The Lowdown

G'day, I'm Rusty, and I've got the goods on what's shaping up for Cabo Blanco.

We've got a run of small but often glassy waves kicking off from Monday the 14th, stretching right through to the end of the month. The first standout period is the first few mornings, where conditions look prime for a sneaky paddle. The water is a very warm 86°, which is much warmer than normal for this time of year, so the spring suit might even be too much.

Let's get into it. Monday the 14th morning has a small 3 ft SSW swell, with a period of 9 seconds and 263 moderate energy. The wind is a glassy 3 mph from the NNE, making for clean conditions. The afternoon turns onshore and goes to shit. Tuesday the 15th sees the swell drop to 2 ft SW, but the glassy mornings keep coming, with a longer 18-second period, building energy to 369. This is a classic groundswell, better for the points and reefs, and combined with the 2 ft on Tuesday afternoon, the energy really bumps up to 421.

Wednesday the 16th morning is the first true highlight. We've got a 3 ft SSW swell with a 16-second period and energy jumping to 552. The wind is perfectly glassy and calm, so these waves will be clean as a whistle. The afternoon brings a risk of t-storms and an onshore breeze, so get out early.

The mornings of Thursday the 17th and Friday the 18th offer more of the same, with clean, glassy conditions on 3 ft and 2 ft SW swells, periods dropping to 14 and 13 seconds. The energy remains moderate. The weekend of the 19th and 20th is a mixed bag. Saturday has a tiny 2 ft SW swell, but Sunday the 20th morning is a standout: a 2 ft SW swell with a very long 19-second period, and 507 moderate energy. Glassy conditions again.

Then we hit a bit of a lull from the 21st to the 25th. The swells stay small, mostly 2 ft to 3 ft, and the winds get a bit messy in the afternoons, but the glassy mornings and the odd cross-offshore keep the dawn patrol worthwhile. The energy drops back into the low 200s by the 24th and 25th.

Now for the real event. Towards the end of the month, we see a big pulse. On Saturday the 26th, a 8 ft W swell rolls in with a short period of 8 seconds. The energy is massive, hitting 1785 in the morning, dropping to 1265 in the afternoon. That afternoon, the wind swings to a clean cross-offshore from the NNW. This is for experienced surfers only, and it's a damn good option for them. This size and period will be fat and challenging at a beach break, but with those offshore winds, it's a big, powerful wave. This is the standout swell of the whole outlook. Sunday the 27th drops to a 4 ft W swell with a 10-second period and 600 energy, still very good with a glassy morning.

The very end of the period runs out of steam. Monday the 28th is messy with a 3 ft W swell, though Tuesday the 29th morning brings back the clean conditions with a 2 ft SSW swell and 13-second period.

Overall, the dawn patrols from Monday the 14th through to Wednesday the 16th are the most consistent, clean, and surfable for everyone. The big-money call is the Saturday the 26th afternoon for the experts. There are no long gaps with zero options, just a mellow middle week.

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.
