The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Cabo Blanco over the next couple of weeks.

Overall, we’re looking at a pretty consistent run of small, clean surf. Nothing massive, but plenty of glassy mornings to get the log or a fish out. This is a long period groundswell scenario – those 16 to 18 second intervals mean proper lines rolling in, but the size stays modest, so it’ll be peeling nicely rather than closing out. Perfect for a cruiser session. The first real standout is Friday the 14th – that morning is where it’s at. We’ve got a 3ft SW groundswell (18 seconds) with absolute calm conditions, no wind at all. The combined energy pushes up to 678 (moderate) and it’s shaping up for a really tidy session. Water temp here feels about average for this time of year. Cabo Blanco is an exposed SW spot, so this direction is bang on, and while crowds are possible now and then, a weekday with this kind of glass should thin ‘em out a bit.

Leading up to that, it’s a bit of a mixed bag. Tuesday the 11th and Wednesday the 12th both have glassy, clean mornings with small 2–2ft SW swell, but those afternoons get ruined by onshore breezes and even some thunderstorms. The energy is weak to moderate (341–373) on those mornings, so it’s worth it if you can sneak out early. Thursday the 13th is similar – a clean 2ft SSW morning, but it turns messy by lunch.

After Friday’s peak, Saturday the 15th still has a great morning – 4ft SW, glassy, with 704 combined energy (moderate) – but the afternoon turns cross-on. Sunday the 16th onwards gets a bit messier with wind ruining quality; morning sessions on Monday the 17th are light cross-shore and only marginal. Then we have a bit of a lull in clean windows from Tuesday afternoon through the weekend.

The next clear standout after that first week is Wednesday the 19th morning. Calm, glassy, 4ft SSW swell at 11 seconds. Energy is 650 (moderate). That’s the biggest clean swell of the whole window, but it’s still more than manageable for most surfers. Not big enough to call it expert-only, but enough to get a proper drop in.

The rest of the second week – from Thursday the 20th through to Wednesday the 26th – follows a similar pattern: small, clean mornings (2ft to 3ft S/SW) with calm or near-calm winds, but those afternoons blow onshore or go glassy but with poor quality. The energy drops right off into the 200–300 range (weak) by the end of the run. Nothing that’ll blow your socks off, but if you’re flexible with your schedule, there’s a wave to be had almost every morning right through.

Bottom line: Friday the 14th morning and Wednesday the 19th morning are the pick of the bunch. Don’t sleep on ‘em.

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.
