The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.

Overall, we’ve got a solid run of surf coming up, especially for a spot that’s known for being fairly consistent. The water’s a touch warmer than normal for this time of year, sitting at 86°, which is a nice little bonus. The real standout is the Saturday morning, the 8th of August, at Cabo Blanco. We’re looking at a clean 4 ft of southwest groundswell rolling in with a 16-second period, which is long period and means proper energy. The combined energy is 656 (moderate wave energy), and with glassy, offshore wind from the northwest, it’s going to be smooth as butter. That’s the session to aim for.

The Saturday afternoon gets messy with a cross-on wind and a risk of thunderstorms, so get out early. Sunday morning the 9th is a bit choppy with cross-shore wind, and the swell drops a touch. Monday morning the 10th is glassy again with a small 2 ft SSW swell, but it’s a winner for a clean, fun session. Tuesday the 11th has a glassy morning, but the swell is down to 2 ft – though the period is a very long 18 seconds, so it’ll be a sneaky, powerful little wave. Wednesday the 12th and Thursday the 13th offer glassy mornings again, but the swell stays small.

Now, Friday the 14th of August – that morning is another standout. The swell picks back up to 3 ft from the southwest, period is a long 18 seconds, and combined energy hits 603 (moderate wave energy). Glassy conditions with zero wind. That’s going to be a gem. Saturday the 15th morning is also strong: 4 ft of long-period southwest swell, 712 combined energy, and glassy conditions. Another cracker.

From there, the pattern holds. Sunday the 16th, Monday the 17th, and Tuesday the 18th all have glassy mornings with good southwest swell in the 3 ft to 3 ft range and periods around 14-15 seconds. The energy stays moderate. Wednesday the 19th and Thursday the 20th are similar, though the swell backs off a bit. Friday the 21st has a shorter period swell (9 seconds) but still glassy in the morning, and the weekend of the 22nd and 23rd finishes with small, clean surf.

A quick note for the ends of the days: almost every afternoon gets a cross-on or onshore wind, and often a risk of thunderstorms, so the mornings are where it’s at. There’s no real gap – the surf is consistent through the whole period. The best of the best is that Saturday the 8th and Friday the 14th morning sessions, with Saturday the 15th close behind.

Keep it glassy, keep it early.

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.
