The Lowdown
Alright, this is Rusty checking in with the outlook for your local stretch.
We've got a run of small, clean conditions coming up, but the real standout is going to be Saturday the 8th. That morning, Cabo Blanco is looking prime with a 4ft SW groundswell, glassy offshores, and a solid 653 (moderate-strong) combined energy. It's the best combo of size and clean conditions on offer.
The water temp is about average for this time of year, so nothing out of the ordinary there.
Right now, on Tuesday the 4th morning, there's already a little 3ft SSW swell with glassy conditions, so it's worth a paddle. The energy is moderate (251). The afternoon gets a bit onshore and messy, so make the most of the morning.
Wednesday the 5th is a write-off with cross-shore and onshore winds all day.
Thursday the 6th morning sees a drop in size to 1ft, but a long period 15-second SSW swell and a clean cross-offshore breeze make it interesting. Energy is moderate (202). Friday the 7th morning is back to glassy with a 2ft, 18-second groundswell (448 energy). That's a long period, so it'll be better for a point or reef setup.
Then Saturday the 8th morning is the pick of the week: 4ft SW, 16-second period, glassy, and 653 energy. That's the one to circle. Sunday the 9th and Monday the 10th mornings are also glassy with waist-high swell, consistent and clean.
The second week keeps a similar pattern. Thursday the 14th morning has a 2ft, 19-second SW groundswell, glassy, with 503 energy. That's a long period, clean swell. Then Saturday the 15th and Sunday the 16th mornings both show 3ft to 4ft SW groundswell with glassy conditions and strong energy (745 on Saturday, 546 on Sunday). Monday the 18th and Tuesday the 19th mornings also offer clean, glassy conditions with waist-high swell.
Overall, it's a solid run of small, clean mornings. Saturday the 8th is the standout, but keep an eye on Saturday the 15th and Sunday the 16th for similar quality.
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.
