The Lowdown
Alright, folks. Rusty here. Let’s get into it. We’ve got a solid run of surf lining up along the coast here, with the main event hitting early next week. The pattern is a slowly easing long-period SW groundswell that’s already pulsing, with a fresh pulse of similar energy arriving around the 8th of August. Mornings are your ticket, with plenty of glassy conditions.
The pick of the first week is Tuesday morning, July 28th, at Cabo Blanco. We’re talking a solid 4ft SW groundswell with a very long 18-second period, packing a punch with strong wave energy (1097). The wind is a light ESE breeze, keeping things glassy. This is excellent, powerful surf, but that 4ft with that much period will have some grunt – it’s one for the experienced crew looking for a proper long-period ledge. The water temp is pretty average for this time of year, so no surprises there.
The next standout is a promising one, but it’s further out. On the morning of Saturday, August 8th, we’ll see another pulse of 4ft SSW swell, again with a long 16-second period, and moderate-to-strong energy (796). The wind is light from the WNW, keeping it glassy. This is a very good morning for the more experienced surfer. The break is fairly consistent, but be aware that it can get crowded at times, especially when the swell is good.
Through the rest of the period, the swell hangs around in the 2ft to 4ft range, mostly with clean, glassy mornings. The mornings of the 29th, 30th, 31st, 1st, and 2nd all offer clean, rideable surf for the mid-length. The combined energy drops from moderate to weak as we go, from 898 down to 283. The afternoons are generally a write-off with onshore winds. There’s a short drop in swell size and quality around the 5th and 6th of August, with small, short-period windswell, before the better pulse kicks back in for the weekend of the 8th and 9th. The run then continues with clean, glassy mornings into the second week, with the 10th, 11th, and 12th of August mornings all showing good, clean conditions with 3ft to 4ft SSW swell and solid energy in the 500-600 range. Good times ahead.
Rusty, signing off.

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.
