of SW swell at 15 seconds. That’s a huge change. And Sunday morning (Aug 30) looks even better, with energy hitting a very strong 751 and swell building to 4ft with a 15-second period. The wind is forecast to be calm, which is ideal. It’s a while away, so don’t get your hopes too high, but it has the makings of a proper return to form.

So, bottom line: hit it hard on Saturday morning. Then pick your spots on the small clean mornings. The middle of the week is a right-off. And keep an eye on that final weekend – it might just save us.

Rusty out.

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.
