Table - best surf conditions forecast for Cabo Blanco over the next 16 days.
Alright, let’s break it down for the next 16 days. It’s all about Cabo Blanco. The water is running at 87°, which is way warmer than usual – about 4° above average, so you’re swimming in a bath.
First surf shows up Thursday afternoon, 9 July, but it’s a bit messy with a risk of thunderstorms and a light onshore wind. Swell is 4ft from the SSW with a 16-second period, moderate energy (689). Not the best, but it’s there.
The real standout is Friday morning, 10 July. Glassy calm, no wind, with a 3ft SSW swell, 15-second period, and moderate energy (583). Clean, long-period groundswell – perfect for a morning paddle.
Saturday morning, 11 July, is another beauty. Glassy conditions, 4ft SSW swell, 16-second period, and energy at 824. Wind is light from the NNW, offshore and clean. The afternoons get messy, but mornings are golden.
Sunday morning, 12 July, stays glassy with a 4ft SSW swell, 14-second period, and moderate energy (569). The pattern holds: clean mornings, breezy afternoons.
Monday morning, 13 July, offers a 3ft SSW swell, 13-second period, and glassy NE wind. Energy is moderate (580). Small but clean.
The absolute best of the run is Tuesday morning, 21 July. Glassy, light east wind, 4ft SSW swell with a 14-second period, and energy at 790. That’s a morning to mark on the calendar.
Then Friday morning, 24 July, brings a bigger pulse – 5ft from the SSW, 12-second period, energy at 752. Glassy with a risk of thunderstorms. This is the biggest swell of the forecast, and if the wind stays off, it’ll be a ripper for experienced surfers.
Bottom line: the mornings are the ticket. Cabo Blanco is the only game in town, and it’s consistently offering clean, fun waves. The 21st and 24th are the standouts.

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.
