The Lowdown
Right, folks, Rusty here. Let’s have a look at what’s going on.
We’ve got a solid pulse of Southern Ocean energy pushing into Praia Cardoso, but it’s a mixed bag. The big stuff arrives mid-week, though the wind is going to be the main character here. The best windows are short, so don’t sleep on them.
Wednesday the 12th sees a solid 7ft swell from the south, with a 12-second period, rolling in. The energy is strong (1346). It’s a bit of a shame the wind is a cross-off from the NNE at 12 mph, but it’s clean. The morning is a little marginal, but the afternoon gets better. The height drops to 7ft, but the wind eases to 9 mph, and the conditions are clean. This is the standout window for the week. It’s solid, experienced surf, so if you’re a beginner, this one is a bit too big for you.
Thursday morning the 13th, the swell builds to 7ft from the south, now with a very long 14-second period – that’s proper groundswell energy (1841). But the wind swings to a cross-shore from the SW at 6 mph, and the conditions get a bit lumpy. The forecast is marginal. The afternoon is a write-off with onshore wind.
Friday the 14th, the swell drops a touch to 6ft, but the wind is howling cross-shore from the ENE at 16 mph. It’s a choppy mess. Not worth it.
The swell continues to fade over the weekend. Saturday the 15th has some waist-high 4ft leftovers, but the wind is a fresh 19 mph. It’s clean but weak.
From Sunday the 16th right through to Thursday the 21st, it’s a proper flat spell. We’re looking at knee-high dribble or less, with the energy dropping to near zero. The water temperature is about average for the time of year.
There’s a glimmer of hope on Thursday the 20th. A small 4ft SSW swell with an 8-second period and a light WSW wind at 3 mph makes for some glassy, clean conditions. It’s small, but it’s rideable.
Then, on Tuesday the 25th, a new south swell arrives. We’re looking at a solid 7ft, the same direction as the sweet spot for this break, with a 12-second period. The wind is light from the WSW at 6 mph, keeping it clean. The energy is strong (1463). This is a long-range call, so keep an eye on it, but it’s a promising one.
So, the best of the lot is Wednesday afternoon the 12th. The wind is manageable, the swell is solid, and the waves are clean. For the long-range, Tuesday the 25th is the one to circle.
Rusty.

Information about the Praia Cardoso Surf forecast
The above surf forecast table for Praia Cardoso provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia Cardoso can be found by selecting the local surf guide option on the grey menu. Our Praia Cardoso 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 (Praia Cardoso) 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 Praia Cardoso 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.
